SPRING LOADED AIR ACTUATED LVDT

The GHSA-R 750-A rugged, hermetically sealed sensors are constructed entirely of stainless steel and intended for general industrial use.  The coil windings are sealed against hostile environments to IEC standard IP-68. Electrical termination is through a radially mounted sealed connector, which results in a much reduced installed length. The mating connector plug is supplied with the unit. The sensor consists of an air-extend/spring-retract shaft running in a precision sleeve bearing and connected to the core of an LVDT. The shaft is extended by introduction of a low-pressure (10-30 psi), clean, dry air supply, with a regulated flow, through a barbed fitting on the end of the unit for ¼ inch I.D. hose. With the release of pressure, an internal spring returns the probe to its retracted position. The use of a precision sleeve bearing results in measurement repeatability of ±0.01% of full range output or better.
