Static Pressure Differential Pressure Transmitter Level Measurement Differential Level Sensor
BP93420DII Differential Pressure Transmitter utilizes piezoresistive diffused silicon sensor technology for precise differential pressure measurement in industrial applications.
Product Overview
The BP93420DII differential pressure transmitter employs piezoresistive diffused silicon sensor technology. When differential pressure from the measured medium acts on the corrugated diaphragms at both sensor ends, the Wheatstone bridge output signal maintains excellent linear correlation with differential pressure, ensuring accurate measurement. Ideal for gas and liquid differential pressure measurement in petroleum, chemical, power, and hydrology industries for pipeline applications.
Key Features
- Stainless steel structural design for compact size and easy installation
- Rigorous temperature compensation and aging screening for stable, reliable performance
- Flexible electrical interface options: plug-in or direct wiring
Applications
- Differential pressure measurement for gases and liquids in petroleum, chemical, power, and hydrology pipeline industries
- Industrial process monitoring in petroleum, chemical, metallurgy, power generation, and hydrology sectors
- Pressure measurement for pipelines and furnace chambers
