Product Description

BH93420-III Digital Level Measuring Instrument

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

Key Features

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

Applications

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