Bauma 2022

CAN sensor duo for mobile off-highway vehicles

From October 24 to 30, Elobau is part as an exhibitor at this year's Bauma. At booth 314 in hall A2, the Allgäu-based (Germany) manufacturer of sensors and machine safety, presents its generation of CAN-capable tilt sensors with the N6 static and the N7 dynamic.

The sensors are based on Mems technology and are designed for communication in a CAN system with the CANopen and J1939 protocols, each with or without relay switching output (Source: Elobau)

The N6 static enables high-precision measurement under harsh environmental conditions, in stationary operations or in the event of slow vehicle movement, explained the company in the official press release. For conversion, the sensor is backwards-compatible with the previous N3, N4, and N5 tilt sensors. A gyroscope is also integrated into the N7 dynamic, which enables measurement even in dynamic applications. Both sensors are suitable for use in off-highway vehicles, such as agricultural and forestry machinery, construction equipment, or industrial trucks.

These sensors come with IP67/IP6K9K protection (ISO 20653). They operate in a temperature range from -40° C to +85° C and are shock-resistant up to 50 g. The designers placed particular emphasis on measurement adaptability to the particular application, said the company. The sensors can be configured with various connections – Deutsch DT06-8S, one M12 5-pin or two M12 5-pin (CAN in/out). Networking the CAN signal (daisy chain) is possible in conjunction with the two M12 5-pin plugs and facilitates simplification of the cable harness, the company continued.

The N6 static and N7 dynamic tilt sensors are based on Mems technology and are designed for communication in a CAN system with the CANopen and SAE J1939 protocols, each with or without relay switching output. The N6 static also offers an analog signal with 4 mA to 20 mA or 0,5 V to 4,5 V.

Unified Diagnostic Services (UDS ISO 14229) expands the range of functions with a diagnostic option and software update. This enables parameter update capability and product selection.

The N6 static and N7 dynamic can be installed approximately 30 % faster than most other tilt sensors due to the 2-point mounting with M6 screws, claimed the manufacturer. Only a flat, sufficiently large surface is required for assembly, no further mechanical modifications are required, the company continued. By using the integrated connectors, the sensors can be adapted into existing cable harnesses.

The N7 dynamic is used when the vehicles are mainly exposed to uneven surfaces, vibrations, and shocks. The raw data from the acceleration sensor and gyroscope are combined using sensor fusion algorithms (Kalman filter). As a result, the N7 dynamic also delivers more stable and precise output signals while in motion than sensors without sensor fusion, the company ended the press release.
