subject: Several Essential Guides to Choose an Industrial Sensor [print this page] Sensor is very beneficial for industrial since it is able to detect the condition of the machinery. With this device, the engineer is able to decide on when the machinery needs maintenance. However, before buying this device, there are some considerations which should be taken into consideration.
In brief, the consideration includes the level of the vibration, the frequency range needed and also the temperature range needed. In addition, it will be better for you to consider the presence of the corrosive chemicals, the combustible atmosphere, the presence of the electromagnetic fields and intense acoustic, and the size and weight of the sensor. However, there are some other important considerations you have to take.
In addition, there are some other considerations including the length of the cables, the temperature for the cables, the power supply required, and the instrumentation that will be used. Some sensors also need a splash-proof connector. Therefore, it will be better to determine in advanced whether you need a sensor with splash-proof connectors or not.
However, there are two main parameters you have to consider before buying the piezoelectric sensor, sensitivity and the range of the frequency. Generally, high frequency sensor has low sensitivity. In addition, most sensors with high sensitivity come with low frequency ranges. Therefore, it will be thoughtful to highly consider the frequency response and sensitivity before buying the sensor.
The Sensitivity Range
Typically, the sensitivity of the industrial sensor is in the range of 10 up to 100mV/g. However, there are also low and high sensitivity. Before choosing the correct sensitivity for the application, you have to know the range of the vibration amplitude levels since the sensor will be exposed to it during the measurements.
The Frequency Range
The most important thing to determine before choosing the frequency range for the sensor is the applications' frequency requirements. You can recognize the frequency requirements from the vibration data which is collected from the similar applications and systems. Instead, you can determine the frequency needed by placing a test sensor at some different locations on the machine and then evaluate the data which is collected.
