Macro Sensors_HSI 750_WEB.jpgMacro Sensors announced the HSI/R 750 Series of hermetically sealed, loop-powered 4 mA to 20 mA position transmitters for a wide range of position monitoring and feedback applications. Units are designed for mechanical position measurement where a hard connection can be made to a test piece. The 4 mA to 20 mA current loop input/output of these rugged and robust devices enables easy field integration with PLCs, digital indicators, host computer-based data processing, and QC data collection systems.  Units can be configured for either loop-powered, two-wire or externally powered three-wire sourcing output to address different I/O requirements in various applications. Constructed entirely of TIG welded stainless steel and hermetically sealed against hostile environments to IEC standard IP-68, LVDTs can be installed in hostile environments while the loop wiring connects to remote indicators and/or controllers located in environments safe from hostile conditions. Units offer precise output with a maximum linearity error of 0.25 percent of full range output or better using a statistically best-fit straight line derived by the least squares method.  For more precision measurement the HSI/R series is also available with ±0.10 percent linearity.  Available in full ranges from 0.10” (2.5 mm) to 20” (500 mm), these ¾” (19 mm) diameter LVDTs are available as either blind bore units (HSI 750 Series) terminated in a glass-sealed axial or in a through-bore design (HSIR 750 Series) with the connector mounted.
