Setra SRPM Specifications

Model SRPM

Room Pressure Monitor

The SRPM is Setra’s standard single room BACnet capable
room pressure monitor for measuring low dierential pres­sure in critical applications. The SRPM’s backlit touchscreen
LCD provides an intuitive graphic user interface for ease of
setup. The SRPM has a built-in calibration feature and only
requires zeroing when installed, signicantly reducing the
cost of ownership. The SRPM monitors and alarms while pro­viding a digital input for a door alarm. The SRPM is a simple,
cost-eective solution which combines state-of-the-art elec­tronics with Setra’s superior true dierential pressure sens­ing technology to ensure safety in critical environments. The
SRPM also incorporates two-level password protection.

Monitor & Alarm Critical Rooms

The SRPM is most user friendly room pressure monitor on
the market today. It has an intuitive touchscreen interface
that allows the user to easily congure alarm set points,
passwords and audible alarming conditions. With its bi-di­rectional sensor, the unit can switch between protection and
isolation room modes, or be put into standby mode when
the room is not in use.

On-Board Dead-Ended Pressure Sensor

Protection and isolation rooms are designed to adhere to
strict standards in order to provide a proper barrier between
the room and reference space. Unlike a ow-through design,
the SRPM utilizes an on-board dead-ended low dierential
pressure sensor. This technology provides the user with a
trusted solution & peace of mind that the sensor will prevent
contaminated air from passing through it.

Save Time and Money on Installation & Calibration

The SRPM is designed with both the installer and end user in
mind. The BACnet enabled unit can be installed in an o-the­shelf electrical box, improving the ease of installation instead
of having to use a custom electrical box that is not typically
available at the rough stage of the project. The SRPM oers
push button zero and span calibration that is easily per­formed by any low dierential pressure calibrator and can be
calibrated in minutes.
