Termékleírás
The Differential Pressure Transmitter PU/PI is a high-precision device designed for measuring positive and negative differential pressure. With its multiple accuracy classes, it is suitable for both HVAC applications and high-end laboratory environments.
The device offers high accuracy and long-term stability, combined with low zero drift, minimal hysteresis, and low temperature dependency, ensuring reliable and repeatable measurement results. An optional LC display allows direct on-site reading of measured values.
Depending on the version, the transmitter provides either a voltage output (PU: 0–10 V) or a current output (PI: 0/4–20 mA), enabling flexible integration into various systems. An optional output signal damping of up to 5 secondsensures stable readings even under fluctuating pressure conditions.
The transmitter is calibration-capable, with optional factory or DKD calibration certificates available. With the display option, measured values can be shown directly in Pa, kPa, or mmH₂O.
