Use

The Dust Alarm 40 was specially developed to monitor clean sides after filters reliable and without time delay regarding filter breaks. The sensor can be used in metallic channels where dust particles are to be detected in the gas stream at dust concentrations of 1 mg/m3 up to 500 mg/m3.

The Dust Alarm 40 can also be used in hazardous areas (dust zone 2/ gas zone 2).

Function

Dust Alarm 40 uses the electrodynamic measurement principle. As soon as particles pass or strike the probe, a charge transfer takes place.
From this, a measuring signal is generated which triggers a switching contact at a given limit value or is available as a current output.

The Dust Alarm 40 consists of a sensor and a control unit. The simple, icon-driven menu provides users with a language-free setup and system overview.
With a 2,8” color display the correct function of the filter or an exceeding of the limit value are displayed visually during operation.
In addition, the Dust Alarm 40 comes standard with two independent relay outputs and an optional 4 … 20 mA output.
