FlowSwitch FS 550M

The sensor can be installed in pipelines, on conveyor belts, on drop plates, on chutes, behind screws or in similar conveying equipment. It enables reliable detection of the material flow and detects insufficient or missing material, clogging or standstill – from a distance of several meters. It does not come into contact with the bulk material and is wear- and maintenance-free.

Product Description
Technical Data

Function

The FlowSwitch FS 550 is based on the latest microwave technology. When a material passes the sensor, the emitted microwaves are reflected. This is converted into a flow-proportional output signal for trend measurement. The sensor can be installed in pipelines, on conveyor belts, on drop plates, on chutes, behind screws or in similar conveying equipment.

More info

It enables reliable detection of the material flow and detects insufficient or missing material, clogging or standstill - from a distance of several meters. It does not come into contact with the bulk material and is wear- and maintenance-free. Numerous parameters, such as sensitivity and filter time, are adjustable, and the sensor can be easily adapted to any application.

The FS 550 is known as the most robust flow switch in its class. It is constructed of high quality stainless steel and is optimized for long life. High pressure adapter allows use in the most challenging environments.
