Position sensors deliver loop-powered operation

Keywords:sensors? operation loop powered? position Macro?

Macro Sensors has introduced a DC-operated position sensor that is spring-loaded and offers a two-wire, loop powered 4-20mA operation commonly used with current-operated process controllers and recorders. Built-in loop powered electronics result in a position sensor that operates from a DC input and generates a 4-20mA output that interfaces with many PLCs, computer-based data processors, and QC data collection systems.

Operating over a wide range of loop supply voltages and with loop resistances up to 800?, the GHSI 750 series position sensors are suitable for use in machine tool inspection, go/no/go inspection, and statistical quality control info or as part of a closed-loop control system. The position sensors are also for remote sensing applications in which AC power is not readily available to operate external signal conditioning.

Hermetically sealed and constructed entirely of stainless steel, the coil windings are sealed against hostile environments to IEC standard IP-68. These position sensors can be installed in hazardous locations while the wiring connected to power supplies, indicators and controllers are in a safe environment.

Available in ranges of +.100-inch (+2.5mm) to +4.00-inch (+100mm), the maximum linearity error for a GHSI 750 series position sensors is 0.10 percent of full range output using a statistically best-fit straight line derived by the least squares method. Price starts at $594.00.
