The GHSDR 750 series of rugged spring-loaded DC-operated LVDTs are ideal for dimensional or position measurement in harsh industrial environments.
The GHSDR 750 series of rugged spring-loaded DC-operated LVDTs are ideal for dimensional or position measurement in automotive factories, forges and foundries (large shaft TIR measurements), metal fabricating shops, paper and/or plastic film plants, industrial process automation applications and all types of motion control systems.
Constructed entirely of stainless steel, the GHSDR 750 series has built-in electronics for a DC input/output operation.
Electronics and coil windings are hermetically sealed against hostile environments to IEC standard IP68.
The rugged construction of the GHSDR series permits operation in harsh industrial environments such as shop floors where dirt, oil, water and machine coolants may be present.
Electrical termination is made through a radially mounted sealed connector that permits a much shorter installed length.
The GHSDR 750 series offer three desirable features not typically found with comparable gauging-probe type position sensors.
The through-bore design allows for air purging of the sensor's bearings to remove any potential contaminants.
By locating the connector radially, the overall installed length of the LVDTs has been greatly shortened allowing for use in locations with space restrictions.
A detachable mating connector, supplied with every unit, permits repair or replacement of damaged or severed cables without the need to replace the entire LVDT, as with units having integral cables.
The GHSDR 750 units exhibit excellent performance with repeatability of 0.6um or better, and maximum linearity error of +/-0.25% of full range output.
Units are available in standard measurement ranges of +0.050, +0.125, +0.250, +0.500, +1.00 and +2.00in.
Special versions of the GHSDR 750 series of spring-loaded LVDTs can be provided for demanding or unusual applications such as nuclear radiation environments.
Liquid-tight electrical terminations can be easily added to standard units.
Operating from a +/-15V DC input, these position sensors provide a precalibrated 0 to +/-10V DC output that works in conjunction with many PLCs, digital indicators, A/D convertors, computer-based data processors, and QC data collection systems.
Macro Sensors manufactures a full line of support electronics for these LVDTs including OEM modules, DIN-rail mount line-powered and DC-operated signal conditioners and digital display and control instruments.
Pricing for the GHSDR 750 series begins at $545.
