General Description

1.1 Introduction

The OS550 Series Industrial Infrared (IR) Thermometers provide

non-contact temperature measurement up to 2500°F (1371°C). They

offer effective solutions for many non-contact temperature

applications, including the following:

• Predictive Maintenance: Tracking temperature shifts

which indicate pending failure in solenoid valves.

• Energy Auditing: Locating wall insulation voids to reduce

building heating costs.

• Food Processing: Taking accurate temperature readings

without direct contact with the food or packaging material.

The IR thermometer provides a custom backlit dual digital LCD

that displays both current and minimum, maximum, average or

differential temperatures. This versatile instrument provides:

• Measurable target distances from 5" to

approximately 200'

• Emissivity adjustable from 0.1 to 1.00 in 0.01 steps provides

ease of use when measuring a variety of surfaces.

• Continuous temperature measurement up to 4 times per

second.

• Audible and visual alarms. The high and low alarm points

are set via the keypad.

• Analog output, 1 mV/degree,4-20mA or 0-5VDC

which allows interfacing with data acquisition equipment

(including chart recorders, dataloggers and computers)

• RS232 serial communication to a PC or printer. This allows

downloading data for further analysis (OS552, OS553 and

OS554 only).

• Ambient target temperature compensation. This provides

more accuracy for measuring low emissivity targets.

• Record up to 100 temperature data points. Review the

recorded data on the thermometer LCD, as well as

downloading the data to a PC (OS553 and OS554 only).

• Last temperature recall.

• Backlit display useful in low ambient light conditions

• Laser Sighting is optional.

Using the Infrared Thermometer/Transmitter

3.4 Measurement Techniques

You can use the IR Thermometer to collect temperature data in any

one of five different ways:

• Spot Measurement — Measures the temperature of discrete objects

such as motor bearings, engine exhaust manifolds, etc.:

1. Aim the sensor head at the desired target.

2. If necessary, adjust the emissivity using the

keys.

and

3. Read the temperature.

• Differential Measurement — Measures the temperature differential

between two spots (the maximum and minimum temperatures

viewed)

1. Aim the thermometer at the first spot.

2. If necessary, adjust the emissivity.

3. Aim at the second spot.

4. Adjust the emissivity of the second spot if required.

5. To display the differential temperature, press the

key until

“dIF” appears on the display.

6. Read the differential temperature from the upper display.

• Static Surface Scan – Measures the temperature across a static

surface:

1. Aim the thermometer’s sensor head at a starting point.

2. If necessary, adjust the emissivity.

3. Slowly move the thermometer’s sensor head so that the line of

sight sweeps across the surface. The thermometer measures the

temperature at each point on the surface.

4. To record the temperature profile across the surface, connect

the IR thermometer to a strip chart recorder that will accept an

analog input matching the analog output of the model OS550

that you have selected.

Using the Infrared Thermometer/Transmitter

•

Moving Surface Scan - Measures the Temperature of Points on

a Moving Surface:

1. Mount the sensor head and aim at your target.

2. If necessary, adjust the emissivity. The thermometer is now set

up for measuring the temperature of a moving surface.

3. To record the temperature profile of the moving surface,

connect the IR thermometer to a strip chart recorder or Data

logger.

•

Fixed Point Monitoring Over Time - Monitors the temperature

at a fixed point over time:

1. Mount the sensor head and aim at your target

2. If necessary, adjust the emissivity.

Connect the analog output of the thermometer to a strip chart

recorder or datalogger

4. The thermometer is now set up for unattended monitoring of

temperature over time. You can also download the

temperature readings to a serial printer or computer.

Laser Sight Accessory

4.2 Description

A laser sighting accessory is available to aid in the sensor head

installation process. When installing a line of sight Infrared

transducer with a small spot size and long target distance, it is

sometimes difficult to locate the center of the focused spot and the

material to be measured. To solve this problem, we offer a laser

sighting accessory OS550-LS that will install onto the front of the

OS550 series sensor head. This compact tool provides the installer

with a true line of sight laser dot up to a distance of 12.2 meters

(40') in the center of the IR optical path taking the guess work out of

proper alignment during the installation. The laser is powered by a

power pack with replaceable batteries and interconnect cable.

