Amplifier increases press-fit assembly accuracy

A measurement amplifier simplifies two-channel manufacturing and testing processes, such as press-fit monitoring, to ensure greater fitting accuracy.

The new MP85 measurement amplifier from HBM simplifies two-channel manufacturing and testing processes, such as press-fit monitoring, by checking two inter-related signals ensuring the optimum combination is obtained for greater fitting accuracy.

This is beneficial, for example, during the press fitting of bearings or sleeves, when the applied force can be checked against the displacement curve, to give clear guidance on the process quality.

Similar two-channel processes happen when monitoring clinching and fitting during assembly tasks.

The MP85 can also be used for monitoring rotational torque or angle curves in component and function testing, or for circularity tests where the rotational angle and displacement must be evaluated.

Almost any sensor can be connected to the MP85, such as strain gages, inductive or incremental transmitters, and SSI transducers.

The MP85 uses high-performance algorithms for curve evaluation with a maximum of nine predefined windows for each curve, or one master curve with envelope as evaluation criteria.

Users have the option of switching between absolute and relative reference co-ordinates to simplify parameter setting.

The MP85 uses digital I/Os to save statistics on component quality, either on a PC or an internal MMC card for later archiving.

The MP85 is available in a Profibus version, the MP85DP, ensuring optimum connectivity in the automation environment through CANopen and Profibus interfaces or digital I/Os.

To complement its amplifiers, HBM supplies a complete range of force, pressure and displacement transducers and torque flanges for comprehensive monitoring of production processes.
