Accessories

PSU-1
The PSU-1 contains configurable high and low pass filters for the analog signals from the Mag-03, Mag649 and Mag690 sensors.
This unit supplies dc power to any Mag-13, Mag-03, Mag649 or Mag690 sensor using the ac adapter provided or from the internal rechargeable battery. The ±12 volt supply is fully isolated and the battery provides up to 10 hours of continuous operation.

SCU-1
The SCU-1 is a 19" rack mount unit that provides low noise power and precision signal conditioning for any Mag-13, Mag-03, Mag649 or Mag690 sensor. The unit operates from a 110 or 220 Vac mains supply.

Magmeter
The Magmeter 2 is a portable, battery powered unit provides both power for magnetic field sensors and simple access to filtered versions of the sensor's XYZ outputs. It incorporates three displays showing the values of the magnetic field being measured by the connected sensor. Low-pass filtering (9kHz) is applied to all sensor outputs. A high-pass filter (0.1Hz) is also selectable via a front panel switch.

Mag-03DAM
The Mag-03DAM is a 6 channel, 24 bit resolution analog to RS-232 digital data acquisition module for the collection of data from any two Mag-03 sensors. If used in conjunction with one sensor only, the three remaining inputs may be used to record analog signals from other sources.
Power is provided from an ac adapter. Data is transmitted to the user's computer via an optically isolated RS-232 serial interface. The unit incorporates a battery backed power supply for the sensors.

Mag-Shield, 100mm
The Mag-Shield is a triple-layer, mu-metal, magnetic shield cylinder with open ends for easy access. Available internal diameters are 100mm, 120mm and 140mm with length of 300mm. The 100mm ID is normally stocked.

Degaussing Wand
The Degaussing Wand is a mains powered, handheld instrument that is used for removing accumulated magnetic fields from other devices. Instruments that measure magnetic fields can become magnetized themselves, thus adversely affecting their performance.
