Series RPME Room Pressure Monitor

Room Status Indication, Magnehelic® Gage Size

The Series RPME Room Pressure Monitor is designed for low differential pressure applications that require stringent pressure monitoring and alarming. The Series RPME room pressure monitor can be configured to monitor positive or negative pressure in protected environments and clean manufacturing areas. The RPME room pressure monitor is a complete system with a fixed segment LCD which enables access to pressure, security, calibration, and alarm setup. The RPME has a brushed stainless steel bezel that allows for easy cleaning.

The RPME room pressure monitor has built-in status indication LEDs that will appear green when within the user-defined pressure set range and will appear orange when outside of the pressure set range. 2 SPDT independent control relays with adjustable deadbands are also provided along with a 4-20 mA process output.

For additional ranges, see Series DHC Digihelic® Differential Pressure Controller.
