DESCRIPTIONAPPLICATIONS
The Series RPMC StabiliSENSE™ Critical Room Pressure Monitor
is designed for critical low differential pressure applications that require
stringent pressure monitoring and alarming. The Series RPMC can
be congured to monitor positive or negative pressure in protected
environments and clean manufacturing areas. The RPMC is a complete
system with a xed segment LCD which enables access to pressure,
security, calibration, and alarm setup. The StabiliSENSE™ critical room
pressure monitor has a brushed stainless steel bezel that allows for easy
cleaning.
The RPMC StabiliSENSE™ critical room pressure monitor has built-in
status indication LEDs that will appear green when within the user-dened
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.
