The inclination of a mobile machine can be decisive in many applications. Tipping over must be avoided in any case. The new inclination sensors of the JD series from ifm electronic can help here – even under difficult conditions. At BAUMA, the biggest trade fair for construction machinery in the world, ifm electronic presented their new dynamic inclination sensors of the JD series. They are for example used for the detection of inclination angles and positions of mobile machines. Typical applications are the horizontal levelling of platforms or the boom measurement on wheeled excavators. Especially for mobile machines conventional inclination sensors often reach their limits. Vibration, impact or external acceleration of the machine, which may occur during starting orbraking, may lead to faulty measured values. The inclination sensors of the JD series do not have this problem. They use a 3D gyroscope as well as a 3D acceleration sensor. A 6-axes IMU (Inertial Measurement Unit) with intelligent sensor fusion filters determines the precise inclination values on this basis.

The data of the gyroscope correct the infl uences caused by acceleration, vibration or impact. This is why the quality of the signals provided by the JD sensors is very high even under extreme environmental conditions. Different versions of the new inclination sensors are available so that they can be mounted horizontally as well as vertically.

They reach a static precision of ±0.3° and a dynamic precision of ±0.5° in moving systems. The inclination sensors of the JD series have a robust housing made of aluminium injection moulding. They are shock-resistant up to 100 g and meet the IP67 and IP69K protection ratings. Together with the wide operating temperature range from -40°C to 85°C they can be used under extreme conditions and always provide precise measured values. An integrated CANopen interface is used for the transfer of the measured values and also for the parameter setting of the sensors. If required, an integrated terminating resistor can be activated via software.
