20 to 60 mm range, ?15 to 125 °C, 1.5 tesla.
The LS121 air-gap sensor is a high-quality, high-reliability air-gap sensor for use with an ILS731 signal conditioner, which provides voltage outputs and a current output.
The LS121 is designed and built for long-term use in extreme environments characterised by high temperatures and/or high-strength magnetic fields.
