Differential pressure sensor based on static pressure measurement (diaphragm) available with 3 different measuring ranges. Configuration and calibration directly by the transmitter. Ideal for HVAC, clean room applications or FFU control (Filter Fan Units)
Drift-free and long-term stability due to automatic zero point calibration
Large, clear display
Easy to configure and calibrate
Scalable analog signal: mA or V
Integrated switching contact with configurable switching threshold function
Tube length possible up to 100 metres
3 measuring ranges available -50 to +50 / 0-500 / 0-2000 Pascal
Measuring ranges: -50…+50 Pa / 0…+500 Pa / 0…+2000 Pa
Measuring accuracy: +/- 50: +/- 0.5% (of the entire measuring range)
at +20°C 500 : +/-0.25% (of the entire measuring range)
2000 : +/- 0.5% (of the total measuring range)
Offset drift: < 2 Pa / year (with automatic zero adjustment)
Configuration: only possible via device keyboard
