Typical Applications
Figure 9:
Duct Static Pressure Monitoring
(ZPM Pressure Sensor mounted on the duct
with a Static Pressure Probe in the duct.)
Figure 10:
Air Filter Pressure Drop
Monitoring (ZPM Pressure Sensor
mounted on the duct with a Static Pressure
Probe on either side of the filter in a duct.)
NOTE:
Best practice is to form a drip loop in the tubing to prevent condensation from reaching the ZPM.
Troubleshooting
POSSIBLE PROBLEMS:
LED does not light
LED is blinking fast
(1/2 second on, 1/2 second off)
Display is alternating between
a number and “err”
Output stuck (high or low)
Output not tracking pressure
properly
POSSIBLE SOLUTIONS:
- Check power connections for proper power
- The unit may be performing an auto-zero. Wait 10 seconds and check again.
- Sensor is in an Error Mode. Cycle power.
- The measurement is out of selected range.
- Remove pressure from ports and perform auto-zero procedure
- Check rotary switch for proper pressure range selection
- Check rotary switch for proper output range selection
