Mobile vehicle

Mobile machinery such as construction, agricultural, and forestry machinery, as well as trucks or vehicles for recreational use

(like Segways), and the versatile range of electric vehicles are very demanding on the sensor due to their

external use.
Novotechnik sensors can be used in temperature ranges from -55 ° C up to +140 °C depending on the technology and design. They meet the standards in ingression protection up to IP 69K and are tested on the toughest requirements which surpasses

the pure standard specifications. This includes the simultaneous influence of temperature, humidity and liquids. A particular

focus is the robustness of the sensors against shock and vibration.
Due to the fact that the sensor unit is separated from the position marker, non-contact sensors can even be used for trans-

missive measurements. They are designed for high EMC protection to meet the requirements of mobile machines.
In the field of functional safety Novotechnik has  more than 10 years of experience as a supplier to the automotive industry,  especially in safety-critical applications.

Application:
Non-contacting angle measurment on the rotating axis of the rescue cage

Product:
Touchless Rotary Sensors, Series RFC4800

A typical example of the variety of hydraulic platforms and aerial ladders is the fully automated hydraulic turntable ladder with a platform height of 32 meters and an articulated work platform, which allows bending up to 75 degrees. However, in order to ensure a level platform, the boom angle has to be measured precisely. The specifications for the sensor, which is mounted on axis with the pivot point of the boom, are very tight. A sensor for this mobile application needs to be robust and electromagnetically compatible, as well as work properly in a wide temperature range. The sensor in this application needs to provide reliable measurement values even with existing mechanical tolerances and play in the joint bearing.


Application:

Actual value measurement at the steering angle


Product:
Absolut Linear Transducer, Series LAS

There is a trend in the automotive industry to transmit all driver input commands electronically. Electronic systems nowadays replace elaborate hydraulic system designs and improve ease of use as well as safety levels. Such smart solutions are only possible using reliable position sensors which survive the harsh environment in mobile applications and guarantee the required precision.  Steer-by-Wire systems find their way into construction and earth moving machines increasingly, for example as steering angle input devices or as actual position value devices on hydraulic actuators. Postion sensors can also monitor the safe and precise movement of  forks on a tractor.


Application:

Gear sensor / stabilize sensor


Product:
Non-contacting Rotary Sensors, Series RSC600

Potentiometric Rotary Sensors, Series SP2800

Sensors also find their ways into recreational vehicle applications, be it as a gear position sensor in an ATV or to "lean steer" a Segway Human Transporter.


Application:
Four wheel steering control

Product:
Potentiometric rotary sensor, series SP2800

Road sweepers have to be able to maneuver between parked cars, road works and a wide variety of other obstructions. The four-wheel steering reduces the turning radius for such vehicles.

Each vehicle is equipped with two potentiometric angle sensors series SP2800. They are fitted directly to the kingpins of one front wheel and one rear wheel. When the driver turns the steering wheel a microcomputer adjusts the relative front/rear wheel angles to provide optimum performance. He relies on the signal of the rotary sensor for the angle data.
