HVAC Filter Monitoring Application:
This example uses a GC30 differential pressure transmitter with 0 to 1.00 IWC range with two NPN
switches. The transmitter shall be programmed to activate the audible alarm when differential pressure
reaches 0.500 IWC with output 1 switch and to shut down the system if differential pressure reaches
0.750 IWC with output 2 switch by using external relays with normally open contacts for the audible
alarm and normally closed for the heating/cooling system. The outputs will reset at 0.200 IWC after the
filter is cleaned or replaced.
Installation:
Connect transmitter, relays, audible alarm and heating/cooling shutdown system per application,
diagrams below and manual instructions.
All specifications are subject to change without notice.
All sales subject to standard terms and conditions.
