Inline Flow-through Fluid Temperature Sensor

Thermometrics Inline Flow-Through Fluid Temperature Sensor provides inline fluid temperature measurement in heat exchange systems. Its design allows for convenient placement of the sensor at inlet/outlet locations for temperature control, or cooling/heating efficiency measurements, in devices, such as heat exchangers, radiators, and Electric Vehicle (EV) battery packs.

The Inline Flow-Through Fluid Temperature Sensor is based on NTC thermistor technology. When applied to a voltage divider system, a voltage signal that is proportional to the change in fluid temperature is obtained. The voltage divider system is generally contained in the OEM/Tier 1 control module.
