1. According to the input physical quantity, it can be divided into: displacement sensor, pressure sensor, speed sensor, temperature sensor and gas sensor.
2. According to the operating principle, it can be divided into: resistive type, inductive type, capacitive type and potential type.
3. According to the nature of the output signal, it can be divided into: analog sensor and digital sensor. That is, the analog sensor outputs an analog signal, and the digital sensor outputs a digital signal.
Fourth, according to the principle of energy conversion, it can be divided into: active sensor and passive sensor. Active sensors convert non-electric power into electrical energy, such as electromotive force, charge sensors, etc.; Passive program sensors do not have an energy conversion effect, but only convert the measured non-electric amount into electrical parameters, such as resistive, inductive, and capacitive radiant sensors.

Causes of bearing damage caused by ifm
Not all damaged bearings can be corrected, but the cause and extent of the damage to each damaged bearing must be evaluated to prevent or reduce further damage before considering the correction or replacement of a new bearing. There are many reasons for bearing damage, such as improper equipment, dirt invasion, etc.

The main feature of the wireless sensor network is the ifm sensor
(1) Large-scale
In order to obtain accurate information, many sensor nodes are usually arranged in the monitoring area, perhaps in the tens of thousands, or even more. The large-scale nature of the sensor network contains two implications: on the one hand, the sensor nodes are distributed in a large geographic area, such as in the original ...
