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.
