Exergen Corporation

IRt/c sensors are now used in many of the most automated factories in the world, helping to manufacture higher quality products at lower cost, everything from tires and steel, to bread and chocolates.

IRt/c sensors have been designed into the most advanced OEM products in the world, from controlling the temperature fusing of colored toner inks in the worlds' first digital color printing press, to measuring temperature of tiny blood samples in the world's first portable blood analyzer to perform accurate blood tests in under two minutes.

The ease-of-use, speed, accuracy, and high quality at low cost, of IRt/c sensors helped make such dramatic new technologies possible.

WHAT INFORMATION IS NEEDED TO SELECT THE RIGHT PRODUCT?

Portable or fixed in place?

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

If the requirement is for a fixed, in place sensor, see any IRt/c below.

Environment?

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

Material?

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

Ambient temperature?

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

Optics?

Field of view (FOV) is defined as the distance to spot size, you want the spot size 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

Output?

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

Target tempearture variation and temperature range?
If the target temperature variation is < +/- 40F wide and the target temperature is < 1200F use any Precalibrated IRt/c

If the target temperature variation is > +/- 40F wide 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 wide and the target temperature range is -50-5000F use: any Adjustable IRt/c

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!

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

ORDERING INFORMATION

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

Example: IRt/c.3X - K - 240F/120C

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.
