About the Spring-loaded air actuated LVDT

The GHSAR 750-A Series of 3/4 inch diameter airextend/spring-retract AC-LVDTs are designed for a wide range of cycled position measurement and automated dimensional gaging applications where it is necessary or desirable to move the probe out of the way between readings. These 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. The contact tip supplied is an AGD standard number 9 made from black oxide hardened tool steel. It is fully interchangeable with other 4-48-threaded AGD contact tips. The combination of air actuation and a through-bore design allows for repeated purging of the sensor's bearings to remove potential contaminants.

For simplified mounting the GHSAR 750-A has a 1/2-20 UNF-2A thread on the front of the housing, permitting the user to install the LVDT in a mating threaded part or by using the two hex nuts furnished with the sensor. This results in a ready-to-use package for position measurements and longer range gaging applications.

Applications for GHSAR-A Series

  • Cycled measurement functions
  • Industrial gaging systems
  • Fabricated metal products gaging
  • Large shaft TIR measurements
