PWP301 Micro-differential Pressure Transducer With Display
The micro-differential pressure transmitter uses silicon MEMS micro-pressure chip. After temperature compensation, linear compensation, signal amplification, V/I conversion, anti-surge, reverse polarity protection and other transmission circuit signal processing, it outputs industry standard signal for example 4-20mA. It features full digital calibration, no moving potentiometer, improved temperature drift performance and stability.
This series of product chips adopts two isolation protection methods.
Transmitters with a range <5kPa are mainly used for differential pressure measurement of non-corrosive airs; Transmitters with a range ≥ 5kPa are suitable for measuring non-corrosive medias compatible with stainless steel and sealing ring materials.
Features:
- MEMS micro-pressure sensor chip
- Advanced circuit linearity
- Digital temperature compensation
- Compact and easy to install
- Protection class IP66
- Anti-surge, reverse polarity protection
