SCHMIDT® Bluetooth® Verification Probe SS 20.450

Verify flow sensors on site

 

  • Simple, fast and safe verification of installed sensors – mobile on site
  • Easy-Clamp-On-Installation
  • Plug-and-Play
  • No additional power supply required
  • Radio module with Bluetooth® technology for transmission of the standard flow rate wN
  • Display and real-time recording of the measured values via the free SCHMIDT® Sensor App on a mobile Android end device – wirelessly, anytime and anywhere
  • Thermopile head (very fast response time)
  • Probe length 150 mm
  • Measuring ranges 0 … 1 m/s to 0 … 20 m/s
  • Cleanroom sensor

 

Particularly in cleanrooms or in clean processes, installed flow sensors should be verified on site from time to time. This can now be realised in the simplest way with the SCHMIDT® Bluetooth® Verification Probe SS 20.450.

 

The SCHMIDT® flow sensor remains in place and the Verification Probe is easily attached to the flow sensor using the metal clip supplied. The Verification Probe has a self-sufficient power supply and can therefore be operated completely wirelessly for up to 8 hours.

 

This makes it possible to check the sensor without having to remove it from the clean area and then clean it at great expense. The system operator can now verify the sensor with his SCHMIDT® Sensor App installed on the mobile Android device, have the real-time measurements displayed graphically on the smartphone or tablet and record the values (data logger function).
