  • Page 2: Safety Notes

    Safety notes • The device should only applied by instructed personnel. • The power head emits strong magnetic radiation at 30-60 kHz to a distance of 300 mm. Therefore persons with cardiac pacemakers should not work with this device! • Magnetic data storage media should be kept in a distance of at least 3m from the power head to avoid data loss.

  • Page 3: Short Description

    Each 2-channel sensor module is equipped with signal conditioning, anti-aliasing filters, analog-to-digital converters (16 bit) and a digital communication bus connection. All these up to 128 modules (=256 channels) will be controlled by the MTP-NT-Controller module via a daisy-chain system bus (extendable to several meters). By this concept it’s possible to install the acquisition modules close to the sensor to have short connections for the analog sensor lines.
