Product Description

BH93420-III Oil Level Sensor with Display

The BH93420-III oil level sensor features a highly precise Piezoresistive diffused silicon pressure sensor for accurate liquid level measurement. It converts static pressure into standard 4-20mA output signals with linear relationship to liquid level.

Key Features

Split-type design for easy on-site wiring and calibration
Integrated LED display for real-time monitoring
Explosion-proof rating: ExiaIICT6
High protection rating: IP68
Multiple cable options: PE, PU, PTFE

Applications

Compatible with 316L stainless steel and non-corrosive liquids
Water level monitoring for sewage, industrial water, municipal water systems, tanks, wells, rivers, seawater, and lakes
Diesel, fuel, and oil tank level monitoring
