Differential pressure transmitter PIZ Halstrup Walcher Việt Nam, đại lý hãng Halstrup Walcher

Differential pressure transmitter with two-wire technology (cable-safer) for measurement of positive or negative differential pressures

Special features

• High level of accuracy and long-term stability
• Little zero point drift or hysteresis; largely independent of temperature
• Measurement of positive and negative differential pressures
• LCD display (optional)
• Output signal 4 .. 20 mA
• Factory-adjusted attenuation of the output signal of up to 5 s possible (optional)
• Can be calibrated

This differential pressure transmitter reduces wiring costs thanks to its two-wire technology. An optional display allows measurement values to be read directly on-site in Pa, kPa or mmH₂O. An optional time constant (up to 5s) allows the instrument to generate an attenuated output signal, even under fluctuating pressure conditions. The instrument is available with an ISO factory calibration or DAkkS-accredited calibration certificate (optional).
