PWP300 Differential Pressure Transducer
At the core of these pressure sensors is a silicon sensing element mounted within a high integrity seal assembly that is fully isolated from the pressure media by a welded 316L stainless steel diaphragm. The pressure to be measured acts on the sensor’s diaphragm and is transferred through incompressible silicone oil to a micro machined silicon strain gauge configured as a Wheatstone bridge.
The advantages of silicon compared with metal-based strain gauge pressure sensors are higher sensitivity, better repeatability, higher signal to noise ratio, higher overload and a significantly higher long-term stability.
Features:
- Pressure ranges from -0.1MPa to 3.5MPa
- Explosion proof available with Exd and Exia
- Fully 316L welded robust construction
- High stability, low drift
- EMC protection, over voltage protection
- Strongly compatible with air, oil, hydraulic and water pressure
