Bestech Australia has released Macrosensors RSE 1500 Series rotary position sensors.
The contactless, fractional-turn, absolute output rotary position sensors provide an analog voltage output proportional to shaft rotation over a total range of up to 120°.
They are designed for measuring the position of quarter turn ball and butter fly valves, flue dampers, weir gates, conveyor check weigher systems, dancer arm tensioners, and other applications involving fractional turn shaft movements.
The rotary position sensors are also useful for other limited rotation applications requiring high reliability like pedal position sensing for mobile equipment, or throttle lever position sensing in boats, cranes, and articulating-arm utility service vehicles.
This series of sensors use built-in electronics to offer DC input/output configuration.
They are available for ranges of 0° to 30°, 60°, 90° and 120° with a true-zero 0-10V DC unipolar output. Normal electrical I/O termination is a 5-pin M-12 connector receptacle.
The sensor is a full 360° rotation device, but the measuring range is marked, with the analog output increasing when the shaft is rotated clockwise in this range.
The units exhibit non-linearity of <±0.1% of the full scale output while operating in the compensated temperature range of -20°C to 85°C.
It also has a high tolerance for vibration and shock as well.
The rotary position sensor itself is enclosed in a 1.5 inch diameter anodized aluminium shell, and has a 0.25 inch stainless steel shaft running in high performance ball bearings.
