FlowJam Plus - Features
38. PART OF THEENVEAGROUP
FlowJam A - Features
FlowJam A detects streams of solids of all types flowing at
a minimum speed of 0.1 m/s through the detection area.
The detection is independent of the direction of flow
through the Doppler effect evaluation system.
The flow of material through non-metallic pipelines is
displayed by two switching states on the output relay.
The sensor differentiates between the two switching
states:
• Material flow
• Material blockage or standstill.
