Intrinsic Safe Smart Pressure Transmitter with Local Display for Gauge Absolute Pressure
WNK5 series pressure transmitter is the high performance pressure transmitters provided by Hefei WNK Smart Technology Co., Ltd. It transforms the physical signal of pressure, differential pressure and level etc into standard signal, by collecting cell sensor and digital processing circuit.
Our WNK5 series has the best precision and signal uniformity by applying advanced specified integrated circuit digital technology. Each set of transmitter is ambient temperature compensated in our factory, to ensure max precision and mini drift in wide working temperature range.
Product advantage
1. High reference accuracy up to 0.05%.
2. Long-term drift ≤±0.25%URL for 1 year.
3. Hart, PROFIBUS-PA or FF protocol for option.
4. Intrinsically safe and flameproof explosion proof
5. Range down ratio 100:1
6. Smart type for easy calibration
Product application
1. Gauge & absolute pressure measurement in gases, steam or liquids in all areas of of engineering process and measurement.
2. Level, volume or mass measurement in liquids.
3. Working with detecting element, measure the flow of gases, steam and liquid flow.( volume and mass flow)
4. High pressure up to 700bar.
