How to connect the pressure switch
Pressure switches are a common industrial control component and are widely used in hydraulic systems, air compressors, water supply equipment and other fields. The correct wiring method directly affects the stability and safety of the equipment. This article will introduce the wiring method of pressure switches in detail, and attach recent hot topics as reference.
1. Pressure switch wiring steps
1.Preparation: Make sure the power is turned off and prepare screwdriver, multimeter and other tools.
2.Identify terminals: The pressure switch usually has three terminals: COM (common end), NO (normal opening end) and NC (normal closed end).
3.Wiring method:
| Terminal | Function | Wiring instructions |
|---|---|---|
| COM | Public end | Public lines connecting power or load |
| NO | Start often | Closed when the pressure reaches the set value |
| NC | Normally closed end | Closed when the pressure does not reach the set value |
4.test: After wiring is completed, use a multimeter to test the on-off status to ensure the wiring is correct.
2. References to recent hot topics
The following are hot topics on the Internet in the past 10 days for readers’ reference:
| Ranking | topic | Popularity index |
|---|---|---|
| 1 | New breakthrough in artificial intelligence | 98.5 |
| 2 | Global Climate Change Conference | 95.2 |
| 3 | New technology for electric vehicles | 93.7 |
| 4 | World Cup Qualifiers | 90.1 |
| 5 | Metauniverse development trends | 88.6 |
3. Precautions for wiring pressure switches
1.Power supply matching: Ensure that the power supply voltage is consistent with the rated voltage of the pressure switch.
2.Load capacity: The contact current of the pressure switch must meet the load requirements.
3.Protective measures: Protective covers are required for humid or dusty environments.
4.Regular inspections: It is recommended to check whether the wiring is loose once a month.
4. Frequently Asked Questions
Q: What should I do if the pressure switch does not work after wiring?
A: Check whether the power supply is turned on and use a multimeter to measure the on-off status of the contacts.
Q: How to distinguish between NO and NC terminals?
A: When the pressure is not applied, NC and COM are turned on, and NO and COM are turned off; the state reverses after pressure.
5. Summary
Correct wiring of pressure switches requires understanding of their working principle and terminal functions. This article provides detailed wiring steps and precautions, and attaches recent hot topics for reference. If you encounter any problems in actual operation, it is recommended to consult a professional.
Through the above content, I believe that readers can master the wiring method of pressure switches. If you need more technical information, you can follow relevant industry forums or consult equipment suppliers.
