When the sensor is determined, the matching measurement method and measuring device can be determined. The success or failure of the measurement results depends to a large extent on whether the sensor selection is reasonable.
1. Determine the type of sensor based on the measurement object and the measurement environment
To carry out a specific measurement work, the first thing to consider is which sensor should be used. This requires analysis of various factors before it can be determined.
Because even if it is measuring the same physical quantity, there are many kinds of sensors available for selection. Which kind of sensor is more suitable, you need to consider the following specific problems according to the characteristics to be measured and the conditions of use of the sensor:
1） size of the range;
2 ）the position of the measured position on the sensor volume;
3） measurement method is contact or non-contact;
4 ）signal extraction method, wired or non-contact measurement;
5 ）the source of the sensor, domestic or imported, the price can withstand, or it is self-developed. After considering the above issues, you can determine which type of sensor to use and then consider the specific performance of the sensor.
