DIFFERENTIAL PRESSURE INDICATOR
DPI
Model summary
Each device has 4 selectable measuring ranges. Each device is individually temperature compensated.
4 range model
- AZ for autozero element*
- 2R for 2 relays
- D for display
DPI+/-500 (-AZ-2R) -D
DPI2500 (-AZ-2R) -D
*) -AZ model recommended when measuring pressures below 250 Pa.
**) %/FS from highest pressure range (including: general accuracy, temperature drift, linearity, hysteresis and repetition
error).
Initial value is the factory calibration accuracy, better accuracy can be achieved with span point calibration.
The device has 0...10V output and 1 or 2 relay outputs (depending on the model).
The Differential Pressure Indicator is delivered individually packed with standard accessories (see
accessories).
