The hermetically sealed devices offer contactless position measurement for applications such as vane-pitch servocontrols, fuel-valve position feedback, governor controls, shaft end play and runout, and generator shell-expansion measurement. Features of the sensor include full-scale measurement range of ±1 to ±10 in.; high resolution; repeatability better than 0.01% of full scale; nonlinearity of less than 0.25% of full range output; and through-bore design for accessibility from both ends as well as to facilitate bore cleaning. Lead wires exit through a radially mounted NPT male rigid conduit fitting for easy attachment to an explosionproof junction box. Temperature range of the stainless-steel LVDTs is 65 to 300°F.
