How to deal with pressure switch not jumping: electrical fault diagnosis and solution

The failure of the pressure switch to trip may be caused by mechanical faults, but electrical faults are also important reasons that cannot be ignored. In actual operation, electrical issues can interfere with the normal signal transmission and circuit control of pressure switches, making it impossible for pressure switches to operate normally even if they sense the set pressure. Next, we will delve into the diagnosis and solutions for electrical faults in pressure switches.

The power supply of the pressure switch is the basis for its normal operation. If there is a problem with the power supply, the pressure switch will not be able to obtain enough electrical energy to drive the internal circuit. Common power failures include power line open circuits, short circuits, unstable or abnormal power supply voltage, etc. For example, in some usage sites, due to long-term pulling and friction of the power cord, the insulation layer is damaged, resulting in internal wire breakage, and the pressure switch loses power, naturally unable to work normally. For power faults, we first need to use a multimeter to test the power line, measure the resistance values at both ends of the power line, and determine whether there is an open or short circuit in the line. If the resistance value is infinite, it indicates that the circuit is broken and the broken point needs to be found for repair or replacement of the damaged power cord; If the resistance value is close to zero, it indicates a short circuit in the circuit. It is necessary to carefully check the location of the short circuit and eliminate the fault. At the same time, it is necessary to measure whether the power supply voltage is within the rated working voltage range of the pressure switch. If the voltage is too high or too low, it may affect the normal operation of the pressure switch. At this time, it is necessary to adjust the power supply or replace the appropriate power supply equipment.

The wiring of pressure switches is also a link that is prone to electrical faults. Loose wiring, poor contact, or incorrect wiring can all cause poor signal transmission or circuit failure to conduct. During installation or maintenance, if the wiring terminals are not tightened, they may gradually loosen due to equipment vibration, resulting in poor circuit contact. In this case, although the pressure switch can sense pressure changes, the signal cannot be accurately transmitted to the control circuit, resulting in non tripping phenomenon. For wiring issues, we need to check each terminal of the pressure switch one by one to ensure that the wiring is firm and the contact is good. You can use tools such as screwdrivers to gently tighten the wiring terminals and check if the wiring is correct. Refer to the wiring diagram of the pressure switch to confirm that each wire is connected to the correct terminal. If wiring errors are found, they should be corrected in a timely manner to avoid damaging pressure switches or other electrical equipment due to wiring errors.

In addition, electronic components inside the pressure switch may also malfunction. For example, damage to components such as resistors, capacitors, transistors, etc. on a circuit board can affect the normal operation of the circuit. Resistance damage may cause abnormal current or voltage in the circuit, capacitor failure may cause poor signal filtering, and transistor failure may prevent the circuit from achieving normal amplification or switching functions. For the diagnosis of electronic component faults, it is necessary to have certain knowledge of electronic circuits and detection tools. We can use instruments such as multimeters and oscilloscopes to test the components on the circuit board and measure whether the parameters of the components are within the normal range. If a component is found to be damaged, a suitable replacement should be selected based on the model and parameters of the component. When replacing electronic components, attention should be paid to the welding process to ensure firm welding and avoid problems such as virtual soldering and short circuits.

In short, electrical faults are one of the important reasons why pressure switches do not trip. Through detailed diagnosis and repair of power supply, wiring, and internal electronic components, the problem of non tripping of pressure switches caused by electrical faults can be effectively solved. #Pressure switch; Not jumping; Electrical malfunction; diagnosis; solve
