Macro Sensors Introduces Contact-free DC-Operated Rotary Position Sensors Measure Angular Displacement of Rotating Elements up to 120º

Contact-free DC-Operated Rotary Position Sensors. Measure Angular Displacement of Rotating Elements up to 120º.

Pennsauken, NJ, August 05, 2010 --( Providing absolute output proportional to shaft rotation over a total range of up 120º, Macro Sensors RSE 1500 series of rotary position sensors are ideal for measuring the position of quarter-turn valves, flue dampers, weir gates, dancer arm tensioners, and a myriad of other applications involving fractional-turn shaft movements. These DC-operated rotary position sensors from Macro Sensors are also useful for high reliability applications such as pedal, throttle-lever, or actuator position sensing in aircraft, marine, construction, and agricultural vehicles.

Although their shafts can rotate a full 360º, the RSE 1500 Series Rotary RVDT Position Sensors measure shaft angle position over a nominal range of 120º. Sensors can operate in 0° to 30°, 60°, 90°, or 120° rotation ranges. Contactless inductive technology enables these rotary position positions to offer high accuracy and repeatability with exceptional reliability. Units exhibit a linearity error of less than 0.10% of full range output while operating over temperatures from 0ºF to 185ºF (-20ºC to 85ºC).

The RSE 1500 Series Rotary RVDT Position Sensors utilize built-in electronics to offer a DC input/output configuration. Operating from a nominal 24V DC power supply, units supply a true 0-to-10V DC output. The absolute output characteristic makes the RSE 1500 Series superior to incremental output sensors like optical encoders that lose their position information in the event of a power failure. Built for long life, units are enclosed in a 1-1/2 inch diameter anodized aluminum shell and have a 0.250” stainless steel shaft running in high performance ball bearings. The aluminum-mounting flange has a 0.750” diameter center pilot for locating centrally in a fixture. Units are also environmentally sealed to IEC IP-66.
