flow transmitter
 (dynamic shutter)

properties:

A thin, elastic blind, covering the entire flow cross-section, is
displaced by the flow of the liquid. There is a magnet on the blind generating
a changing magnetic field when the shutter is displaced. This field is detected
by a analog hall-sensor. Due to the elastic properties of the blind and a
moulded stop, even strong water impacts can be projected withstood.
The low quantity of parts coming into contact with the media guarantees low soiling
and reliable operation.

  • very fast response time
  • large overload security
  • measuring range 1:80!
  • low pressure loss
  • standardized signal output 4 to 20 mA (opional: 0 to 10 V)

area of application:
sensors suitable for: water
