Pneumatic volume-flow controller

RLP 100

Pneumatic volume-flow controller

How energy efficiency is improved

Allows demand-based volume flow control for fume cupboards, laboratories and clean rooms


  • Suitable for use in potentially explosive atmospheres in zone 1 II 2 G T6

  • Conformity tested as per EN 13463-1 and EN 1127-1 (potentially explosive atmosphere 1 II 2 G T6)

  • Controls constant, switchable or variable air volumes

  • High-precision, static differential pressure sensor with large measuring range (1…160 Pa)

  • Front plate printed with circuit diagrams for easy identification of the controller functions

  • Compressed-air connections with Rp⅛” female thread

  • Special measuring connection for detecting the volume flow

  • Low-pressure connections with dual-diameter connector for soft plastic tubing (internal Ø 4 and 6 mm)

  • 2 inputs

    • Command variable

    • Setpoint shift Δ

  • 2 outputs

    • Actual value

    • Control of damper actuator

  • 1 adjuster for calibrating the sensor measuring range

  • 3 setpoint adjusters for maximum and minimum limitation of volume flow and for limiting the setpoint shift Δ to max. ±20%
