Sensors are things that we often use in our lives. There are many types of sensors, and many of them are unknown to us, such as pressure sensors. The pressure sensor has multiple functions of pressure detection, pressure display, alarm and control of pressure signal output. Today, let’s take a look at how the pressure sensor adjusts the pressure.
How does the pressure sensor adjust the pressure?
The pressure sensor has relatively high accuracy and stable performance, and is widely used in the petrochemical industry, metallurgical industry, power industry and water supply industry. It is an intelligent detection and control instrument.
The working principle of the pressure sensor is that if the pressure in the pressure sensor system is higher than or smaller than the initially set safe pressure value, the disc in the sensor in the pressure sensor can sense it in time and generate an alarm, and at the same time it will When the movement occurs, the joint of the pressure sensor is connected to the power supply or disconnected from the power supply by connecting with the guide rod.
When the pressure in the pressure sensor system returns to the initially set safe pressure value, the disc can sense it in time, and then return to its original position in an instant, and the sensor will automatically return to its original position and state. It should be noted that we need to understand the adjustment method of the pressure sensor.
- Select a pressure controller with a set value ranging from 0.1 to 1.0Mpa.
- Turn the pressure adjustment screw on the right side of the top to make the pointer point at 0.8Mpa (8kg or 8bar) of the scale, which is the upper limit switching value.
- Rotate the pressure adjustment screw on the left side of the top, so that the pointer indicates 0.3Mpa of the scale, the lower limit switching value = the upper limit switching value – the sensor pressure difference = 0.8-0.3 = 0.5, this value is the lower limit switching value.
