Magnetometers - Import export

Electromagnetic system with a high field uniformity in the working volume ~ 1 cm3. It can be used for calibration of different types of magnetometers. Low power consumption allows continuous operation without cooling in the field range of ± 50 mT. The system can be controlled by a computer. Basic technical parameters: - overall dimensions - 280 × 340 × 340 mm; - net weight - ~ 95 kg; - maximal magnetic field induction - 50 mT; - the field inhomogeneity in the operating region - 0.01 - 0.05 %; - power consumption - ~ 200 W; - PC control mode, including the polarity reversal, is available.

The digital magnetometers of the DM Series are based on STL’s unrivalled high resolution ADC technology with 32 bit resolution and 26 bit dynamic range. The magnetometers use fluxgates as their magnetic sensitive elements and have integrated DXS. As a result of consequent digital signal processing, our magnetometers are quasi ideal sensors with digitally corrected geometry and temperature errors. The DM Series provides a measurement range of up to 1 mT, with an ultra precise digitization taking place immediately after the sensor output. All magnetometers measure the 3 orthogonal field components with a maximum sample rate of 10 kHz and offer very low intrinsic noise from 60 pT/√Hz @ 1 Hz down to 6 pT/√Hz @ 1 Hz. The software also offers the total field as an extra virtual channel. Typical error sources like axes misalignment, scaling, offset and phase errors are eliminated to the greatest possible extent due to its consequent digital signal conditioning strategy.

The MD200, manufactured by Trotech®, is a magnetometer suited for covered ferromagnetic metals locator such as valve caps and rods, hydrants, metallic manhole and tank covers, and the like. It is designed for environments like in the blazing heat, bitter cold, under water or in the snow to supply a location results that is accurate. It comes with a benefit of a covered ferromagnetic metal with a speedy detection and a reliability that prevents the detection of all non-magnetic metal objects due to its high sensitivity, and with an auto-manual adjustment that can function for 24 hours. Furthermore, a backlit display can be read easily along with a rotation function. It is designed to minimize discomfort and lightweight of only 830 g.

Induction magnetometer allows to measure magnetic field isotherms of magnetization (magnetization versus magnetic field (M(H) dependences) in the fields up to 2 T and in the temperature interval from 80 to 370 K. Magnetization is measured by induction method. Specification: - temperature interval — from 80 to 370 К, - magnetic field interval — from 0,02 to 2 Т, - relative measurement accuracy of magnetization - 2 %, - maximal sample dimensions - Ø1.5 × 3.7 mm. Magnetometer (its measuring part) consists of the measuring insert, electronic module and control and data acquisition program and can be used together with the magnetocaloric measuring setup (which includes permanent magnet adjustable magnetic field source, liquid nitrogen cryostat, temperature controller, 2 digital voltmeters, control computer with corresponding interface and control boards).
