PIZ Differential Pressure Transducer as a two-wire system
Product Description
Differential pressure transmitter with two-wire technology(cable-safer) for measurement of positive or negative differentialpressures
Special features
- High level of accuracy and long-term stability
- Little zero point drift or hysteresis; largely independent oftemperature
- Measurement of positive and negative differentialpressures
- LCD display (optional)
- Output signal 4 .. 20 mA
- Factory-adjusted attenuation of the output signal of up to 5 spossible (optional)
- Can be calibrated
This differential pressure transmitter reduces wiring coststhanks to its two-wire technology. An optional
display allows measurement values to be read directly on-site inPa, kPa or mmH2O. An optional time
constant (up to 5s) allows the instrument to generate anattenuated output signal, even under fluctuating
pressure conditions. The instrument is available with an ISOfactory calibration or DAkkS calibration
certificate (optional).
