OIS25
Optical smart sensor for hydraulic cylinders
General Description
OIS25 is a patented smart optical device, which is usually combined with a hydraulic steering cylinder. The main application is on rough terrain machines, to detect when the wheels are correctly aligned. The alignment occurs when the sensor detects a different refraction index zone, which is marked on the hydraulic cylinder’s rod.
The product is based on reflective sensor as input stage, a computing unit (microprocessor device) and an output stage with high side driver, which is able to deliver up to 150mA.
The sensor includes a lot of “smart” functions and special algorithms that allow to continuously adapt the device to the wear of the system during the time, improve the life of the system, guarantee the high reliability (MTTF = 103 years at 24V) and be able to work in the harsh environment (temperature variations, rod wear, presence of electromagnetic disturbs, presence
of humidity, shocks and vibrations). In addition, the particularity of this serie is that it provides diagnostic functions to auto detect possible failures. At every bootup the OIS25 is able to collect information about the functioning of the logic unit, of the output stage and of the sensor module.
