Calibration Cube / Reference Magnet
-
The SENIS Calibration Cube is an indispensable tool for the precise calibration of magnetic field sensors and mapping equipment. With a homogenous magnetic field accessible through six strategically placed holes in the cube's faces, users can easily place sensors from various sides to calibrate their sensitivity vectors accurately. This makes it an ideal solution for in-situ validation, ensuring reliability and accuracy in the user's environment. The calibration tool not only simplifies the calibration process with its intuitive software guidance, leading to the creation of a sensitivity matrix, but it also defines mechanical referencing with an orthogonality better than 0.1° across all three directions. In addition to its effective calibration capabilities, the SENIS Calibration Cube serves as a stable reference magnet, enhancing the user experience. The cube requires less than 30 minutes for full high-accuracy orthogonality recalibration, making it efficient for routine sensor changes on mappers. The included Calibration Cube Corner Tool further aids in ensuring accurate orientation to external Cartesian coordinate systems, solidifying its role in achieving the highest mechanical accuracy in magnetic sensor applications. Coupled with its dust-free surface for easy cleaning, the SENIS Calibration Cube stands as a reliable and high-performance calibration instrument.

Shunt Voltage References
-
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.
