High Precision Rotary Position Sensors Measure Angular
Displacement of Rotating Elements

Rotary Position Sensors Measure Angular Displacement of Diverter Gates Used in Postal Sorting Machines

Pennsauken, NJ, June 8, 2009…

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 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
• 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.
