Encoders, Cable-Pulls & Inclination Sensors: Robust Sensors for Cranes and Heavy Vehicles

Hardly any other application demands more from a sensor product than outdoor deployment. Operation and functionalities must not be affected by frequent and extreme temperature fluctuations, heavy impacts by shocks and vibrations, moisture, splash water or dust. Encoders, cable-pull encoders and inclination sensors installed at cranes or heavy vehicles in Construction, Agriculture and Forestry for position and angle feedback must withstand the most hostile environments.

Baumer provides an expansive product portfolio with sensor solutions that are specifically conceived for installation at cranes, mobile work machines and HeavyDuty utility vehicles: Absolute multiturn encoders that operate on a patented magnetic sensing principle master tasks like position feedback and rotational angle detection at crane booms. IP 67 protection ratings, excellent temperature resistance (from -40° to +120 °C) and optional redundant configurations ensure utmost operational safety and reliability. Communication with master control systems is via SSI or fieldbus interface, for example CANopen or SAE J1939. The same hallmarks apply to the robust and ultra-precise cable-pull assemblies that allow for both incremental and absolute encoder solutions and provide you with exactly the flexibility you need. Thanks to several cable measuring lengths up to 50 m and the high degree of linearity, typically 0.02% of the measuring range, they provide the requisite capabilities for dependable outrigger position feedback and position detection in drilling applications, at excavators and crane booms. Acquisition of vehicle tilt and boom angle is performed by robust inclination sensors with one or two channels and variable sensing ranges through a 360° angle that are available with numerous fieldbus interfaces.

But the robust Baumer sensors are capable of more. They not only endure the harsh conditions of outdoor applications but match even most demanding requirements in terms of safety and reliability by SIL and PL certified products and configurations that excel with an MTTF (Mean Time To Failure) rating of more than 100 years.
