Differential pressure transmitter P 34

Special features

• Measurement of differential pressure, volume flow or P-/T-compensated volume flow (optional) possible
• Volume flow can be configured via k-factor, dPmax/Vmax or 20 individual values
• Scaling, characteristic line form and many other parameters can be set via PC-software (optional)
• With USB interface
• 2 floating switching relays (optional)
• Output signal can be configured 0 .. 10 V or 0/4 .. 20 mA
• Highly stable measurements thanks to cyclical self-calibration of the zero point
• Can be calibrated
• Suitable for top-hat rail mounting in control cabinets
• Delivery possible already completely integrated into the control cabinet (on request
