What is the resonant frequency of the sensor? Resonant frequency refers to the circuit containing capacitors and inductors, if the capacitors and inductors are connected in parallel, it may occur in a small period of time: the voltage of the capacitor gradually increases, while the current gradually decreases; The current of the inductor gradually increases, but the voltage of the inductor gradually decreases. And in another small period of time: the voltage of the capacitor gradually decreases, while the current gradually increases; The current of the inductor gradually decreases, but the voltage of the inductor gradually increases. The increase of voltage can reach a positive maximum value, the decrease of voltage can also reach a negative maximum value, the same direction of the current in this process will also occur positive and negative direction changes, called circuit electrical oscillation, when the resonant circuit external input voltage sinusoidal frequency to a specific frequency (that is, the circuit resonant frequency), the resonant circuit of the inductive reactance and capacitive reactance equal, Z = R, resonant circuit external pure resistance properties, that is, resonance. Now that the concept of resonant frequency is understood, let’s talk about its effect on the sensor. The high-frequency characteristics of the sensor depend on the first-order resonant frequency of the sensor’s mechanical structure, and the first-order resonant frequency of the sensor in actual use is often its installed resonant frequency. The mounting resonant frequency is determined by the natural frequency of the sensitive cell inside the sensor and the overall mass of the sensor and the mounting coupling stiffness. The level of the installed resonant frequency will directly affect the high-frequency measurement range of the sensor, so under the premise of having a stable resonant frequency of the sensitive core, improving the mounting coupling stiffness is an important condition to ensure high-frequency measurement. The sensor can be installed and output connector to reduce the effect of photoresonant frequency. The different installation forms of the sensor and the good installation quality will also directly affect the mounting coupling stiffness, which in turn changes the measurement high-frequency medium frequency of the sensor. The sensor’s signal output connector is also an important factor that can potentially influence high-frequency measurements. The lighter the weight of the sensor, the more significant the influence of connectors and cables on high-frequency measurements.
