170190-01E  振动传感器  灵敏度较高，结构简单

170190-01E 振动传感器是一种将工程振动的参量转换成电信号的机电转换装置，有时也被称为换能器、拾振器等。它并不是直接将原始要测的机械量转变为电量，而是将原始要测的机械量作为振动传感器的输入量，由机械接收部分加以接收，形成另一个适合于变换的机械量，最后由机电变换部分再将变换为电量。因此，一个传感器的工作性能是由机械接收部分和机电变换部分的工作性能来决定的。

170190-01E 振动传感器主要监测旋转机械的振动情况，每种设备都有自己的振动标准，超过振动值，表明机器出现故障，所以振动传感器是起到对振动的保护作用。170190-01E在测试技术中，振动传感器是关键部件之一，它的作用主要是将机械量接收下来，并转换为与之成比例的电量。

常用的振动传感器有压电片谐振式等，170190-01E其中压电片谐振式传感器使用压电片接收振动信号，其优点是灵敏度较高，结构简单。振动传感器有多种分类方法，可以按机械接收原理分为相对式、惯性式等，也可以按机电变换原理分为电动式、压电式、电涡流式、电感式、电容式、电阻式、光电式等。

随着人们对自然认识的深化，会不断发现一些新的物理效应、化学效应、生物效应等，利用这些新的效应可开发出相应的新型传感器，从而提高传感器性能和拓展传感器的应用范围。同时，传感器的发展也日新月异，数字化、多功能与智能化是现代传感器发展的重要特征。

170190-01E Vibration sensor with high sensitivity and simple structure

170190-01E vibration sensor is a mechanical and electrical conversion device that converts the parameters of engineering vibration into electrical signals, sometimes known as transducers, vibration pickers, etc. It does not directly convert the original mechanical quantity to be measured into electricity, but the original mechanical quantity to be measured as the input quantity of the vibration sensor, which is received by the mechanical receiving part to form another mechanical quantity suitable for transformation, and finally converted into electricity by the electromechanical transforming part. Therefore, the working performance of a sensor is determined by the working performance of the mechanical receiving part and the electromechanical conversion part.

170190-01E vibration sensor mainly monitors the vibration of rotating machinery, each equipment has its own vibration standards, more than the vibration value, indicating that the machine is faulty, so the vibration sensor is to play a protective role against vibration. 170190-01E In the test technology, the vibration sensor is one of the key components, its role is mainly to receive the mechanical amount and convert it into a proportional amount of electricity.

The commonly used vibration sensors are piezoelectric plate resonance type, etc. 170190-01E piezoelectric plate resonance type sensor uses piezoelectric plate to receive vibration signals, which has the advantage of high sensitivity and simple structure. There are a variety of classification methods for vibration sensors, which can be divided into relative type and inertia type according to the mechanical receiving principle, and can also be divided into electric type, piezoelectric type, eddy current type, inductive type, capacitive type, resistance type, photoelectric type, etc., according to the electromechanical transformation principle.

With the deepening of people's understanding of nature, some new physical effects, chemical effects, biological effects will continue to be discovered, using these new effects can develop the corresponding new sensors, so as to improve the performance of the sensor and expand the application range of the sensor. At the same time, the development of sensors is also changing with each passing day, and digitalization, multi-function and intelligence are important features of the development of modern sensors.
