Functional description

The sash distance is recorded with a draw wire that is linked to the sash movement. The output signal is proportional to the sash distance. The sensor can be used only with vertical sashes.


DS-TRD for fume cupboard control – linear control strategy

  • EASYLAB controller TCU3: Equipment function FH-DS


  • Variable volume flow control based on the measured sash distance
  • Volume flow rate is linear to the sash position: OPEN corresponds to Vmax, CLOSED corresponds to Vmin
  • Sash opening can be monitored according to EN 14175, without additional switch contact


DS-TRD for fume cupboard control – safety-optimised control strategy

  • EASYLAB controller TCU3: Equipment function FH-DV


  • Safety-optimised volume flow control based on the measured sash distance
  • The volume flow rate is linear to the sash distance; the aim is to maintain a constant safe face velocity (0.5 m/s) even if the sash is fairly wide open
  • Sash opening can be monitored according to EN 14175, without additional switch contact

Installation and commissioning

  • Fix the sash distance sensor to the fume cupboard
  • Link the measuring wire to the sash movement, e.g. by fixing it to the balance weight of the sash
  • The measuring wire can be drawn vertically or horizontally.
  • Measuring range 0 – 1750 mm or 350 – 2100 mm
  • The controller automatically recognises the sash distance sensor
