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.

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-
sary
· Hermetically sealed construction exceeds NEMA 4, 4X, IP65, 66,

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.

Extraordinarily efficient in design, the CJK requires
only .05 gpm (190 cc/min) of water and 0.1 CFM
(3000 cc/min) of air to protect an IRt/c at 1000°F
(540°C).

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.
APK-2 12VDC
Specifications:
• Air Pump - 120VAC, 120 cu.in./min (1960cc/min). Available in
12VDC.
• Vinyl Tubing - 10 ft (3m), .25" (6mm) OD, .17" (4mm) ID.
• Standoff Mounts - allow pump to be secured vertically or
