Calorimetric flow-sensor for gas SCHMIDT Technology
SS 20.60HT -> 350°C

SCHMIDT® Flow-Sensor SS 20.60 HT, for high temperature up to 350 °C

SCHMIDT Technology has developed a high temperature version of the SS 20.60 for the applica-tion in operating temperature up to 350 °C - for short time even 400 °C.
The sensor differs formally in the white ceramic tip. Most of the modifications have been made in-side the sensor and the modules are designed according to the elevated specification.
A complete new designed electronic unit processes the results of measurement and provides a digital and analogue output of flow velocity as well as temperature. The new status indicator dis-plays information about the current flow velocity and the sensors status. Due to the modular con-cept the unit can also be supplied with field bus interfaces. The sensors with field bus interfaces can calculate Kg/h or m³/min. and thus disburdens the supervising PLC. Additionally the sensor gives access to its status information and allows the PLC to inform the user about defects of the sensor.
Applications:
Mass flow-control of combustion processes, burner control, flow measurement of process gases, volume flow measurement of test stands, Measurement of flow velocity in drying plants and steril-izing processes.
