TURCK's Q25 Inductive Linear Sensor
Turck introduces a new high speed Q25 inductive linear sensor to the automation market. The internal measuring frequency is user selectable and can be as high as 5 kHz resulting in accurate measuring speeds of 5 meters per second. This high measuring frequency allows the Q25 to provide real time monitoring and measuring, resulting in more precise control. The Q25 inductive linear position sensors do not require a magnetic position device and are unaffected by metal debris commonly found in many industrial applications. The sensors provide high resolution and can be used to accurately measure lengths up to 1 meter.
TURCK's linear inductive sensor operation is based on the RLC resistance inductance capacitance principle. The sensors incorporate precisely manufactured printed emitter and receiver coil systems. The emitter coils are activated with a high frequency AC field and produce an inductive RLC circuit with the positioning element. The element is inductively coupled with the receiver coils, which are arranged so different voltages are induced in the coils, depending on the position of the actuator. The voltages serve as a measure for the sensor signal.
