Mechatronic sensors for internal drill cooling
The mechatronic flow sensors of the SBU series monitor liquid media such as water, glycol solutions, industrial oils or coolants. They are mostly used to monitor the internal drill cooling on machine tools.
The sensors operate to the principle of spring-supported piston. The piston, located in the valve seat in the housing, is lifted by the flowing medium against the spring resistance. The position of the piston indicates the flow. The spring resistance forces the piston to return to its original position with decreasing flow, preventing backflow.
Thanks to its robust mechanical design, the sensor can be used at high pressures and in harsh industrial environments. The product line comprises flow transmitters with analogue output and flow monitors with switching output. The switch points of the flow monitors can be set and fixed via a setting screw.
