Precision Shunts Using Copper-Manganese Alloy to Produce the Highest Precision up to ±0.1%

Precision Shunts Using Copper-Manganese Alloy to Produce the Highest Precision up to ±0.1%

Precision shunts are generally produced using copper-manganese alloy materials. Many precision shunts developed by resistor manufacturers on the market generally use copper-manganese alloy or constantan alloy. These two types of precision shunts are widely used and applied. The shunt can guarantee 0.1% sampling accuracy within the range of 10%-100% of rated current. The special structural design effectively reduces the thermoelectric potential error and connection error, and 100% calibration is achieved before leaving the fac...

Thin Film Resistor's Negative Etching Method and Lithography

Thin Film Resistor's Negative Etching Method and Lithography

Thin film resistor is a kind of more common resistor. Usually the manufacturing method of thin film resistor includes insulating substrate, forming a conductor pattern layer on the insulating substrate by non-photolithography. A thin film resistance layer is formed on the conductor pattern layer and the insulating substrate. The thin film resistive layer is patterned by photolithography. This thin film resistor manufacturing method can reduce the manufacturing cost of thin film resistor, but at present, many thin film resisto...

High-Power Resistor_the Relationship between Power and Volume

High-Power Resistor_the Relationship between Power and Volume

Power resistance is a common resistor. In many cases, the volume of power resistance is closely related to power, and the larger the power, the larger the volume. But not all power resistors are like this. Power resistors are made of different materials or processes, and can not be judged by volume. For example, the same volume of metal film resistance and carbon film resistance, the former is more than twice the power of the latter. In addition, the resistance value of the power resistance is not directly related to the powe...

DC shunts' Key Parameters and Matters Needing Attention in Use

DC shunts' Key Parameters and Matters Needing Attention in Use

DC shunt is suitable for measuring DC current, directly acting on analog display instrument below 10KA. DC shunt is a kind of external shunt which is suitable for measuring DC current and directly acting on analog display instrument below 10KA. In addition, DC shunt is used to expand the measuring range of DC current. It can also be seen as standard resistors for current sampling in sequential circuits. The sampling voltage of the DC shunt can be regarded as the analog signal of the primary current used in the measurement. In...

What is the Difference between Single Resistance Current Sampling Method and Three Phase Ones?

What is the Difference between Single Resistance Current Sampling Method and Three Phase Ones?

During the operation of synchronous brushless DC motor, it is usually necessary to sample the phase current of the three-phase coil of the motor to realize the closed-loop control of the motor. In the traditional three-phase current sampling method, three-resistance or double-resistance is often used to sample the motor current. However, the double-resistance and three-resistance sampling control circuit is complex and the manufacturing cost is high. Therefore, the method of using single resistance to sample the three-phase c...

What's the Advantage of Producing Manganese-Copper Resistor?

What's the Advantage of Producing Manganese-Copper Resistor?

High-precision Mn-Cu resistance alloy narrow ribbon is the core resistance material of various electrical instrument shunt elements. Manganese copper resistance can be used in all kinds of instrument relay, automobile relay, meter relay and so on. In the traditional process of resistance element, Mn-Cu flat strip resistance element is made up of large size Mn-Cu sheet (or strip) after punching forming and copper guide plate is made up of overlap welding. The resistance element of mn-Cu flat strip is composed of large-size Mn-...

What are the Advantages of a Continuous Resistance Testing Device?

What are the Advantages of a Continuous Resistance Testing Device?

In the existing technology, resistance testing instruments are widely used in laboratory testing or production line sampling. The connection end of the resistance tester connects the two terminals of the resistance. The resistance tester displays the resistance value. Manual single measurement can not achieve continuous measurement and mass resistance measurement. The efficiency is low. A continuous automatic resistance testing device fix the two ends of the resistance into a strip resistance belt, place it on the transmissio...

How does a Chip Resistance Testing Equipment Helps to Improve the Product Quality?

How does a Chip Resistance Testing Equipment Helps to Improve the Product Quality?

After all the process of chip resistance manufacture, packing will be carried out and placed on the carrying belt to form a strip. In the packaging, there will be some phenomena such as fragmentation, mixing, setting-up, inversion, placing, empty material, jumping material, material missing angle, carrying belt contamination, carrying belt damage, and so on. A bad resistance flowing to the client terminal and attached to the circuit board will result in the bad quality of the final product, and a security risk. Because of a b...
