Macro Sensors has introduced its new RS 1500-120 series of fractional-turn contactless rotary position sensors for measuring the angular displacement of rotating elements; such as quarter-turn ball and butterfly valves, air flow dampers, and diverter gates used in packaging and postal sorting machinery. Available as the RSE 1500-120 with a 24 V dc input and a 0-to-10 V dc output (or as the RSI 1500-120 with a 2-wire 4-20 mA loop-powered transmitter I/O), these units are adaptable to a wide variety of industrial automation and process control applications.
Although their shafts can rotate a full 360º, the RS 1500-120 rotary position sensors utilise contactless inductive technology to measure shaft angle position over a nominal range of 120º with excellent accuracy and repeatability, and exceptional reliability. These units exhibit a linearity error of less than 0.10% of full range output, have an IEC IP-66 environmental rating, and operate at temperatures from 0ºF to 185ºF (-20ºC to 85ºC).
Other significant features of the RS 1500-120 series rotary position sensors include: servo-mount groove and pilot in sensor body; convenient mounting flanges available; splash-proof shaft seals available; no slip rings or rotors to wear out; absolute output so no output loss after power failure; and cost-effectiveness.
