Harsh Environment Liquid Pressure Transmitter


Liquid Pressure Transmitter 316L


316L Piezoresistive Silicon Pressure Sensor

Product Description





Introduction of BH-WS water level transmitter: 

BH-WS water level transmitter utilizes a high-precision piezoresistive silicon pressure sensor as the sensitive measuring element. It features a robust and durable design with a full 316L stainless steel construction. There may be suspended solids, sediments and other impurities in the sewage, and the input level transmitter usually adopts an anti-clogging design to ensure that the probe of the sensor is not easy to be blocked and maintain accurate level measurement.This transmitter is suitable for measuring liquid levels in environments with contaminated liquids,such as sludge tanks,  clarifiers,  digester, alum tanks, chemical storage tanks, oil tanks, lime slurry, sewage pits, and water reservoirs
