Magnetostrictive displacement transducer MPL - 1

MAGNOSENS Magnetostrictive Displacement Transducers Model series MPL: Analogue output or start/stop MPL 12475 DE 03 / 2016 ■ Measuring strokes from 50 to 2500 mm (analog.) respectively 3000 mm (start/stop) ■ Contactless, robust system ■ Infinite resolution ■ Unique reproducibility ■ Measurement signals 4 ... 20 mA, 0 ... 10 V or start/stop signal ■ Protection type IP 67 ■ Operating temperature range -40 °C ... +75 °C The displacement transducers operate according to the principle of run time measurement between two points of a magnetostrictive waveguide. One point is determined by a moveable position magnet, whose distance from the null point corresponds to the section to be measured. The run time of an emitted impulse is directly proportionate to this section. Conversion to an analogue measuring signal takes place in the downstream electronics. The waveguide is housed in an extruded aluminium profile. The electronics is housed in a die-cast aluminium sensor head. Electrical connection is implemented via a circular connector. The position magnet is located either in a slider, which is linked to the moving part of the machine via a ball joint, or it moves as a liftable position magnet, without wear, over the profile. Standard measuring strokes: (Other measuring strokes on request) □ < 500 mm in 50 mm steps □ > 500 - < 2500 mm in 50 mm steps □ > 2500 mm in 50 mm steps (only for output start/stop) Standard designs ■ Hysteresis: ■ Measuring frequency: ■ Temperature drift: ■ Op. temperature range: ■ Shock test: ■ Vibration test: ■ Protection type: < 4 pm Analogue: < 3 kHz, digital: depending on evaluation electronics < 40 ppm / °C - 40 °C to + 75 °C 100 g to IEC Standard 68-2-27 15 g / 10 to 2000 Hz to IEC Standard 68-2-6 IP 67 (with proper installed connector) Output signal The direction of the measurement signal must be specified on ordering. Subsequent changes to the direction of the measurement signal and setting the starting and end points are not possible.
