Optical single position sensors

Optical single position sensors measure a single point on the stroke of a hydraulic cylinder. They are integrated, tamper-proof, and insensitive to electromagnetic fields.
We have designed the optical position sensors specifically for agricultural and earth-moving machinery; the robust design of the sensors guarantees optimal operation even when the machines on which they are applied operate in harsh environments.

Operation and Applications

The main applications of optical single position sensors are centre or end-of-stroke measurement on steering cylinders, stabilisers, and telescopic cylinders. Unlike absolute position sensors, optical single position sensors measure a single point on the stroke of a hydraulic cylinder and thus pinpoint the exact position of the axle.

Optical Absolute Position Sensors

Optical absolute position sensors measure the stroke of a hydraulic cylinder. They measure the stroke with high accuracy of less than 0.1mm, are integrated and do not involve invasive mechanical work such as drilling into the piston rod. The main applications of these sensors are continuous measurement on steering cylinders, suspensions, and stabilisers.Features Simple to install and to replace Works with all rods diameters, no drilling Non-invasive, integrated and contactless Installable on passing through cylinders No calibration required Robust against EM noise and vibrations High reliability (MTTF = 180 years) Precise, accurate, resolute and repeatable Smart electronics with adaptive algorithms Several diagnoses onboard Range up to 1.5m

Level Sensors

Level sensors are optoelectronic devices based on emitters and receivers that work on the principle of reflection and refraction.The Optoi level sensor is based on optical prism technology which allows the light emitted by a LED to be captured by the receiver in the absence of liquid. On the other hand, in the presence of liquid, the optical channel is perturbed, thereby causing the absence of a signal on the receiver.Features Small size Simply installation Modular level sensing Robust optical technology High media compatibility
