Bartington Instruments designs, develops and manufactures high precision fluxgate magnetometers, magnetic susceptibility instrumentation, and related products for measuring, creating or cancelling magnetic fields.
Our range of three-axis sensors offer low-noise capability with a wide range of enclosures, configurations and packaging options. We have instruments of our own design that can operate at cryogenic temperatures, at temperatures in of 200ºC, in space and under the sea to depths of 5000m.
Our range of single axis fluxgates provide precision DC measurements of fields up to 2mT at temperatures as low as 4K.
Alongside these our range of data acquisition systems and conditioning units match specific needs for analogue conditioning, A/D conversion, magnetic field and vibration spectrum analysis, standalone signal conditioning and power supply.
Our three-axis Helmholtz Coil system has a maximum field of 500μT DC (100μT at 5kHz) and a 0.1% homogeneous field of 4.5cm3. Typical applications are experiments in which either a zero magnetic field environment or a specific magnetic field is required. Because the frequency and intensity of the field can be varied, the system can also be used for the calibration of three-axis magnetic field sensors.
The Bartington Instruments team also uses its 25 years of experience in customised product design to undertake projects for specific customer requirements. On request, we have designed electronics with noise levels down to a few pT at 1Hz for incorporation into instruments that combine high sensitivity with very low power requirements and drift (<10pTrms/√Hz @ 1Hz at 20mW). We have responded to customer demand by designing fluxgate probes for operation on drill heads, on aircraft, in space and at the bottom of the sea. Instruments can be designed to operate at cryogenic temperatures; in excess of 200ºC; in a vacuum; at pressures up to 500 bar; and to tolerate shocks to 600g and vibration to 6.8grms.
All Bartington Instruments sensors are provided with a Certificate of Calibration in accordance with our published specifications and the provisions of ISO10012-1.
We offer a range of training courses to ensure that users can best operate their equipment.
