WP401B Compact Design Cylinder RS-485 Air Pressure Sensor
WP401B Compact Pressure Sensor can be used to measure & control liquid, gas and fluid pressure in following fields:
- Chemical industry
- Oil & Gas, Petroleum
- Thermal Power, Water supply
- Machine Building
- CNG / LNG Gas Station
- Offshore and Marine
- Pumps and Compressors
WP401B air pressure transmitters adopt advanced imported cutting-edge sensor element that is combined with the solid state integrated technological and isolate diaphragm technology. The compact pressure sensor features a simple and lightweight design with all-welded stainless steel column shell, providing a reliable and precise solution that works well under various conditions.
WP401B pressure sensor's high stability up to 0.2%FS/year improves efficiency and reduces maintenance costs. The stainless steel housing case provides IP65 ingress protection and up to IP68 for immersion variant. The wetted part is fully-welded and manufactured from stainless steel 304/316L or other alloy to resist corrosive media. As the manufacturer, our WP401B series pressure transducers are highly customizable in output signal, material, connection, digital display and other technical parameters.
