Advanced Equipments and their Working Principle

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.
