These linear position sensors for precise, repeatable measurements in metal processing machines do not use magnetic sensors.
Turck‚ LI-Q25 series linear position sensors use emitter and receiver coil systems, precisely arranged on a printed circuit board, that are activated with a high frequency AC field and produce an inductive RLC circuit with the positioning element (resonator). As a result, the resonator is inductively coupled with the receiver coils. Different voltages are induced into the coils depending on the position of the resonator, and these voltages serve as a measure for the sensor signal. This technology replaces magnetostrictive and potentiometer devices thus are unaffected by metal debris. The sensors provide up to 1 µm resolution and can achieve measuring ranges between 100 and 1,000 mm with analog voltage/current, SSI or I/O Link outputs.
To increase the speed and accuracy of measurement, LI-Q25 series linear position sensors have a coarse and a fine measuring coil system that is microprocessor controlled. An integrated processor provides an output signal in different formats: 0 to 10 V, 4 to 20 mA, IO-Link or SSI.
The linear position sensors have extremely short blind zones of only 29 mm on each side, along with a wide temperature range of -25 to 70 C. The sensors may also be programmed for different measuring ranges.
