Flow Switch | Flow Sensor / Thermal Wire Type Flow Switch Series

Active in various fields such as machinery, pharmaceuticals, food, semiconductors, air conditioning, industry, and processing plants! It has no moving parts and monitors with constant stable operation.

The EGE company's flow switch is equipped with two thermistors inside the sensor. The two thermistors are constantly supplied with a fixed amount of heat from the amplifier. Thermistor R2 is covered with a resin that has poor thermal conductivity and is maintained at a constant amount of heat. Meanwhile, thermistor R1 is cooled in accordance with the flow rate of the fluid flowing through the pipe, resulting in a difference in heat between R2 and R1. This difference in heat is used to determine the flow rate.
