Snifter dust switch

February 2008 Operator Interfaces, Switches & Relays

The stainless steel Snifter dust switch is used to detect filter bag breakage quickly and cost-effectively and applies the triboelectric AC signal principle. Fast response makes it suitable for the requirements of bag filters and it can also be used for process control in flow/no-flow applications in bulk solids handling and pneumatic transport applications.

Features include:

* Solid particle detection in gas flow down to 0,3 μm.

* Gas velocity with a minimum of 4 m/sec.

* Two solid state relays.

* IP65 rating.

* 12–24 V d.c. operation.

* Self adjustment with zero drift.

The device finds application in areas such as:

* Food and beverages.

* Filter manufacturing.

* Chemicals and pharmaceuticals.

* Petrochemicals.

* Steel and other processing industries.
