Zinc oxide pressure sensor is a polycrystalline semiconductor ceramic element made of a plurality of metal oxides, a classic electronic ceramic process, based on zinc oxide. Its microstructure is shown in Figure 1. Zinc oxide ceramics are composed of zinc
The pressure sensitive resistance MOV is mainly applied to low-voltage electrical surge protection, which is mostly zinc oxide pressure sensitive resistance. It is a polycrystalline semiconductor ceramic component made of zinc oxide as a body, doped with
1. The working ambient temperature of the pressure sensor should be within the scope of technical conditions. 2. The working voltage of the pressure sensor (continuously applied at both ends of the pressure sensor) cannot exceed the "maximum continuo
Dismissal from the different points of the two, as follows: First, the effect of the two is different: 1. The action of pressure sensitive capacitance: The capacitance used in the coupling circuit is referred to as a coupling capacitor, and such a capac
Varistor. Varistor (VSR) is the abbreviation of Voltage Sensitive Resistor, which is a new type of overvoltage protection element. The varistor is a metal-oxide-semiconductor ceramic component made of zinc oxide as the main material. The core material of
The pressure sensitive resistance is a resistor device with nonlinear voltammetry, mainly for voltage clamping, absorbs excess current to protect sensitive devices when the circuit is overlapped. The English name is "Voltage Dependent Resistor"
1, zinc oxide pressure sensor application principle The pressure sensitive resistor is used in parallel with the protected electrical equipment or components. When a lightning overvoltage or transient operation over voltage Vs occurs in the circuit, the p
When the voltage peak of the SSR exceeds the maximum voltage peak capable of exceeding the SSR, the component in the solid state relay can cause SSR damage, selecting a suitable voltage grade and parallel sensitive resistance. Protect the SSR. A. When the
Different use occasions, the purpose of the pressure sensitive resistance is applied, and the voltage / current stress in the pressure sensitive resistance is different, and thus the requirements of the pressure sensitive resistance are different, pay att
The pressure-sensitive resistance overheat protection technology has the following: (1) Hot melt fuse technology. The technique is to mount the low melting point metal with wax protection to the pressure sensitive resistance by a certain process, and when
