SENIS® Digital Gaussmeters/Teslameters and Analog Transducers with 1-, 2- or 3-axis integrated Hall and AMR sensors measure the magnetic field in the range of nT to 30T with an extraordinary magnetic resolution of 1ppm and an accuracy of less than 50ppm.
Magnetic Field Transducers:

analog magnetic field transducers
SENIS® magnetic field transducer consists of two modules:
⦁ Hall probe with the cable (H-Module)
⦁ Electronics for analog signal conditioning (E-Module)
To build up a complete measurement system, the E-Module needs to be connected to an adequate power supply and to a voltmeter (or A/D converter card). The performance of an Analog Transducer (e.g. resolution, accuracy, f-bandwidth, noise level, offset, etc.) is defined by the performance of the Hall probe and of the connected electronic module.
SENIS transducers are calibrated at SENIS’ ISO17025:2017 accredited calibration lab. SENIS provides different types of Transducers, which can fulfill most of requirements from industry and R&D laboratories:
⦁3-axis F3A and 1-axis F1A Transducers, with high spatial resolution Hall probes, high f-bandwidth and good accuracy and resolution
⦁I3C high resolution and low noise Transducers and moderate f-bandwidth
⦁MLNT-3D Digital Transducer, with very high resolution and low noise and with digital output
⦁3DACMT-1 Inductive Transducer, for high frequency and very high resolution
⦁H3A ultra high resolution and low noise Transducers
Digital Teslameter and Gaussmeter:

https://www.senis.swiss/mappers
SENIS® Magnetic Field Mappers measure magnetic field of permanent magnets and electromagnets by means of 3-axis Hall probes. SENIS Hall probes are calibrated at SENIS’ ISO17025:2017 accredited calibration lab.
Our innovative, smart probe connection technology allows an easy interchange of Hall and AMR probes, touch stylus and specialized probes, such as eddy-current probes for crack detection, sliding probes for in-contact measurements, probe arrays, etc.
SENIS’ mapper software provides real-time and off-line analysis and visualisation of measured magnetic field data, it generates a 3D map of the magnetic field, counts number of poles, calculates pole width for multipole magnets and rotors, detects zero crossings, measures magnetic angle, angle error and field homogeneity, provides GOOD/BAD decisions, calculates dipole magnetic moment, detects cracks in magnets and in non-magnetized blanks and much more.
SENIS offers several Mappers and Mapping Systems:
⦁ General-purpose, high-end standard-size mapper MMS-1A-RS:125mm^3 scan volume, 0.1% measurement accuracy, very high positioning accuracy, for all magnet types and forms
⦁ General-purpose, high-end large-size mapper MMS-1X-RS: same as MMS-1A-RS, but for larger magnets/rotors, i.e. 500mm^3 scan volume
⦁ Mapper for cylindric-shaped magnets MMS-2A-ROT: 155mmx55mm scan volume, 1% measurement accuracy, high positioning accuracy, for rotors, ring, disc and segment magnets
⦁ Entry-level portable mapper M3D-2A-PORT: 100mm^3 scan volume, 1% measurement accuracy, moderate positioning accuracy
⦁ Defectoscopes for crack detection in laboratories and as production EOL test equipment
