Note:
For sensors where the label area of the sensor is recessed, the label area should not
be used for clamping.
Caution:
The absolute maximum screw penetration depth within the body, as shown in the
relevant outline drawing, must not be exceeded.
Caution:
Do not place the sensor head of unpackaged or IE sensors in the immediate vicinity
of electrically conductive materials.
10. Operation
10.1. Connector Pin Allocation
The connector pin or cable colour allocation for the connection to each package type is shown on
the appropriate outline drawing available on the product page.
10.2. Interface
A simplified interface schematic for the Mag-03 series is shown in the product brochure. The
analogue outputs for the X, Y and Z axes are buffered to give a low output impedance, enabling the
unit to be operated over long cables and interfaced to high impedance data acquisition systems.
10.3. Power Supplies
The normal power supply of the sensors is shown in the product brochure. The ideal power supply
units are those manufactured by Bartington Instruments and listed at
www.bartington.com/data-
acquisition-and-conditioning-units.html
. Alternatively, users may wish to provide their own supply.
This would normally provide the minimum shown in the product brochure. For the lowest noise
applications, ripple in the power supply should not exceed a few mV.
Note:
Adequate performance of the sensor cannot be guaranteed if used with non-
Bartington Instruments products.
The nominal current requirements are shown in the product brochure together with an additional
current of 1.4mA per 100
m
T per axis that will be drawn in proportion to the measured field from
the positive or negative supply, depending on the direction of the field.
In the temperature range -40˚C to +70˚C, and with an external load of 10kΩ, the maximum
output voltage will be less than the supply voltage by the value shown in the product brochure.
All parameters, other than the output voltage range, remain unaffected for supply voltage (V
s
)
changes in the range from ±8 to ±15V.
