Product Description
BP93420-III Pressure Transmitter — a 10 kPa to 60 MPa industrial pressure transmitter delivering a 4–20 mA output for water, oil, and level measurement, available with a local display. Built on an HT-series silicon piezoresistive oil-filled isolation core, it converts sensor signals into standard output for reliable pressure monitoring in demanding industrial environments.
The BP93420-III pressure transmitter adopts the HT series silicon piezoresistive isolation oil-filled core as its signal measuring element. The signal processing circuit converts the sensor output into a standard industrial signal. Every unit undergoes rigorous testing and aging screening at the component, semi-finished, and finished product stages, ensuring stable and reliable performance with strong anti-interference capability. The pressure interface is available in a variety of forms to suit different installation requirements.
- Wide measuring range with diverse pressure interface forms and IP65 protection level.
- Multiple output signal options, with adjustable and displayable configurations.
- Adjustable zero point and full scale for precise calibration.
- High-precision, high-performance diffused silicon piezoresistive pressure sensor core.
- Measurement of non-corrosive gases and liquids compatible with 316L stainless steel.
- Petroleum, chemical, metallurgy, power, and hydrology industries.
- Pressure measurement and control in harsh outdoor industrial environments.
- Hydraulic and pneumatic control systems.