Appendix: How Infrared Thermometry Works

Thermal Radiation

Heat is transferred from all objects via radiation in the form of

electromagnetic waves or by conduction or convection. All objects

having a temperature greater than absolute zero (-273°C, -459°F,

0 K) radiate energy. The thermal energy radiated by an object

increases as the object gets hotter. Measurement of this thermal

energy allows an infrared thermometer to calculate the object’s

temperature if the emissivity (blackness) is known. Generally, it is

convenient to measure the amount of radiated energy in the

infrared part of an object’s radiation spectrum.

Figure A-1 shows a block diagram of an infrared radiation

thermometer. Energy from the object is focused by the lens onto the

detector. As the detector heats up, it sends out an electrical signal,

which in turn is amplified and sent to the circuitry of the

thermometer. The thermometer software then calculates the

temperature of the object.

Appendix: How Infrared Thermometry Works

Blackbody

When thermal radiation falls on an object, part of the energy is

transmitted through the object, part is reflected and part is

absorbed. A blackbody is defined as an ideal object that absorbs all

the radiation incident upon it. The best example of a real object that

acts like a blackbody is a small hole drilled deep into a large opaque

cavity. Thermal radiation entering the cavity is internally reflected

and has little chance of escaping the cavity before it is fully

absorbed.

Emissivity is defined as the ratio of energy radiated by an object to

that of the energy radiated by a blackbody. By definition, the

emissivity of a blackbody is 1. Most objects are considered gray

objects with an emissivity between 0 and 1. Various emissivities for

common materials are shown in Appendix B.

Spectral Distribution

Objects radiate energy at

different wavelengths, but

not with constant intensity

at each wavelength. Figure

A-2 shows the energy

radiated by a blackbody at

various temperatures as a

function of wavelength. As

a body is heated, the

intensity of the radiated

energy increases and the

peak of the curve shifts

towards the shorter

wavelength end of the

spectrum. The total area

under a spectral

distribution curve is

proportional to the total

energy radiated by the

blackbody at a given

temperature.

Relative emission from a blackbody versus wavelength.

The area under the curve corresponds to the total ener-

gy, and is proportional to the absolute temperature to

the 4th power. The peak of the spectral distribution

curve shifts to shorter wavelengths as the temperature

increases.

Appendix: How Infrared Thermometry Works

Wien’s Displacement Law describes the exact mathematical

relationship between the temperature of a blackbody and the

wavelength of the maximum intensity radiation.

where λ = wavelength measured in microns

T = temperature in Kelvin

Calculating Temperature

The net thermal power radiated by an object has been shown to

depend on its emissivity, its temperature and that of the ambient

temperature around the object. A very useful equation known

today as the Stefan-Boltzmann Law has been shown both

theoretically and empirically to describe the relationship.

I = thermal power in watts/meter

ε = Emissivity

σ = 5.6703 x 10 watts/meter x K (Stefan’s constant)

-8

T = temperature of object in Kelvin

T = temperature of ambient surroundings in Kelvin

The infrared thermometer uses this equation directly in calculating

the temperature of an object. The incident power is measured by

the infrared detector. The emissivity of the object is determined by

the user. The ambient temperature is measured by a sensor inside

the thermometer. With all quantities known, the thermometer uses

the Stefan-Bolzmann Law to calculate and output the temperature

of the object.

Appendix: How Infrared Thermometry Works

Optics Field of View

Accurate measurement of temperature via infrared means depends

strongly on the size of the object and the distance between the

thermometer and the object. All optical devices (e.g. cameras,

microscopes, infrared thermometers) have an angle of vision,

known as a field of view or FOV, within which they see all objects.

In particular, the thermometer will measure a fixed proportion of

the energy radiated by all objects within its FOV. The user must

guarantee that the distance between the thermometer and the object

is defined so that only that object fills the FOV of the instrument.

