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 4-20mA 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 utilize contactless inductive technology to measure shaft angle position over a nominal range of 120º. 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 0F to 185F.
