Mechatronic flow sensor for high temperatures

April 2014 Flow Measurement & Control

ifm electronic’s robust and maintenance-free SBT633 mechatronic flow sensor works on the principle of a spring-supported piston. The piston, located in the valve seat in the housing, is lifted against the spring resistance by the flowing medium. The piston position is monitored via a magnetic field sensor and is output as an analog signal.

Suitable for flow ranges from 0,3-25 l/min, the SBT633 has a 4-20 mA analogue output signal, a fast response and can be used for pressure ranges up to 15 bar.

The spring resistance forces the piston to return to its original position with decreasing flow ensuring position independent installation of the flow sensor, while at the same time, preventing backflow. Due to the temperature decoupling of the transducer from the electronics, this sensor is especially suitable for media in high temperature applications of up to 180°C.
