Transcript of Mechatronic flow sensor for high Fluid sensors and ...Measurement of liquids up to 180 C. Process...
Measurement of liquidsup to 180 °C.
Process cooling in an induction furnace.
Mechatronic flow sensorThe flow sensor works to the principle of spring-support-ed piston: the piston, located in the valve seat in thehousing, is lifted by the flowing medium against thespring resistance. The piston position is monitored via amagnetic-field sensor and is output as an analogue signal.The spring resistance forces the piston to return to itsoriginal position with decreasing flow. This ensures posi-tion-independent installation of the flow sensor preven-ting backflow.Due to the temperature decoupling of the transducerfrom the electronics, this sensor is especially suitable formedia in high temperature applications of up to 180 °C.The units are maintenance-free.
