Macro Sensors is providing a line of spring-loaded AC/DC-operated LVDTs for dimensional or position measurement in a variety of industrial environments.
Constructed entirely of stainless steel, the GHSAR/GHSDR 750 series operates in harsh industrial environments such as shop floors where dirt, oil, water and machine coolants may be present.
Electronics and coil windings are hermetically sealed against hostile environments to IEC standard IP-68.
The GHSAR offers a through-bore design that allows for air purging of the sensors' bearings to remove any potential contaminants.
Electrical termination is made through a radially-mounted sealed connector that shortens the installed length of the LVDTs for use in locations with space restrictions.
A detachable mating connector is supplied with every unit for easy replacement of damaged cables.
These spring-loaded position sensors consist of a spring-laded shaft running in a precision sleeve bearing and connected to the LVDT core.
Use of a precision sleeve bearing results in excellent measurement repeatability of 0.000025 inches or better and maximum linearity error of 0.25 per cent of full range output.
Units are available in standard measurement ranges of 0.100" to 2.00" GHSAR 750 units operate from 3.0 Vrms (nominal) and can be connected to any standard LVDT signal conditioner, then passed to a gaging column display, digital recorder or computer-based data acquisition system.
GHSDR 750 units feature built-in electronics operating from a 15V DC input and provide a pre-calibrated 0 to 10 V DC output that works in conjunction with many PLCs, digital indicators, A/D converters, computer-based data processors and QC data collection systems.
Pricing for the GHSAR/GHSDR 750 series begins at $350.00.