Referring to Figure A-3, Objects “X” and “Y” are within the FOV of

the thermometer. The measured temperature would fall somewhere

between the actual temperatures of the two objects. In order to

measure the temperature of Object “X” accurately, Object “Y” would

need to be removed. In order to measure the temperature of Object

“Y” accurately, the user would need to move closer to Object “Y”

until it completely filled the FOV of the thermometer. Alternatively,

the user could measure the temperature of Object “Y” with a

thermometer with a smaller FOV.

Figure A-3. Field of View of a Thermometer/Transmitter

The distance-to-spot size ratio ( ⁄S) defines the field of view (FOV).

Thus, a ⁄

= 10 gives you approximately a 1' spot size at a distance of

10'. For accurate spot size values, refer to the Field of View diagrams

shown in Figures 3-3 through 3-8.

Appendix: Emissivity Values

Table B-1 provides guidelines for estimating the emissivity of various

common materials. Actual emissivity, especially of metals, can vary

greatly depending upon surface finish, oxidation, or the presence of

contaminants. Also, emissivity or infrared radiation for some materials

varies with wavelength and temperature. To determine the exact

emissivities for most applications, follow the procedures in Appendix C.

Appendix: Determining an Unknown Emissivity

In Appendix A, we showed how emissivity is an important

parameter in calculating the temperature of an object via infrared

means. In this section we discuss how to determine a specific

emissivity value. If you know the material of the object, use Table

B-1 in Appendix B to look up its approximate emissivity. Most

organic materials such as plastics, cloth, or wood have an emissivity

of about 0.95. For this reason, we use 0.95 as the default emissivity

setting in the OS551/OS552, OS553 and OS554 Thermometers.

For objects of unknown material or for very precise measurements,

use one of the following methods to determine a specific emissivity

value.

Method 1

1. Measure and record the temperature of the object using a contact

temperature probe such as a thermocouple or RTD.

2. Aim the thermometer at the object.

3. Adjust the emissivity until the temperature reading of the

thermometer equals the temperature measured in Step 1.

Method 2

1. Heat the object (or at least a sample of the object material) on top

of a heating plate to a known temperature. Make sure the

thermometer and the air surrounding the heating plate are at the

same temperature.

2. Measure the temperature of the object material with the

thermometer. Make sure that the object fills the FOV of the

thermometer.

3. Adjust the emissivity until the temperature reading of the

thermometer equals the known temperature of Step 1.

Appendix: Determining an Unknown Emissivity

Method 3

1. Use this method to measure objects at temperatures below

500°F (260°C).

2. Place a large piece of masking tape on the object (or at least a

sample of the object material). Allow time for the masking tape to

reach the object temperature.

3. Set the emissivity of the thermometer to 0.95. Use the thermometer

to measure and record the temperature of the masking tape - Area

“A” in Figure C-1. Make sure that the area of the object covered

with masking tape fills the FOV of the thermometer.

4. Aim the thermometer at Area “B” as shown in Figure C-1 Make

sure that Area “B” is as close as possible to Area “A”.

5. Adjust the emissivity of the thermometer until the temperature

reading equals the temperature found in Step 3.

Appendix: Determining an Unknown Emissivity

Method 4

1. Paint a sample of the object material with flat black lacquer paint.

2. Set the emissivity to 0.97 and measure and record the temperature

of the painted portion of the sample material - Area “A” in Figure

C-1. Make sure that the painted area of object material fills the

FOV of the thermometer.

3. Aim the thermometer at another spot on the target - Area “B” in

Figure C-1.

4. Adjust the emissivity of the thermometer until the temperature

reading equals the temperature found in Step 2.

Method 5

1. Use this method where practical to measure objects at

temperatures above 500°F (260°C).

2. Drill a 1.5" (35 mm) diameter hole in a sample of the object

material to a depth of 5" (127 mm). This hole closely resembles a

blackbody (refer to Appendix A).

of the hole in the sample material - Area “A” in Figure C-2. Make

sure that the hole fills the FOV of the thermometer.

4. Aim the thermometer at another spot on the target as close as

possible to Area “A” (Area “B” in Figure C-2).
