1. 1 Intended use
The Setra SRIM Room Isolation Pressure Monitor is designed for critical low differential
pressure applications that require stringent pressure monitoring and alarming. The SRIM can
be configured to monitor positive, negative or neutral pressures in protected environments.
The SRIM is a complete system that includes a 2 line LCD display with large characters for
the pressure, temperature and humidity indication and room status. The membrane keypad
user interface enables access to setup, security, calibration, and alarm setups. Backlight
LED’s (SRIM2) provide a local visual indication of the room pressure alarm status and a local
audible alarm (with time delay feature) alert personnel to system status. Analog outputs are
available in 4-20 mA, 0-5 or 0-10 VDC in the same unit. True differential pressure is displayed
with a resolution of up to .0001” as well as the room status. Setra’s patented very low pressure
capacitance sensor is dead ended and avoids the potential for cross contamination of the room
and reference space as well as eliminating drift that results from fouling of flow based sensors,
which by nature have a flow path connecting the protected and reference spaces.
2.0 SRIM included parts
The SRIM parts list includes:
• SRIM isolation room monitor
• Electrical plugs for ½” conduit or PG9 strain relief connector.
• RPS pressure taps 0, 1 or 2 as ordered, including mounting screws.
The RPS is mounted to a single gang box. One is typically located in the isolation room and the
second is mounted in a corridor (reference pressure). The back of the RPS has a barbed fitting
for plastic tubing to be connected to the SRIM.
