Motoron Semiconductors
Corporation, operating from the head office at Shakti Nagar in Delhi, is one of
the leading manufacturers of advance equipments and materials used in
experiments and research activities. They are developers of instruments like Digital Pressure Controller/Indicator, available in more than 100 different modes
and offer solutions to pressure measurement and control for any kind of liquid
in varied pressure range. Apart from this, Motoron Semiconductors Corporation
designs highly reliable and durable Nanovoltmeter,
which are also available in 8 different regular models offering
tailor made solutions to all industrial and research applications, meeting all
kinds of electrical, thermal, mechanical and environmental specifications.
MHECS series of experimental Hall Effect
Set Up are available in more than ten different models to explain
and understand the Hall effect in existing and new semiconductors, metals or
alloys.
Underlying Principle
Hall Effect Set Up by
Motoron semiconductors corporation works on the following principle: Vector
hall voltage generated on the basis of a force called Lorentz force, in any
metal, semiconductors or alloys is due to vector current flowing in the plane
of magnetic field. This Hall experiment is basically set up to observe the
following:
1. Normal Hall effect
2. Anomalous Hall effect
3. Charge carrier
4. Hall mobility
5. Electron and defect electron
These tabletop set up consists of
variable magnetic field electromagnet in various ranges from 5000 to 30000
gauss, precision electrometer with constant current source. These are suitable
for research and teaching institutes, generation, traction, telecom, airlines,
railways, electrical utilities, M.E.M.S, organic/inorganic chemicals, heavy
electrical/mechanical industries, sensors and many more related domains.
A Nanovoltmeter is the
foremost choice for online monitoring of low voltage signal and finds
application in generation, transmission/distribution, defense, and
electrical/mechanical m/c testing instrument, industrial electronics, railways
and avionics etc. These kind of precision instruments are compatible to any
standard or hall/shunt, thermocouple sensor and display with very high level of
accuracy; repeatability, reliability and they are available in various
materials like ceramic-coated MS, polycarbonate cabinets.
Digital Pressure Controller/Indicator finds applications in
areas like medical diagnostic, agro, biomedical, petrochemical, automobile,
organic/inorganic chemical, milk plant, sugar, textiles, beverages, water
management/treatment, academic and defense. The principle for working of these
indicators is as follows:
Fluids or gases passing via these
pressure gauges exerts pressure on diaphragm/bourdon as result inductance of
coil mounted on diafram/tube moves close to pick-up coil. This will lead to a
change in induce emf of pick-up coil. This is linearized to applied pressure in
accuracy range of 99 percent. It may have set point for alarm and may be
interface with PC using RS 232.
