All inputs are protected against voltage surges. The unit incorporates a battery backed power supply for the sensors. Power is provided via a mains adapter and data transmitted to the user's computer via an optically isolated RS232 serial link. The analog signals from the sensors are available for external use. The data acquisition module can be located up to several hundred meters away from the sensors.
Software is provided for storing one minute average or five second values to disc.
This unit provides power for any Mag-03 sensor and signal conditioning of the sensor outputs. The power supply voltage can be increased for operation with the sensor over very long cables. All Mag-03 cables are supplied in 5 meter lengths, with alternative lengths to 600 meters available on request. It provides a reference magnetic field for testing the calibration of the cylindrical range of Mag-03 sensors. A temperature stabilized constant current is passed through a single Helmholtz coil with guides to align each of the sensor axes in turn.
