Product Description

BH93420-III Split Level Transmitter Pressure Sensor

The Hengtong BH93420-III split level transmitter is a precision liquid level measurement sensor featuring 4-20mA output with LED display capability. This advanced sensor utilizes a highly precise piezoresistive diffused silicon pressure sensor to measure static pressure directly related to water level, converting it into standard signal output through amplification circuitry.

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, tanks, wells, rivers, seawater, and lakes
Diesel, fuel, and other oil tank level monitoring
