Exergen Network Card IRt cXMTR User Manual

Transmitter  
The t/c.XMTR is specifically designed to interface any model IRt/c by a  
simple thermocouple connector or splice. The two wire current loop can  
be used in any conventional 4-20mA, 0-5V or 0-10V circuit that is scaled  
for the temperature range of interest.

In-Line Pre-Calibrated 4-20  
mATransmitter  
For OEMs, IRt/c sensors and t/c.XMTR can be supplied pre-wired  
together.  
· Use any existing wiring, for easy low cost installation  
· Use existing PLC, computer or controller inputs  
· In line design requires no mechanical support  
· Pre-calibrated for IRt/c type, no span or zero adjustment neces-

Cooling Jacket Kits  
CJK-1  
for IRt/c, IRt/c.3X, IRt/c.1X  
Water/Air Cooling  
A convenient and inexpensive kit makes it possible  
to use the IRt/c with air, water, or both for service in  
harsh environments. Measuring only 1" x 4.16" (25 x  
106 mm) overall, the CJK-1 is physically small  
enough to fit into tight areas and closely monitor  
process temperatures from the optimum position - up  
close. With its all stainless steel housing, it can  
withstand the harshest environments.

Pumps for Purge Air  
APK-1 120VAC  
The convenient Air Pump Kit allows for fast and easy installation of  
an air source suitable for maintaining optical cleanliness of IRt/c’s in  
dirty, dusty environments. Its air flow is sufficient to keep up to five  
IRt/c.2, or one IRt/c.5 clean. Additionally, the air flow is sufficient to  
allow an IRt/c.2 to operate in ambients up to 240°F (115°C). The  
pump can be mounted on either horizontal or vertical surfaces.

Specifications:  
Air Pump - 120VAC, 120 cu.in./min (1960cc/min). Available in  
12VDC.

Gooseneck Mounting Kit  
GMK-1  
For fast, convenient testing  
of IRt/cs  
For fast and convenient mounting of IRt/c’s, especially for testing, the  
Gooseneck Mounting Kit provides an inexpensive method to quickly  
install an IRt/c directly on the production line. Its heavy duty design  
provides excellent stiffness for reliable positioning. Clamps are fabricated  
of aluminum for durable performance. The sensor clamp fits all IRt/c  
models (the MB-1 Mounting Bracket is required for Adjustable IRt/c  
models),
