CMR AIR MANAGEMENT SYSTEMS
Pressure and air volume monitoring and alarming
DPM Panel Pressure Monitoring Transmitter
The DPM pressure and velocity transmitter is just like the P-,V- or VP-
Sensor, it can measure low air pressure and air volume. It has also the
facility to provide a low and high alarm relay output. Time delays are
adjustable for both relays. Alternatively, one relay is used as low and
high alarm and the second relay is used to switch on the buzzer. A mute
facility shall cancel the second relay to mute the buzzer. It has a PID
control loop and two modbus rtu communications for a remote display
and the central BMS. All adjustments can be made from the front
keyboard. The DPM is calibrated to traceable national standard and
calibration certificates are supplied as standard.
DPM Pressure Transmitter
Central Monitoring Panel
CMR manufactures a stand alone monitoring panel which can contain
up to 30 DPM pressure or velocity transmitters. The colour coded PVC
tube can be pushed onto barbed nipples situated at the top of the panel.
The tubing can be configured to either measure room differential
pressure or individual room pressure against a common datum. Red
and blue PVC tube is normally used to measure the velocity pressure
across the CMR Velo Probes, Flow Grids, Oval Flow Probes or the
Venturi Ducts. The tube can run up to 200m and still have an accurate
measurement. The 0..10V, 4..20mA or modbus rtu and alarms can be
connected to any computer monitoring system. It is a compact
solution, which is factory tested and ready for installation on site. All
DPM instruments fitted come complete with calibration certificates.
Future calibration is easy as all equipment is centrally located in a plant
room and not within the clean areas or around the duct work.

CMR Portable Calibrator with Traceable Calibration Certificate
CMR manufactures manual portable and automatic calibrators, which
are used to check and calibrate any pressure or velocity pressure
transducers in the field. The most popular type is the CAL95 which has
a built in hand pump to generate the pressure for the transducers to be
checked. It has an LCD display to indicate the reference pressure. The
CAL95 has an output voltage signal which can be connected to a chart
recorder or computer scada system to record the calibration
pressures. The instrument is used by many commissioning and
controls engineers worldwide. The Calibrator comes with a traceable
calibration certificate.
