LVIT Linear Position Sensor

Long Lasting, Contactless, Inductive Sensors

The LR-19 series LVIT (Linear Variable Inductance Transducer) position sensors by Alliance Sensors Group are contactless devices designed for factory automation and a variety of industrial and commercial applications such as motor sport vehicles, automotive testing, solar cell positioners, wind turbine prop pitch and brake position, and packing equipment. With their compact device, superior performance, and excellent stroke-to-length ratio, the LR-19 sensors are ideal for both industrial testing, laboratories, and OEM applications.
LR-19 series sensors are offered in 6 full scale ranges from 25 to 200 mm (1 to 8 inches). Operating from a variety of DC voltages, these sensors offer a choice of four analog outputs and all include ASG’s proprietary SenSet™ field calibration feature. LR-19 series products are available with axial cable or connector terminations, or with radial exiting cable and two swivel rod eye ends for easy installation.
The LR series also include a larger body version, the LR-27, for those applications needing a heavier duty unit.
