For mobile machines
The JD series sensors from ifm Electronic (Germany) measure inclinations in harsh environments and provide the data via a CANopen interface. The company also offers the CANwireless gateway allowing a Wifi or a Bluetooth connection to the CAN network in a machine.
The sensors embed a 3D-gyroscope as well as a 3D-acceleration sensor. A six-axes IMU (inertial measurement unit) with sensor fusion filters determines the basis inclination values. The data of the gyroscope corrects the influences caused by acceleration, vibration, or impact. The devices reach a static precision of ±0,3 ° and a dynamic precision of ±0,5 ° in moving systems. The integrated CANopen interface complies with the CiA 410 application profile for inclinometers. It is used for transfer of the measured values and for sensor parameter setting. An integrated terminating resistor may be activated via software. The IP67 or IP69K protected devices with aluminum housing may be mounted horizontally or vertically. The sensors with the operating temperature range from -40 °C to +85 °C are designed for detection of inclination angles and positions of mobile machines. Typical applications are horizontal levelling of platforms or boom measurement on wheeled excavators.
The CANwireless gateway allows wireless access to the CAN interface of mobile machines e.g. via a PC or a mobile end device. Thus, programming, data exchange, and diagnostics is possible without a cable connection using company’s existing tools such as Codesys or the Maintenancetool. As protocols the CAN data link layer, CANopen or J1939 are supported. The CAN receive buffer and the CAN-to-Wifi buffer are respectively sized up to 2048 messages. The IP protection of IP65 (external antenna) or IP67 (internal antenna) as well as the temperature range of -40 °C to +85 °C enable the device usage in harsh environmental conditions.
