PRODUCT DESCRIPTION

The Hummingbird Panel Mount Cabin Pressure Monitor provides a highly visual readout to operators, letting them know when the cabin pressure drops below a critical level.

Low pressure in the cab can result in dust and other harmful materials entering the cab. High pressure can result in fatigue and headaches. The cab pressure monitor has been engineered for simple installation and operation.

The Cab 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, the display turns orange to alert the operator. After a user configurable number of seconds of the pressure being low or high, the display turns red, a warning is shown and the external outputs are triggered.

Powerfull Performance
The pressure measurement units and thresholds can be configured via a touch-screen. The touch-screen must be accessed within 10 seconds of power being applied after which it is disabled. The touch-screen also allows other features such as screen brightness, password and outputs to be configured.

A precision sensor allows pressure to measured to a resolution of 0.1mm H20. 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.
