Universal digital teslameter 43205
Designed to measure:
- radial component of constant magnetic field induction (0-1500mT, ± 0.5%)
- radial component of sinusoidal RMS form of alternating magnetic field (0-100mT, ± 4%);
- axial component of constant field induction (0-19.99 mT, ± 2.5%)).
Universal Teslameter 43205 (hereinafter the device) is used for measurements: radial component of sinusoidal RMS form of alternating magnetic field with the help ofprimary converter thickness do not exceed 0.95 mm; axial component of constant field induction with the help of 6 mm diameter primary converter.
Connecting primary transducers with input devicesconnector of Teslameter 43205 is carried out with flexible cables length 1.5 m.
Selecting measurement range and type of measured induction - manual. Polarity of static magnetic field induction determination, and its indication by device Teslameter 43205 - automatic.
Climatic factors values in accordance with GOST 22261-82, group 2 and GOST 15150-69, conditions YXL 4.2. DC and AC magnetic fields radial component induction measured by primary measuring converter PIP-PAD, made in the probe form. Axial induction component of static magnetic field is measured by primary measuring transducer PIP-AKC, made in the probe form.
Warning! Mechanical force application to measuring parts of primary transducers is unacceptable!
