It is one of the most commonly used fluid control components. We use digital pressure switches at home, in refrigerators, dishwashers and washing machines. Whenever we deal with gases or liquids, we almost always need to control the pressure. Our household appliances do not need high precision and high turnover. In contrast, pressure switches used in industrial machinery and systems must be rugged, reliable, accurate and have a high life cycle. Most of the time, we never consider the pressure switch. They just show up with machines or machine tools. In this kind of equipment, we rely on pressure switches to act as safety devices, alarms or control components in the system. But in most cases, we seldom consider this part when we buy it. How does the electronic pressure switch work?
Here is the content list:
l General knowledge of the use of the switch
l Indicator definition and working status description
1. Before the formal application of the switch, the user had better check whether all the parts of the digital pressure switch are in good condition and can be put into use only when it is in good condition.
2. If the switch is set correctly, each parameter should be set within the rated range of the digital pressure switch, and must not be overloaded, otherwise the service life of the digital pressure switch will be affected.
3. In the process of measuring the digital pressure switch, it is best to have a special person to observe, so as to avoid unexpected situations in the operation process.
4. After each use of the digital pressure switch, the internal components of the switch should be cleaned up to prevent the tested medium from remaining in it. In addition, in order to protect the screen of the digital pressure switch, besides wiping it regularly, it is best to wrap the screen in a clean bag to prevent impurities such as dust from invading.
5. The performance of the digital pressure switch is tested regularly to prevent the gradual aging of the components due to the cumulative application, which has a certain impact on the measurement process.
Power indicator | Always on when the power is turned on | |
Upper limit indicator | The upper limit is always on during the setting process, and in the running state, when the pressure is higher than the upper limit, the upper limit indicator is always on. | |
Lower limit indicator | The lower limit setting process takes a long time to light up; in the running state, when the pressure is lower than the lower limit, the lower limit indicator light is always on. | |
Unit indicator light | The default units are MPa, MPa, Kg/cm 2 and PSI, which can be switched arbitrarily. | |
Operation indicator | Flicker | The controller is in the running state and the relay is in the closed state. |
Bright | The controller is in the running state and the relay is in the disconnected state. | |
Not bright | The controller is in the set state and the relay is in the disconnected state. | |
Digital pressure switch is a new generation of pressure switch developed on the basis of the early traditional analog pointer barometer and high-precision digital sensing technology. It is used for the detection and control of air pressure in the field of pneumatic control. Guangdong NNT Pneumatic Technology Co., Ltd. also has these products, welcome to buy them.
