产品介绍

The Macro Sensors GHSTAR 750 系列 of 3/4 inch diameter spring-loaded AC-LVDTs are designed for a wide range of position measurement and 尺寸al gaging 应用领域. These rugged hermetically sealed sensors are constructed entirely of stainless steel and are intended for use at high temperatures (400°F) or exposed to mild radiation (3x107 Rads). 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 0.000025 英寸 (0.6 ìm) 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 标称 force of 6 to 20 盎司 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 英寸 (±50.0 mm), the maximum 线性误差 for a GHSAR 750 系列 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 GHSTAR 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 应用领域.

All GHSTAR 750 系列 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 GHSTAR 750 系列 LVDT. Details can be found in 系列 9000 technical bulletins.
