CANHEADdirect simplifies measurement system cabling

The CANHEADdirect connects the measuring system to a PC for capture and analysis using a simple USB connection. Coverage of up to 250m for the complete system can be achieved by connecting the amplifiers with HBM's CANbus for data exchange and voltage supply.

CANHEADdirect simultaneously measures and records physical parameters such as strain, force and pressure. The system provides an inexpensive option for data acquisition in experimental structural and stress analysis undertaken by universities, laboratories and structural engineers. The system is suitable for static structural tests, fatigue tests, long-term monitoring, and measuring general structural mechanics such as wind energy plants and railway carriages, along with mechanical engineering components.

Cable influences such as temperature variations are compensated for by the regulated four-wire circuit for strain gages. Both internal and external resistances are available for shunt calibrations. All measurement data is completely synchronised and measurements can be implemented with single SG, SG full and half bridges, as well as with DC voltage sources.

HBM's catmanEasy software can be used to record the measurement data while self-programmers can read data with the help of the API documentation and transfer it to a separate system; an ActiveX interface is also available.

HBM also supplies the MGCplus, along with communication modules ML74 and AP74, for applications with more than five CANHEAD modules per measurement chain.
