Product Description

BH93420-III Liquid Level Transmitter

High-precision water leak sensor and level transmitter designed for fuel meters and pressure monitoring applications with 4-20mA output and LED display.

Product Overview

The BH93420-III liquid level sensor utilizes a highly precise Piezoresistive diffused silicon pressure sensor to measure static pressure, which directly correlates 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 measurement.

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
Multiple cable options: PE, PU, PTFE

Applications

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