High Precision Rotary Position Sensors Measure Angular Displacement

Pennsauken, NJ – The new RS 1500-120 series of fractional-turn contactless rotary position sensors from Macro Sensors measure 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 use contactless inductive technology to measure shaft angle position over a nominal range of 120º with excellent accuracy and repeatability and exceptional reliability. 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 a servo-mount groove and pilot in sensor body, no slip rings or rotors to wear out, absolute output so no output loss after power failure, and are available with mounting flanges and splash-proof shaft seals.

The RSE 1500-120 supplies a true 0-to-10 Volt DC output from a nominal 24 V DC power supply. The RSI 1500-120 rotary position sensor can be connected either as a loop powered two-wire 4-20 mA transmitter, or as a three-wire sourcing current transmitter using an external 24 V DC loop power supply. The voltage output version is a natural adjunct to PLC-controlled automation systems or PC-based data acquisition equipment. The 4-20 mA loop version supports a range of process applications with a low noise current loop output ideal for connection to the analog input of a remote data logger, supervisory process controller or SCADA system located some distance from the sensor or the measurement point.
