LS120 air-gap sensor

2 to 33 mm range, −15 to 125 °C, 1.5 tesla.

The LS120 air-gap sensor is a high-quality, high-reliability air-gap sensor for use with an ILS730 signal conditioner, which provides voltage outputs and a current output.

The LS120 is designed and built for long-term use in extreme environments characterised by high temperatures and/or high-strength magnetic fields.
