Product Overview

The Amphenol Advanced Sensors Thermometrics JS8741 is an integrated pipe clip surface temperature sensor designed for monitoring fluid or gas temperatures within circulation systems. Its easy-to-mount, spring-loaded galvanized steel clip ensures high sensitivity and a compact design. The sensor features an integrated connector with a locking mechanism and is VW75174 approved, offering IP57 ingress protection. It is ideal for applications such as engine coolant temperature, battery pack coolant line temperature, process flow management, HVAC water and refrigeration, and home appliances. The system control module receives temperature readings to manage overall system temperature, including engine, heater, or industrial supply line temperatures.
