CERTEK Pressure Monitor (CPM Flush and Surface)

Product Description:

The CERTEK Pressure Monitor (CPM) can be used to monitor the pressure from room-to-room, within filter housings, and within duct. This Model #: CPM-10015-1 (Flush) is used in applications when the pressure monitor back box containing the components can be installed in the interior of a wall. This is normally accomplished during new construction, renovations, or if an existing wall is opened just to install the back box of this flush monitor. This monitor comes with a stainless steel flush cover with a lockable door and a 12”H x 12”W x 4”D steel back box. This Model #: CPM-10015-2 (Surface) is used in surface mounted applications when the pressure monitor back box cannot be installed in the interior of a wall. This is normally accomplished during renovations or in retrofit scenarios. This monitor comes with a hinged non-detachable cover from the 12”H x 12”W x 4”D surface box. The surface box with cover is made of steel with a baked enamel gray coating.

Flush - A bi-directional digihelic gauge with a large screen and buttons for adjusting the gauge’s settings is installed in the center of the flush cover’s hinged door. The range of the gauge is dependent upon the application. The door is opened with a key for easy access to the inside components.

Surface - A bi-directional digihelic gauge with a large screen and buttons for adjusting the gauge’s settings is installed in the center of the surface box’s hinged cover. The range of the gauge is dependent upon the application. The door is opened by a slotted keyless closer for easy access to the inside components.

Status lights for normal and alarm with an audible alarm buzzer and silence pushbutton is visible on the front of the cover. A port for pressure monitoring to the gauge is also located in the front hinged cover. A 24” length by ¼” diameter hose for sensing pressure is provided penetrating the side of the box with sufficient support to prevent crimping or damage to the hose. Sufficient length for through-the-wall monitoring of the room to be monitored is provided, or additional length can be added by the installer to monitor housings and duct. One set of dry contacts are provided for remote monitoring.

Static Pressure Monitor (SPM)

Product Description:

The Static Pressure Monitor (SPM) is used to monitor the duct pressure while located near a Glovebox or Biological Safety Cabinet. There are two control panels to make this system function properly. One is located by the glovebox and/or BSC for visual and audible monitoring (Display Control Panel) and the other is located near the duct (Sub Panel), usually in an accessible ceiling or mechanical room. The Display Control Panel located at the glovebox and/or BSC also has a fan control button to turn the fan on and off. The Sub Panel located in the accessible ceiling or mechanical room is where the pressure hoses terminate on a pressure switch and a differential pressure transmitter. This box contains most of the components of the system.

The SPM is designed for researchers at the primary level of containment of gloveboxes and BSC’s in a Bio-Safety Level III laboratory to be able to monitor the duct pressure and control the fan. The fan can be turned on at the beginning of a task and off when not in use. The display is programmed with large white numbers on a black background to reflect the pressure. Also, located on the stainless steel cover of the Display Control Panel of the SPM is an audible and visual alarm and a push-on push-off button control for the fan.

The Display Control Panel comes with a stainless steel flush cover and 8”H x 8”W x 4”D flush mounted steel back box with back plate. There is an option for a surface mounted Display Control Panel. The surface panel comes with a hinged non-detachable cover from the 10”H x 10”W x 4”D surface box. The surface box with cover is made of steel with a baked enamel gray coating. The control panel near the duct for the flush or surface mounted Display Control Panel comes with a blank steel cover and 10”H x 10”W x 4”D steel back box with back plate.

Features:

  • Primary Voltage: 100-240 VAC, 50/60 HZ
  • Secondary Voltage: 24 VDC
  • 1 and 2 Amp Circuit Breakers
