LVDT AC Spring Loaded GHSA 750 Series of 3/4 inch diameter Macro Sensors

The Macro Sensors GHSA 750 Series of 3/4 inch diameter spring-loaded AC-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. Electrical termination is through a axially mounted sealed connector.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 0.000025 inches (0.6 µm) or better. The output from the LVDT can be connected to any standard LVDT signal conditioner and then passed to a gaging column display, digital readout, or computer based data acquisition system.

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.

Available in ranges of ±0.050 inch (±1.25 mm) to ±2.00 inches (±50.0 mm), the maximum linearity error for a GHSA 750 Series sensor is ±0.25% of full range output using a statistically best-fit straight line derived by the least squares method.

For simplified mounting the GHSA 750 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.

All GHSA 750 Series LVDTs will operate properly with any conventional differential input LVDT signal conditioners, but operation with ratiometric LVDT signal conditioning is not recommended. Macro Sensors offers a full line of LVDT signal conditioners that will deliver optimum performance from any GHSA 750 Series LVDT. Details can be found in series 9000 technical bulletins.
