Product Description

BH-WS  4-20mA sewage level sensor  for harsh environments

Introduction: 

BH-WS sewage level sensor 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. 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

Product  Features:                                                                                                                  

1. Specially designed for harsh environments
2. Explosion-proof marking : ExiaIICT6
3. High protection :  IP68
4. Full 316L stainless steel structure with excellent corrosion resistance
5. High precision and good stability

Applications:

1. Compatible with 316LSS,noncorrosive liquids
2. Monitoring of oil level in diesel tanks, fuel tanks, and other fuel containers
3. Level measurement in polluted liquids, such as sludge tanks, clarifiers, digesters, alum tanks, chemical storage tanks, sewage pits, and water reservoirs
