Spring-loaded position sensors

Edited by the Engineeringtalk editorial team Feb 6, 2007

Macro Sensors' line of 24V spring-loaded position sensors offer accurate position measurement with maximum linearity error of +0.10% of full scale output.

Macro Sensors has brought out a line of 24V spring-loaded position sensors that offer position measurement with maximum linearity error of +0.10% of full scale output.

Available in ranges of 0.100in (2.5mm) to 4.00in (100mm), the GHSE/GHSER 750 Series sensor comes in a ready-to-use package for position measurement in gauging applications.

Units can be installed in hostile environments, while their wiring is connected to power supplies, indicators and controllers located in remote, safe environments.

Units consist of a spring-loaded sleeve bearing that results in measurement repeatability of 0.000025in (0.6um) The spring-loaded assembly, along with a 0.5-20 threaded front end, makes mechanical set-up of the sensor into automated machinery less complicated and more cost effective than other sensor configurations.

Electrical termination of the GHSE 750 Model is made through a sealed axial connector and the electrical termination for the GHSER 750 is through a radially- mounted sealed connector for a much reduced installed length.

As an air extend, spring-retract unit, the probe shaft of Macro Sensors' GHSE/GHSER 750-A gauging probes fully extends when pressurised by air but retracts to get out of the way during unloading/unloading operations or to provide clearance for products on an assembly line.

Built-in electronics result in a position sensor that operates from DC inputs of 15-24V DC and generates a precalibrated 0-10V DC output.

The output from the GHSE 750 Series is designed to operate with most PLCs, digital indicators, data acquisition systems.

Units can be operated directly from a typical PLC's 24V power supply, providing added convenience on the shop floor.

Constructed entirely of stainless steel, these hermetically sealed 19mm diameter sensors provide long service life in various industrial uses such as industrial gauging systems, electronic dial indicators, fabricated metal products gauging, materials testing apparatus as well as large shaft TIR measurement.

Hermetically sealed LVDT-based gauging probes can withstand the effects of dirt, water, steam and other corrosive elements without effecting its performance.
