High Accuracy Specialty Sensors

DESCRIPTION

The TB strap-on sensor uses a clamp to secure the unit to a pipe and a copper sensing
plate for fast temperature response. The TB is perfect for secondary measurement of
water temperature typical in retrot applications. It includes a steel mounting box
for wire termination and easy conduit connection.

The TRA Series stainless steel remote probe is designed for high accuracy in remote
temperature sensing applications. The TRA can be used in numerous refrigeration
applications or can be mounted on pipes for chilled or heated water temperature
sensing. It is easily installed and includes a durable stainless steel sensing probe and
a two-wire twisted pair wire with strain relief. Multiple cable lengths are available
for added exibility.
