The pressure switch adopts high -precision, high -stabilization pressure sensor and transmitting circuit, and then through the special CPU modular signal processing technology to achieve the detection, display, alarm and control signal output of the medium pressure signal.The pressure switch can be widely used in the fields of petroleum, chemical, metallurgy, power, water supply and other fields of various gases, liquid surface pressure, and measurement control. It is an ideal intelligent test control instrument at the industrial site.
Pressure switch description
In the process of using the pressure switch, the selection of the set form is basically short -press form.For example, first, when the letter displays SET, we can choose to press for 2 seconds to display set.1 into the setting mode.Then by adjusting the UP and DOWN, the panel cycle display SAL, Sun, and set.You can choose to set up by pressing set.In the SAL settings, press the up and down keys, and the panel circulation displays Al, SALD, SALL, and SALH.Settings by short pressing the SET key. After the settings are completed, press the SET key to automatically enter the settings of the next option.
How to adjust the pressure switch
1. Pressure controllers with a setting value range of 0.1 ～ 1.0MPa (JC-20, HNS-210) 2. Move the pressure regulating screw on the right side of the top to make the pointer indicate 0.8MPa (8kg or 8bar of 8kg or 8bar at the benchmark ruler.At the same time, this value is the upper limit switching value.3. Move the pressure regulating screw on the left side of the top to make the pointer indicate 0.3MPa at the standard ruler, the lower limit switch value = upper limit switch value = 0.8-0.3 = 0.5, this value is the lower limit switch value.
The role of pressure switch
The pressure switch is mainly used on the air compressor to adjust the start and stop state of the air compressor. By adjusting the pressure in the gas storage tank, the air pressure machine is stopped and rests, and it has a maintenance effect on the machine.When debugging the air compressor factory, adjust to the specified pressure according to the needs of the customer, and then set a pressure difference.
Stress switch model
Pressure switch work principle
The working principle of the pressure switch is that if the pressure in the pressure switch is higher than or less than the safe pressure value of the initial settings, the discs in the sensor in the pressure switch can be sense and alert in time.Movement occurs, and connects with the guide rod to make the connector of the pressure switch connect the power or disconnect with the power supply.
