Schmidt SS20.651 Flow Sensor

Schmidt SS20.651 Flow Sensor for measurement of flow velocity and / or volume flow at higher temperatures up to +350 °C . The temperature of the medium represents an important process parameter which can be used for monitoring or controlling. In combination with the measured mass flow this allows to calculate heat flow or heat flow volume. This sensor can be used in many applications with regard to energy efficiency, quantity detection and system control.

The Schmidt SS20.651 Flow Sensor is mechanically robust. The sensor uses a high temperature resistant ceramic substrate as carrier. This sensor element is positioned inside the aerodynamically designed chamber head, which is also made of heat-resisting ceramic material. The deposits and dust can be eliminated by cleaning the sensor elements with compressed air.

Advantages of the Schmidt SS20.651 Flow Sensor:

  • Direct measurement of standard volume flow up to +350°C and up to 16 bar
  • High turndown ratio of up to 1:300
  • Integrated temperature measurement
  • High precision calibration with ISO calibration certificate (optional)
  • Analog (2 x Auto U/I) and digital (2 x) outputs
  • Fieldbus output (optional)
  • Robust and compact housing
  • Two-color LEDs status display
  • Flexible probe lengths up to 1,000 mm and remote version (option)

On request the SCHMIDT® flow sensor SS20.651 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.
