Robust sensors for heavy vehicles

March 2011 Sensors & Transducers

Baumer provides an expansive product portfolio with sensor solutions that are specifically conceived for installation for cranes, mobile work machines and heavy duty utility vehicles: Absolute multiturn encoders that operate on the magnetic sensing principle master tasks like position feedback and rotational angle detection at crane booms. IP67 protection ratings, excellent temperature resistance (-40 to 120°C) and optional redundant configurations ensure operational safety and reliability.

Communication with master control systems is via SSI or fieldbus interface, for example CANopen or SAE J1939. Precise cable-pull assemblies that allow for both incremental and absolute encoder solutions provide users flexibility. 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.

Durable for harsh outdoor applications, the sensors also match the requirements of safety and reliability by SIL and PL certified products and configurations that excel with an MTTF rating of more than 100 years.
