Press Release Summary:
Measuring angular displacement of rotating elements used in packaging and postal sorting machinery, fractional-turn RS 1500-120 series exhibits linearity error of less than 0.10% of full range output. Series includes RSE 1500-120, with 24 Vdc input and 0-10 Vdc output, and RSI 1500-120, connected as loop powered 2-wire 4-20 mA transmitter or 3-wire sourcing current transmitter using external 24 Vdc loop power supply. Both measure shaft angle position over nominal range of 120°.

Contact-Free DC-Operated Rotary Position Sensors Features 0.1% Linearity Over 120° Measurement Range
Pennsauken, NJ, October 11, 2007...Macro Sensors introduces 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 utilize contactless inductive technology to measure shaft angle position over a nominal range of 120° 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 185°F (-20°C to 85°C).
Other significant features of the RS 1500-120 series rotary position sensors include:
o Servo-mount groove and pilot in sensor body
o Convenient mounting flanges available
o Splash-proof shaft seals available.
o No slip rings or rotors to wear out
o Absolute output so no output loss after power failure
o Excellent price/performance characteristics
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 all kinds 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.
