Units 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.
