High Pressure Small Structure 400MPa Pressure Sensor
WP401B High Pressure Compact Pressure Sensor can be applied as a process control tool in a variety of industrial operations:
- ✦ Oil Refinery
- ✦ Air Separation
- ✦ Power Station
- ✦ Pump & Valve
- ✦ Gas Pipelines
- ✦ CNG/LNG Station
- ✦ Plastics Production
- ✦ Mechanical Equipment
Vary from regular models, WP401B for high pressure application adopts spherical curved structure of wetted part to reinforce tightness and erosion resistance against high pressure. A small dampener bar is mounted inside the pressure inlet orifice, protecting sensor element from instantaneous high pressure shock. The modifications enable the product well fit the large measuring range > 100MPa.
Outstanding cost-effective performance
lightweight robust and well sealed enclosure
Ease of installation and maintenance
Unique structure designed for high pressure
Suitable for mounting on narrow space
Anti-corrosion material for aggressive media
Communication Modbus and HART choice
Indicator with 2-relay alarm available
