Vibration sensors are commonly used industrial sensors to detect and measure the vibrations of various mechanical equipment. To ensure the normal operation and measurement accuracy of vibration sensors, the following points should be noted:
1. Installation Location: The vibration sensor should be installed on the surface of the equipment whose vibration needs to be measured, and should be placed vertically or horizontally. Avoid installing it in locations that may affect the measurement, such as areas of strong vibration or areas where the temperature exceeds the sensor's tolerance range.
2. Cable routing: Cables should be routed according to the diagrams or instructions provided by the sensor manufacturer, and sensor cables should be kept away from high-voltage cables or other high-power sources in the same area.
3. Ambient temperature: The measurement range of vibration sensors is affected by ambient temperature. Attention should be paid to changes in the installation environment temperature and its impact on the measurement signal. At the same time, a suitable operating ambient temperature range should be selected according to the sensor specifications.
4. Vibration signal amplifier: In order to better measure vibration signals, a vibration signal amplifier is required. However, the installation and use of the amplifier must be carried out correctly according to the instruction manual.
5. Regular calibration: The measurement accuracy of vibration sensors will decrease over time. Regular calibration can ensure the accuracy and stability of the sensors.
The lifespan of a vibration sensor can be divided into two aspects.
First, there's the sampling period, also known as the data acquisition period, which indicates how often the sensor collects data. Vibration sensors typically have different sampling periods depending on the application requirements and data transmission needs. A shorter sampling period results in higher accuracy of the sensor's data acquisition, but it also increases the workload for data processing and transmission. Common vibration sensor sampling periods range from a few milliseconds to a few seconds.
Secondly, there's the duty cycle, also known as the operating time period, which represents the duration the sensor operates continuously within a given timeframe. The duty cycle is typically determined by the power supply and hardware design. If the sensor requires power-driven operation or periodic self-testing/calibration, the duty cycle may vary. Generally, the duty cycle of a vibration sensor is longer than the sampling period to ensure the sensor's stability and reliability during operation.
It is important to note that the lifespan of a vibration sensor can be adjusted and optimized based on specific application requirements and system design. Different application scenarios may require different sampling and duty cycles to achieve optimal performance and results.
