TURCK's Linear inductive sensor

The LinearInductive sensor detects the position of objects through the use of a resonantpositioning device. An emitter/receive coil system generates a high-frequency alternating magnetic field that activates theresonator integrated into the positioning device. Each time thetransmitting coil stops transmitting, the resonator induces voltage into tworeceiving coils inteA-grated into the sensor. The voltage intensity depends onwhere the positioning device overlaps the receiving coils. An integrated 16-bitprocessor provides a corresponding proportional output signal in different formats:0 to 10V, 4 to 20 mA, IO-Link or SSI. TheLinear Inductive position sensor was designed to have extremely shortblind zones of only 29 mm on each side, along with a wide temperature range of-25 to 70C and the option to adopt the sensor by programming it to differentmeasuring ranges, allows users to dispense with special variants for specificapplications. Using only one sensor family for measuring ranges between 100 and1,000 mm simplifies warehousing and helps users reduce their total cost of ownership.UsingLI sensors for position detection is favorable over potentiometric ormagnetostrive devices due to their high accuracy (1 Amum) and mid-rangeprice-tag. Although there are several options for position detection - rangingfrom analog sensors, to incremental devices, to digital switches - not all ofthese can be easily applied to short-range and long-range applications. Also,unlike magnetorestrictive devices, TURCK's new Linear Inductive position sensordoes not use magnets. Magnetostrictiveand other similar technologies use magnets in their design that can experienceelectromagnetic interference in industrial environments.
