The use of oscillation sensors in various fields is also a lot, with the development of the market economy, the demand for sensors is increasing, but many people are not professional when purchasing, in order to prevent the purchase of undesirable products, how to choose when we choose the sensor? In fact, there are skills in purchasing products, for example, through some parameters to make decisions, parameters are an important goal for us to measure product quality, through parameters we can make a brief understanding of all aspects of the sensor. Whether it meets your own needs or not actually depends on the parameters to a large extent.
So what about those parameters in detail?
The first step is to look at the input quantity, how to see the input amount? Performance targets can be identified by the sensor's range or measurement scale, as well as overload capacity.
The second step is to look at the static characteristics, which are the input signals recorded when they are static, and the parameters that express the static characteristics mainly include linearity, hysteresis, repeatability, and stability.
The third step is to look at the dynamic characteristics, and after reading the static and look at the dynamics, what do the dynamic characteristics refer to? It is the characteristic of the output of the oscillation sensor when the input changes. The parameters that express the dynamic characteristics are mainly natural frequency, rise time, and steady-state error.
The fourth step is to look at the reliability goal, which aspects do you have to look at? Look at the technical parameters such as operating life, mean time between failures, and temperature and pressure resistance.
The fifth step is to look at the environmental requirements, which depends on the operating temperature scale, temperature drift and anti-media corrosion requirements.
The sixth step is to look at the use and mating requirements, which depends on important parameters such as power supply method and power consumption, as well as installation method.

The main classification of current sensors is ifm
(1) Resistance shunt: It is actually a resistance with a very small resistance value, when there is a current passage period, according to Ohm's law, the voltage occurs in the resistance, and the current size is known according to the measured voltage value. The resistance shunt has high precision, fast response, low cost, simple use, and disadvantages ...
