LP 750 linear position sensors have a 3/4-in. diameter and are hermetically sealed to serve as long-life replacements for potentiometers. They are available in standard ranges of 4 to 25 in. and come with a pre-calibrated, loop-powered 4-20 input/output or nominal 24 Vdc input, 0 to 10 Vdc output. Maximum linearity error is ±0.25% of full-scale output. They suit long-stroke applications where sensor length must be as long as the stroke of the device.
