EU-Konformitätserklärung (01/2024)
UK-Declaration of conformity (01/2024)

Thermal flow sensor with integrated electronics for measuring flow velocity of air, especially designed for monitoring laminar flow of air in cleanroom facilities.

  • Aerodynamically shaped dumbbell head with optimal flow properties, largely independent of direction
  • Cleanroom compatible design in accordance with GMP standard to prevent surface contamination
  • Operating status indication and serial number visible, even when sensor is installed
  • Flow and temperature signal
  • Probe length 300 … 1,000 mm (optional special length)
  • Probe length angled version: 150 / 270 mm x 300 mm
  • Measuring ranges 0 … 1 / 2.5 / 10 m/s
  • Vertical adjustment (for laminar flow applications, optional)
  • Coating (optional; sensor head only)
  • Cleanroom sensor

New: Now also in short design: 150 mm x 300 mm (angled)

Option: Monitoring of admissible speed interval (prescribed by official standards) of 0.45 m/s ± 20 % with optical signaling at the sensor (LF status indicator)

  • Laminar flow monitoring in cleanrooms
  • Process control in pharmaceutical, semiconductor technology and food industry
  • Use in isolators, flow boxes and sterile filling machines
