Introduction to the Gaussmeter

CAYLAR proposes a measurement of the magnetic field by Nuclear Magnetic Resonance (NMR) which allows to have an absolute measurement of the magnetic field without influence of temperature.

The Gaussmeter NMR20 is the successor of the famous Gaussmeter NMR 2 (Teslameter NMR DRUSCH). An approved technology since the 70's.

The new 2022 version of the NMR20 offers unmatched performance in all aspects. With the new FPGA-based frequency meter, the field reading is improved, more stable, more accurate with a hundred times higher resolution.
With the new embedded system, the NMR20 is faster, turns on instantly, more reliable and secure.


 
 
Specifications of the new NMR20 Teslameter Version 2022:
  •     <0.5 µT (<5mG) absolute accuracy.
  •     <0.01 ppm resolution in a uniform field.
  •     0.01 mG reading resolution.
  •     Up to 45 Hz reading frequency.
  •     High dynamic reading range (x5).
  •     High gradient tolerance: from 1000 to 2000ppm/cm (depending on the probe).
  •     Can measure very low fields 14mT (140G).
  •     Fast search of the NMR signal in less than 1 second.
  •     Display of the measurement on the front panel of the instrument.
  •     New very thin probes (<2mm) available.
  •     Probes adapted to radioactive environments without any active electronics.
  •     Analog output to regulate a current source.

NMR20 Gaussmeter Description

 
The CAYLAR NMR20 Gaussmeter uses the principle of nuclear magnetic resonance and can measure fields from 0.014 T to 13 Tesla with an absolute accuracy better than 0.5 µT without temperature drift.

The probe contains a small sample of resonant material. The sample has an absorption frequency proportional to the field. The measurement of this frequency allows to deduce the value of the magnetic field.
It is possible to connect the gaussmeter to an oscilloscope to visualize the resonance signal.

The NMR20 gaussmeter interfaces via Ethernet (TCP or MODBUS), USB and RS232 for remote control.
 
Different methods are available to search the NMR signal:
  •     manually with a potentiometer,
  •     automatically over the full range of the probe used,
  •     automatically by fast search around a reference value, in less than 1 second,
  •     automatically in less than 1 second by searching around the field value read by the embedded HALL sensor.

The Gaussmeter can be connected to a multiplexer, from which it is possible to choose from a number of probes to be controlled from the Gaussmeter.

To minimize the number of probes for a user, CAYLAR NMR probes have a dynamic range of 5. This means that for one probe, the maximum field strength measurement is approximately 5 times the minimum field strength.
Examples: 0.3 T to 1.5 T or 0.42 T to 2.1 T.
