In line with this philosophy, Gefran Inc. is introducing a new model of magnetostrictive transducer specifically designed to provide a solution for pneumatics to the North America Market. Based on proprietary ONDA technology, the new ONPP-A transducer installs directly to the pneumatic cylinders surface and measures the position of the standard magnet integrated in the cylinder of all principal manufacturers.
The new ONPP-A was designed to solve one of the main problems with measuring magnets in pneumatic cylinders: recognition of polarity, which, depending on the magnet’s orientation, can cause an offset when reading its position. Due to a proprietary design developed by Gefran, the ONPP-A automatically performs recognition and consequent calibration, thereby eliminating any errors in position reading.
The system offers a series of other advantages: first of all, a smaller sensor performs the read of the entire cylinder stoke, reducing the size of the transducer as much as possible to the dimensions of the cylinder itself (according to ISO 15552). This makes the transducer especially suitable for coupling with pneumatic cylinders, as do other characteristics specifically designed for this application:
- direct installation on cylinder profile without brackets
- anodised aluminium body with extra-thin profile (thickness less than 1 cm)
- M8 radial connection
The transducer is available in strokes from 50 to 900 mm and has a direct analogue interface in voltage. Accuracy levels are optimized for pneumatic applications: resolution is infinite, linearity error is ± 0.2% (± 1 mm min.) of stroke, and repeatability error is 0.05 mm.
