A series of contact-free linear position transducers have been introduced by ECEFast. These transducers operate on state-of-the-art Gefran ONDA magnetostrictive technology, maintaining durability and reduced expenses.
These devises are made up of an alloy body with sensors and all the essential electronics for generating 4mA to 20mA in proportion to the magnetic position along the body. The magnet can be integrated on a separate mechanical section, or on a moving carriage that drifts on the alloy body’s tracks.
Magnetostrictive Linear Position Transducer
The devise is operative on a current supply with 24VDC +/-20%. A maximum of 31 different sequences of calibrations can be performed from 0 to 50mm to 0 to 1500mm, based on the magnetorestrictive linear position transducers’ model. It exhibits a complete scale precision of 0.04%, and its relative velocity in the order of 10m/sec will not influence the calibration with respect to the sampling times ranging from 1 to 3 ms.
Gefran provides four varied range of magnetostrictive displacement transmitters having pneumatic and hydraulic cylinders. The ONP1-A sensors are IP65 certified and are operative at 75ºC, showing constant vibrational tolerance of 12g at 10Hz to 2000Hz. The ONP1-A is highly economical and shows enhanced performance, but is limited in electrical and output type interfaces. These position transducers are widely used in mechanical machinery encompassing cutting and shaping saws, plastic injection moulding machines, wood processing devices and presses.
