Dispalcement measurement for mobile hydraulics

11 July 2007 Test & Measurement

With its Micropulse AR, Balluff now offers an absolute, non-contacting displacement measuring system for use in mobile hydraulics. With its compact design, the sensor can be integrated directly into the cylinder where it is protected from wear, contamination or moisture. The processing electronics, which are embedded in the sensor head, have been designed to meet the strict EMC Directives for industrial trucks, agriculture and forestry as well as earthmoving equipment.

The Micropulse AR makes possible continuous feedback of the cylinder position and thereby offers constant monitoring of the work processes, high performance and increased safety and reliability. It operates reliably in areas characterised by strong electromagnetic fields, such as found outdoors beneath power lines. Equal reliability is found in agricultural equipment, which remains unused for long periods of time due to seasonal use. This linear displacement system will operate on machines having longer downtimes, such as mowing machines, which may lay idle for months at a time.

Customers can select various output signal types depending on their needs in terms of vehicle power.

The Micropulse AR works within an operating range of 10 to 30 V, which means it can be used where sometimes two devices have to be employed, one for 12 V and one for 24 V. It is available in the standard version with a 10 mm rod diameter or with an 8 mm rod for smaller cylinders. It is also available with all the accessories such as magnet rings and mounting elements from the Balluff line.

Typical areas of application for the Micropulse AR include agriculture, in levelling machinery, or in construction machinery for automating continuous movements and work sequences.
