DIGITAL GAUSS METER (Hand Held Type)
DIGITAL GAUSS METER MODEL S – 20 B
STR Model S – 20B is a low cost digital Hand Held instrument
for measurement of d. c. magnetic fields is using Hall Probes. It has
two ranges 20 K Gauss. A built in calibration facility ensures quick check
of calibration. All the controls are mounted on the front panel and are
clearly designed. An attractive plastic cabinet with carrying cum tilt
bracket takes make the instrument light in weight and portable. LED display
gives direct reading with 1 Gauss resolution on the 2k range and 10 Gauss
resolution on the 20 K range. The unit is supplied with a Calibrated transverse
Hall Probe of 50 mm x 1.5mm with the actual sensing area of 1 sq.mm from
the tip.
CIRCUITRY
The control unit consists of a constant generator, an amplifier and
seven segment LED display. A constant current is made to pass through
the Hall probe, which when place in a magnetic field produces a voltage
proportional to the magnetic filed. This voltage is amplifier circuit
and output is read on a digital panel meter calibrated in kilo gauss.
