Schmidt SS20.500 Flow Sensor

SCHMIDT® Flow Sensor SS 20.500 offers an ideal solution for energy efficiency and complicated applications to include drying processes, exhaust discharge, glovebox and fume cupboard flows, volume flow control and many more. In addition to velocity the sensor also measures the process temperature
and both of these parameters are available as independent outputs. This combined measurement capability reduces the number of tapping points, easing installation and also offers an obvious cost benefit. Extreme flow angles of 360 degrees axial and ± 45 degrees from vertical simplify positioning in the gas flow. A wide measuring range of 0.06 up to 50 m/s and traceable calibration via a high precision adjustment ensures accuracy and reliability of measurement.

Schmidt SS20.500 Air and Gas Flow Switch

  • Unique sensor head resistant to dirt and air flow direction
  • Suitable for low velocity applications (full ranges within 0…1nm/s)
  • User adjustable setpoint (within range of device) via on board potentiometer
  • Local LED indication of switch position
  • Optional protective coating for aggressive gas media

The sensor is available with high precision adjustment. This option includes the supply of an ISO calibration certificate with recorded accuracy and repeatability. This calibration is carried out in house at Schmidt Technology with traceability to National Standards. A recalibration service is also offered.

Along with the thermal flow switch itself, Fluidic offer a full range of mounting and cable options from Schmidt to work with the SS20.500 flow switch.
