About the Spring-loaded LVDT DC operated position sensor
The GHS 750 Series spring-loaded LVDTs are designed for a wide range of position measurement and dimensional gaging applications. These rugged, 3/4 inch diameter, hermetically sealed sensors are constructed entirely of stainless steel and are available in ranges of 0.100 inch (2.5 mm) to 4.00 inches (100 mm). The maximum linearity error for a GHS 750 Series sensor is ±0.10% of full range output. Units are supplied with built-in electronics for either DC operation with a pre-calibrated 0-10VDC output (GHSE) or 4-20 mA current loop operation (GHSI).
The sensor consists of a spring loaded shaft running in a precision sleeve bearing and connected to the core of the LVDT. The probe shaft is fully extended by a spring (k=0.23 lbs./in.), exerting a nominal force of 6 to 20 ounces depending upon total range. The hardened tool steel contact tip is an AGD standard number 9 and is fully interchangeable with other 4-48-threaded AGD contact tips. For simplified mounting, GHS sensors have a 1/2-20 UNF 2A thread on the front of the housing and are supplied with two hex nuts.
An air-extend/spring-retract option allows for a wide range of cycled position measurement and automated dimensional gaging applications. The shaft is extended by introduction of a low-pressure (10-40 psi), clean, dry air supply, with a regulated flow, through a barbed fitting on the end of the unit for 1/4 inch I.D. hose. With the release of pressure, an internal spring returns the probe to its retracted position.
