May 20, 2005 Model MP85 facilitates 2-channel monitoring by checking 2 inter-related signals. Almost any sensor can be connected to amplifier, including strain gage sensors, inductive or incremental transmitters, and SSI transducers. Model MP85 uses algorithms for curve evaluation with max of 9 predefined windows for each curve, or 1 master curve with envelope as evaluation criteria. Digital I/Os save statistics on component quality, either on PC or internal MMC card.
