Product Description
BH93420-III Liquid Pressure Sensor Transmitter
High-precision 4-20mA liquid pressure sensor transmitter with LCD display for accurate water level measurement applications.
Product Overview
The BH93420-III water level transmitter utilizes a highly precise Piezoresistive diffused silicon pressure sensor to measure static pressure directly related to water level. The device converts this measurement 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
- Clear 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 and municipal water systems, water tanks, wells, rivers, seawater, and lakes
- Diesel, fuel, and other oil tank level monitoring
