The paper introduces the corrosion prevention of the automatic instruments for thermopair,resistance thermometer, transmitter, flowmeter levelmeter in Chemical processes.
Resonant absorption structure provides an effective method for designing and manufacturing microbridge resistor arrary with less power consumption and larger array.
High precision instruments of measuring electrical resistivity and magnetoresistivity are needed to study the inner structure and resistance characteristic of nanocrystalline materials.
The characteristic of variation of resistance for Polysilicon microresistor with time was measured under constant power operation using Digital Constant Power System(DCPS).
Insulance Ohmmeter, Model ZC25, can be used to measure insulation resistance of various electrical machinery, telecommunication element, household appliances and teaching electrical equipment.
Besides, there is also some alternatives, such as an inductance conversion using differential transformer and space curve deformeter, and variable resistance pressure transmitter.
Superfluidity is also closely related to other weird quantum effects, like superconductivity, where electricity can flow through wires with zero resistance.
