亚博提款要是刷流水吗materials used for sensors
亚博提款要是刷流水吗the use of material sensor materials is an important basis for sensor technology, with the progress of material science, people can produce a variety of new sensors. for example, polymer film is used to make temperature sensors, and optical fiber can be used to make pressure, flow, temperature, displacement and other sensors, and ceramic is used to make pressure sensors.
vibration sensor is a single free vibration system composed of springs, dampers and inertia mass blocks. using the inertia of the mass block to establish coordinates in the inertial space, the vibration acceleration of the relative earth or the inertial space is measured. through the transducer, the mechanical vibration is converted into electrical signal which is easy to transmit, transform, process and store.
eddy current displacement sensor
亚博提款要是刷流水吗the displacement sensor is actually a speed sensor because the electromagnetic induction electric law is applied in the principle of electromechanical transformation, and the electromotive force produced by the displacement sensor is proportional to the vibration speed measured.
亚博提款要是刷流水吗if the housing of the eddy current displacement sensor is connected with the zero line of the power supply and the zero line of the signal, we should pay attention to it. in order to prevent the disturbance caused by the different potential between the two places, it is suggested that the housing of the eddy current displacement sensor should be installed in the provided plastic card slot in the long distance measurement or on-line with the microcomputer to make the whole system single. point to ground, whether this situation will appear depends on the instrument used.
亚博提款要是刷流水吗application and unit of temperature transmitter
it is precisely because of the high accuracy of temperature transducer measurement, so it is widely used in various machines, such as general display instruments, and recording instruments, and even some large-scale electronic computers have used. there are absolute unit system and relative unit system: absolute unit system can objectively evaluate the size of vibration, relative unit system is expressed by "level", and level can be divided into two forms: arithmetic level and geometric level.
