The BAPI ZPS-10-SR80-EZ-NT is a factory-configured EZ Pressure Sensor with a fixed 0 to 10 VDC output and a fixed -5.00 to 5.00” WC Bidirectional pressure range (range code SR80). Unlike the field-selectable EZ variants, the output and pressure range are factory-set, reducing commissioning to an auto-zero only — no switch adjustments needed in the field. Direction (uni/bidirectional) and units (inches WC or Pascals) remain field-adjustable. No pressure tube is included — connect your own tubing to the 3/16” barbed ports. The LCD display reads live pressure over the full operational range. Mounts on DIN rail, 2.75” Snaptrack, or surface. A NIST-traceable calibration certificate is available at no extra charge.
Fixed 0-10 VDC Output
Output is factory-set to 0 to 10 VDC — no rotary-switch output adjustment needed in the field. Power: 12 to 40 VDC or 9 to 28 VAC. Wiring: 3-wire via removable/pluggable terminal block (14–24 AWG).
Fixed SR80: -5.00 to 5.00” WC
Pressure range factory-set to -5.00 to 5.00” WC (bidirectional). Accuracy: ±0.25% FS • +/-0.025 in WC (+/-6.22 Pa). Total Error Band: +/-0.5% FS or +/-0.05 in WC (+/-12.44 Pa). Auto-zero via NEXT button after mounting. No range switch adjustment required.
DIN Rail / Snaptrack / Surface
Blue mounting tabs extend for DIN rail or surface, push in for 2.75” Snaptrack — no tools to switch modes. 3/16” barbed ports accept 1/8”–3/16” ID tubing. Pair with ZPS-ACC07 for a duct or plenum pressure tap. About 1/3 the panel footprint of field-mount sensors.

Frequently Asked Questions
What pressure range does range code SR80 correspond to?
SR80 specifies a factory-set standard range of -5.00 to 5.00 in WC (bidirectional). This range and the 0 to 10 VDC output are both fixed at the factory and cannot be changed in the field. Direction (uni/bidirectional) and units (inches WC or Pascals) remain field-adjustable via the rotary switch.
How do I auto-zero the ZPS-10-SR80-EZ-NT?
Connect the high and low pressure ports together using a short length of tubing without kinks. Set the rotary switch to the 0 position — the LCD display shows Aut0. Press the NEXT button; the display shows a series of progress bars, then donE for about 4 seconds. Return the switch to the desired pressure range. For critical applications, re-zero 2–3 times per year. Allow 24 hours unpowered acclimation and 60 minutes powered deadheaded before the first auto-zero.
What is the power requirement for the 0-10 VDC output on this unit?
The 0 to 10 VDC output requires 12 to 40 VDC or 9 to 28 VAC. For 4 to 20 mA output, the minimum voltage increases with controller input impedance: minimum voltage = (0.02 x load impedance in ohms) + 8. Example: with a 250 ohm input the minimum is 13 VDC. Connect power to the PWR terminal, controller input to the GND/4-20mA terminal (for current loop) or Voltage Out terminal (for VDC outputs).
