Dwyer Instruments StabiliSENSE RPMC Series Specifications-Installation And Operating Instructions

Series RPMC StabiliSENSE
Specifications - Installation and Operating Instructions
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 configured to monitor positive or negative
pressure in protected environments and clean manufacturing areas. The RPMC is
a complete system with a graphic user interface which enables access to pressure,
security, calibration, and alarm setup. The RPMC StabiliSENSE
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 between 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.
FEATURES/BENEFITS
• Long term stable pressure measurement
• 2 SPDT relays allow for capability of local alarming and alarming to control system
• Automatic or manual alarm reset
• Visual LED alarms provide immediate local alert allowing corrective action to be
taken quicker to eliminate the problem from becoming widespread
• Stores peak and valley process readings
• Same installation diameter as Magnehelic
RPMC StabiliSENSE critical room pressure monitor
™
• Password protected setup menu ensures no errors by untrained personnel
INSTALLATION LOCATION: Select a clean, dry location free from shock and vibration
where temperature limits will not be exceeded. Distance from the transmitter to the
receiver is limited only by total loop resistance. See ELECTRICAL CONNECTIONS.
Tubing feeding pressure to the instrument can be practically any length required, but
long lengths will increase response time slightly.
POSITION: All standard models are calibrated for use in a vertical mounting position.
Standard models will perform properly at other angles but should be spanned and
zeroed in the position in which they will be used. WARM-UP: It is recommended to
power up the RPMC StabiliSENSE
™
taking measurements. This will stabilize the measurements and provide the best
accuracy.
PRESSURE CONNECTIONS: For installation convenience two sets of 1/8˝ female
NPT pressure ports are supplied. Be sure to seal the unused ports with pipe plugs,
included.
Positive Pressure - Connect tubing to HIGH PRESSURE port and vent LOW
PRESSURE port to atmosphere.
Negative (Vacuum) Pressure - Connect tubing to LOW PRESSURE port and
vent HIGH PRESSURE port to atmosphere. (When operating this device in a dusty
environment, install an optional A-331 Filter Vent Plug in the vented port to keep
interior clean).
Differential Pressure - Connect tubing from the higher source to HIGH PRESSURE
port and from the lower source to LOW PRESSURE port.
