SCHMIDT Duplex-Laminar-Flow Sensor SS 20.415 Twin

The SCHMIDT Duplex-Laminar-Flow Sensor SS 20.415 Twin for double validation of laminar flow. The combination of two completely self-sufficient flow sensors made it possible to realize a redundant flow measurement at the same measuring position and to eliminate the mutual influence of the two probes. Both flow signals are delivered separately from one another via two analogue outputs.

Advantages of the Schmidt SS20.415 Twin Flow Sensor:

  • Redundant validation of laminar flow applications
  • Two independently working high-nd flow sensors in one unit
  • Easy installation at one measuring point
  • No mutual influence of the measurement
  • Confined space becomes a minor matter
  • Plug and Play and quick assembly
  • Precise measurement of low flow velocitie[wN]
  • Straight and angled design for wall ceiling mounting
  • Thermopile head (very fast response time)
  • Probe length straight version: 300 mm
  • Probe length angled version: 150 / 270 x 300 mm
  • Measuring ranges 0 … 1 m/s to 0 … 2.5 m/s
  • Cleanroom sensor
  • Extremely compact, because electronics are integrated into the sensor tube
  • Sensor element in the chamber head and protected against mechanical stress
  • Linear analog output for measured value output
  • Special version for the laminar-flow monitoring in cleanrooms via quick-mounting system for simple installation in cleanroom ceiling systems and walls. 

On request the SCHMIDT® flow sensor SS20.415 can be delivered with an ISO calibration certificate which documents the high accuracy and reproducibility of flow measurement on the basis of real measuring values and deviations.
