Macro Sensors LVDTs: GHSER-750-006 METRIC Series Spring-Loaded Single-Ended DC-LVDT Position Sensors

Description

The Macro Sensors GHSER 750 Series of 19.0 mm 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. Electrical termination is through a radially mounted sealed connector, which results in a much reduced installed length. The mating connector plug is supplied with a unit. The through-bore design allows for air purging of the sensor’s bearings to remove potential contaminants.

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 0.6 ìm 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 precalibrated DC output. The output from the GHSER 750 Series are designed to operate in conjunction with many PLCs, digital indicators, A/D converters, computer-based data processors, and QC data collection systems.

Available in ranges of 2.5 mm to 100.0 mm, the maximum linearity error for a GHSER 750 Series sensor is ±0.10% of full range output using a statistically best-fit straight line derived by the least squares method.

For simplified mounting the GHSER 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.
