Magnetic field characteristics of plane-single-tooth pole pair
Introduction
The magnetic field of a single-pole magnet is often likened to the one-eyed person in the proverbial room—you cant ignore its presence. Such a simple device presents complex behaviours that depend on the material, shape, size and orientation of the object. Magnetic field distributio......
Saturation Logging
What is Saturation Logging
Saturation logging, also known as resistivity and saturation log, is a type of geophysical logging method used to measure the amount of hydrocarbons present in a potential oil reservoir. The two main measurements taken using the method are the electrical resistivity and......
Thermal resistance
Thermistor
A thermistor is a type of resistor whose resistance varies with temperature. It is made from a metal oxide semiconductor material, usually manganese, nickel, or cobalt oxide, that exhibits a change in electrical resistance in response to a change in temperature. Thermistors are known ......
Dynamometer
Introduction
A power meter is an electronic instrument widely used for electrical power measurement. It plays an important role in electrical engineering, engineering research, and system monitoring and control. Not only does it measure real power, but can also be used to measure reactive, appare......

Operating Guidelines for Lattice Type Mixing Mill
1. Preparation before Starting
(1) Check whether the fasteners of the lattice type mixing mill are all firm, whether the safety protection devices are complete;
(2) Check the drive parts are located in the power-off state, and the dr......
Proportional solenoid technical parameters
Proportional Electromagnet Technology Parameters
Proportional electromagnets (also known as EMLs) are an important piece of technology for various applications in manufacturing, robotics, and other industries. They are also used in medical devices for dosimetry and positioning, as well as in aero......
Material requirements for thermocouples commonly used in electric furnaces
Introduction
Thermocouples are widely used in electric furnaces to monitor and control the temperature in a furnace. The thermocouple consists of two dissimilar metals (or low-temperature alloys) joined to form a closed circuit. When the free end of the circuit is exposed to a temperature, a smal......
Artificial graphite resistivity
