The RS 1500-200 rotary position sensor from Macro Sensors, Pennsauken, NJ, measures 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 machine. It is available with a 24Vdc input and 0 to 10Vdc output (RSE 1500-120), or with a two-wire, 4 to 20mA loop-powered transmitter I/0 (RSI 1500-120).
The sensor utilizes contactless inductive technology to measure shaft angle position over a 120° nominal range, with linear error of less than 0.10% of full range output. It operates at temperatures of 0 to 185°F and meets IEC IP-66 standards. Other features include a servomount groove and pilot in the sensor body, splash-proof shaft seals, and mounting flanges.
