The following guide will assist you with your model selection process, if you need further assistance, please email: industrial@exergen.com or call 617.923.9900, option #4.

WHAT INFORMATION IS NEEDED TO SELECT THE RIGHT PRODUCT?

Do you need a portable, handheld instrument or a fixed in place, continuously monitoring sensor?

If the requirement is for a portable, handheld infrared device, see our MICROSCANNERS below.

If the requirement is for a fixed, in place sensor, move on to the next series of questions.

How is the environment surrounding the sensor?

If the environment is clean, use any IRt/c

If the environment is dusty, dirty, or moist, use: SmartIRt/c, IRt/c.3X, IRt/c.3SV, IRt/c.5, IRt/c.10, adjustable IRt/c's, microIRt/c with APJ-1, or microIRt/c.4SV

What is the surface of your material like?

If the surface material finish is a non-metal or coated metal, use any IRt/c

If the surface material finish is a metal (> 500 F), use any adjustable IRt/c.xxA-x-LoE

If the surface material finish is a metal (< 500 F), you must coat the surface

What is the ambient temperature range surrounding the sensor?

If the ambient temperature at sensor location is < 160F/70C, use: IRt/c.01, IRt/c.03, IRt/c.07, or SmartIRt/c

If the ambient temperature at sensor location is <212F/100C, use: IRt/c, IRt/c.1X, IRt/c.3X, IRt/c.SV, IRt/c.3SV, microIRt/c, microIRt/c.SV

If the ambient temperature at sensor location is < 350F/170C, use: microIRt/c or microIRt/c.4 with APJ-1

If the ambient temperature at sensor location is <400F/200C, use: IRt/c.5, IRt/c.10 or any adjustable IRt/c

If the ambient temperature is <750F/450C, use CJK-2 cooling jackets

If the ambient temperature is < 1000F/540C, use CJK-1 water cooling jackets

How close will you mount the sensor to the target and what is the target size?

Field of view (FOV) is defined as the distance to spot size, you want the spot size on the target to be less than the target size (75% or less), for example if the target is 1" and the distance is 2", you want to use a 3:1 FOV which measures a 0.66" spot at 2".

If the field of view is 1:2 use: microIRt/c or microIRt/c.SV

If the field of view is 1:1 use: IRt/c, IRt/c.SV, IRt/c.1X, or IRt/c.01

If the field of view is 2:1 use: IRt/c.2

If the field of view is 3:1 use: IRt/c.3X, IRt/c.3SV, IRt/c.03, SmartIRt/c.3

If the field of view is 5:1 use: IRt/c.5 or SmartIRt/c.5

If the field of view is 7:1 use: IRt/c.07

If the field of view is 10:1 use: IRt/c.10 or IRt/c.10A

If the field of view is 20:1 use: IRt/c.20A or SmartIRt/c.20

If the field of view is 40:1 use: SmartIRt/c.40

If the field of view is 100:1 use: IRt/c.100A

What output is desired from the sensor and what is your input device ?

If a thermocouple output (mv) is desired use: Any Precalibrated or Adjustable IRt/c

If a 4-20mA output is desired use: SmartIRt/c or any IRt/c with XMTR

If a 0-5V, 0-10V or RS232 output is desired use: SmartIRt/c

What is your target temperature range, and optimized temperature point within that range ?
If the target temperature variation is < +/- 40F from the optimized temperature point, and the target temperature is < 1200F use any Precalibrated IRt/c


If the target temperature variation is > +/- 40F from the optimized temperature point and the target temperature range is -30 - 1832 F use: SmartIRt/c or Precalibrated IRt/c with programmable interface


If the target temperature variation is < +/- 40F from the optimized temperature point and the target temperature range is -50-5000F use: any Adjustable IRt/c

Are you looking to sense whether a hot object or adhesive is present on a line ?

If you are looking to detect the presence of a hot/cold object (like glue) or a change in temperature that is fast moving, use the SnakeEye thermal switch

Exergen Industrial Products Model Selection
PRECALIBRATED IRt/c's

IRt/c infrared thermocouples (t/c) require no power. Just wire them up to standard thermocouple controllers, PLC and computer t/c input cards, t/c displays, and t/c transmitters. It's that easy!

The precalibrated IRt/c's are designed to match t/c's at temperatures close to their calibration points, within 2% (see table below) all precalbrated IRt/c's can read outside the 2% linear range by utilizing signal output tables and polynomials.

GENERAL SPECIFICATIONS

SIGNAL OUTPUT : Thermocouple type J, K, E, T, over temperature range specified

POWER REQUIREMENTS: None

COLD JUNCTION COMPENSATION: By measuring instrument, as with conventional thermocouples

EMISSIVITY: 0.9 for non-metal surfaces

REPEATABILITY: +/- 0.01 C

AMBIENT TEMPERATURE COEFFICIENT: 0.02% of reading/F (0.04 %/ C) (see TN #90)

RESPONSE TIME CONSTANT : 0.1 seconds approximately

RESOLUTION: 0.0001 C approximately

SPECTRAL RESPONSE: 6.5 to 14 microns

OUTPUT CABLE: Twisted shielded pair of base thermocouple material (J,K,etc.), 3 ft (0.9 M) standard length, teflon sheathed rated to 392 F (200 C) continuous service (except IRt/c.01, .03, .07)

ORDERING INFORMATION

  • Select IRt/c(*) model. Example: IRt/c.3X
  • Select the thermocouple type (**) desired (J, K, etc.), add it to the model name.  Example: IRt/c.3X-K
  • Select the target temperature range. For example, to control a lamination process at 200 F (93 C), look at the following target temperature table for 200 F (93 C). Note the black area in the table indicates the "180F/90C" pre-calibrated range.

(Model) - (Thermocouple Type) - (Pre-Calibrated Temperature Range)

Example: IRt/c.3X - K - 180F/90C

heatshrink

The thermocouple type and pre-calibrated temperature range can be found on the heat shrink which is on the t/c cable going into the IRt/c.

Serial numbers are product independent and unique. They are etched on the housing of the unit. The model can not be determined or tracked by serial number. The serial number sequence is YYWWXXX

YY: Reverse digits of the year manufactured (i.e. 2008 would appear as "80")

WW: Reverse digits of the week manufactured (i.e. week 3 would appear as "30")

XXX: A sequential number by week of order, independent of product line.

These models allow for the user to calibrate the IRt/c’s to match a thermocouple in the temperature range they desire. The range adjustment screw is adjusted to calibrate for temperature range of interest and material properties (emissivity). Models for non-metals (HiE) and metals (LoE) are available.

GENERAL SPECIFICATIONS

same as precalibrated models, with the exception of emissivity, which is 0.2 for LoE models and 0.9 for HiE models
