The Configurable Cabin Pressure Monitor measures pressure in the cab and compares it with atmospheric pressure. When the pressure in the cab drops to a level that is not high enough to prevent dust and other materials entering the cab, a green light on the unit turns red. As long as the pressure is low, a normally high output goes low allowing interface to external units.
High-pressure events are also monitored. Using an internal rotary switch the Cabin Pressure Monitor can be configured to alarm at low pressures between 10Pa and 90Pa (1mm to 9mm H20). Based on customer feedback, the cabin pressure alarm is supplied pre-set to 50Pa (5mm H20) low pressure and 300Pa high pressure.
A precision sensor allows pressure to measure to a resolution of 0.1mm H20. The measured pressure is temperature compensated to allow operation over a wide range of temperatures. An extremely high sensor burst pressure of 5000Pa means that door slams will not affect the sensor.
Push fittings allow for quick installation of the tube to the outside. A spare bulkhead push fitting is provided to enable sealed entry through the vehicle firewall if required. Mounting slots are provided on either side of the enclosure
