ZPM – DIFFERENTIAL PRESSURE SENSOR

ZPM – DIFFERENTIAL PRESSURE SENSOR

BAPI’s ZPM is designed for quick and easy field installation. Output, range and other variables are quickly set in the field without powering the unit. LEDs on the face of the unit indicate when the pressure is low, in range or high for quick checks without accessing the BAS. Ranges and Outputs are set in the field for this unit rather than at the time of order.

10 Field Selectable Pressure Ranges and 5 Field Selectable Outputs
Ranges and Outputs Can Be Set Without Powering the Unit
Low, Standard and High Ranges Units
NIST Certificate Available at No Extra Charge
