9.6. Temperature Sensor
The Mag-13 features an inbuilt temperature sensor that can be used to measure temperature
changes inside the sensor over time while taking measurements.
The temperature can be read from the same pin as the test coil as an analogue voltage output.
Measure the output between the relevant pin and signal ground. Refer to the product brochure for
the voltage output and temperature scaling parameters.
9.7. Connecting Power
Caution:
Check that the polarity of the supply is correct. Incorrect polarity can be prevented
by using the power supply and cables provided by Bartington Instruments.
Caution:
The power supply should be connected to the sensor before the supply is
energised, as this prevents high surge currents which could cause damage. Apply the
positive and negative supplies simultaneously and avoid leaving the sensor connected to one
polarity only.
9.8. Electromagnetic Compatibility
The Mag-13 range of sensors are electrically shielded from external, and emission of internal,
electromagnetic fields. Any emissions generated are at a low level with a primary frequency
corresponding to the frequency of the energising field of the sensor. The sensor is required to
respond to magnetic fields within the specified frequency band.
Caution:
Do not operate the sensor in very strong electromagnetic fields as it may develop a
permanent offset, or damage could occur to the sensing coils.
Note:
Do not place the sensor near to any equipment which may be affected by the very
small local field produced by the sensor excitation.
10. Performance
For detailed figures on the performance of the Mag-13 range of sensors, refer to the product
brochure.
10.1. Noise
The Mag-13 range includes different noise versions that are specified in the product brochure.
These versions correspond to the internal noise of the sensor, which can only be achieved in a
shielded environment where no external fields are present.
