About the Spring-loaded DC-LVDT position sensor

The GHSD 750 and GHSDR series of 3/4 inch diameter spring-loaded DC-LVDTs are designed for a wide range of position measurement and dimensional gaging applications. 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. The electrical termination for the GHSD is through a sealed axial connector. The GHSDR electrical termination is through a radially mounted sealed connector, which results in a much reduced installed length. The throughbore design allows for air purging of the sensor’s bearings to remove potential contaminants. The mating connector plug is supplied with the unit.

The sensor consists of a spring loaded shaft running in a precision sleeve bearing and connected to the core of an LVDT. The use of a precision sleeve bearing results in measurement repeatability of 0.01% of full range or better. The probe shaft is fully extended by a spring exerting a nominal force of 6 to 20 ounces depending upon total range. The contact tip supplied is an AGD standard number 9 made from chrome plated hardened tool steel. It is fully interchangeable with other AGD contact tips.

Built-in electronics result in position sensors that operate from a DC input and generate a pre-calibrated DC output. The output from the GHSD 750 and GHDSR series is designed to operate with many PLCs, digital indicators, A/D converters, computer-based data processors, and QC data collection systems.

For simplified mounting the LVDT 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.
