In what ways does the signal fail to manifest Allah? Why is the signal unstable? Generally, the output signal is unstable due to transient temperature changes that cause the bias voltage to fluctuate and fluctuate. How to deal with it? A sensor with a stable bias voltage is used for processing.
The noise of the measurement system affects the electrical noise of the sensor itself and the electrical noise caused by the cable will affect the measurement signal. In addition, there is also the power supply will also generate noise, so it is enough to choose a low-noise power supply, and finally there is a little range setting of the data acquisition system, and it is necessary to select the appropriate range.
External noise, the noise formed by the grounding loop, prevents multi-point grounding, and the sensor is insulated from the ground. When the sensor is affected by electromagnetic waves, it is best to choose a double-shielded sensor, and if it is affected by a strong sound field, a double-shielded sensor can be selected. Transient ambient temperature changes can also affect the signal, so a heat-insulated sheath can be used for high-sensitivity sensors for ultra-low frequency measurements; When affected by the strain of the base at the measured point, the user needs to choose a shear accelerometer with small strain on the base to minimize the contact area between the sensor and the measured object.

Advantages and disadvantages of capacitive sensors – Turck
Advantages of capacitive sensors
1. Good temperature stability
The capacitance value of capacitive sensors is generally independent of the electrode data, which is conducive to the selection of data with low temperature coefficient, and has little impact on stability due to its own small heat generation. The resistance sensor has copper loss, which is easy to heat up.

Choose the right laser displacement sensor method – Turck
1) Pay attention to the structure and data of the object to be measured, and the general laser displacement sensor needs to measure the triangular optical path with intact requirements. If the measured object has deep grooves or messy appearance, it may cause the triangular light path to be occluded, so that it cannot be measured. There are also some light-absorbing materials, such as black rubber and other materials, most of the light intensity will be ...
