Product Description

BH93420-III Water Level Transmitter

The BH93420-III water level transmitter utilizes a highly precise piezoresistive diffused silicon pressure sensor to measure static pressure directly related to water level. This measurement is converted into standard signal output through amplification circuitry, establishing a linear relationship between output signal and liquid level for precise and accurate water level monitoring.

Product Features

Split-type design for easy on-site wiring and calibration
LED display for clear readings
Explosion-proof rating: ExiaIICT6
High protection rating: IP68
Cable options: PE, PU, PTFE

Applications

Compatible with 316LSS and non-corrosive liquids
Monitoring water levels in sewage, industrial and municipal water systems, water tanks, wells, rivers, seawater, and lakes
Diesel, fuel, and other oil tank level monitoring
