Overview
The Immersion Temperature Sensor is made for thermowell mounting and temperature measurement in water pipes, water tanks or
cooling tower sump applications. The rigid probe is made of Stainless Steel and made in different lengths for a custom thermowell fit.
Enclosure mounting styles come in plastic or metal for both NEMA 1 and NEMA 4 applications and are all plenum rated.

Page 7: Wiring & Termination
Wiring & Termination Carrier recommends using twisted pair of at least 22AWG and sealant filled connectors for all wire connections. Larger gauge wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes. Do NOT run this device’s wiring in the same conduit as high or low voltage AC power wiring.
