About the function, operation and use of the pressure switch Sensors

The Pressure Switch is a kind of pressure Sensors, and the output of the pressure switch is the switching signal. The function of the pressure switch is to detect, display, alarm and control the signal output to ensure the normal operation of the system. It collects and processes data through a high-speed MCU and compensates with a built-in precision Sensor. It detects pressure and liquid level signals and realizes monitoring and control of pressure and liquid level. high-precision equipment. It is widely used in automatic gas and liquid pressure measurement systems in chemical industry, engineering, hydrology, electricity, environmental protection and so on. As it is convenient and flexible to adjust and easy to install, it can replace the liquid level switch in most cases.

Precautions for pressure switch:

1. Determining the setting value and pressure range: the recommended setting range is between 30% and 65% of the pressure range, and the adjustable range is between 15% and 90% of the pressure range.

2. The shape of the port differs: adjustable or fixed.

3. Whether there is pulsation: When the pressure pulsates or vibrates, a throttle valve is required to prevent the damage to the device caused by the pulsating pressure.

4. Occasions with a diaphragm: When measuring corrosiveness, high viscosity or high temperature, it is necessary to use a diaphragm.

5. The need for explosion protection: explosion-proof devices are divided into flameproof and intrinsically safe devices, and most Nagano products are flameproof.

6. Need to bring instructions: according to the customer's instructions.

7. Number of contacts: one contact (one output) or two contacts (two outputs).

Knowledge of the use and maintenance of pressure switches

1. Before official use of the pressure switch with digital display, the user should check if all parts of the pressure switch with digital display are in good condition. Only if they are in good condition, they can be put into operation.

2. In order to set the digital readout pressure switch properly, each parameter must be set within the rated range of the digital readout pressure switch, and it must not be overloaded, otherwise the service life of the digital readout pressure switch will be affected.

3. During the measuring process of the pressure switch with digital display, it is best to have a special person in charge of monitoring to avoid emergencies during operation.

4. After each use of the pressure switch with digital display, the internal components must be cleaned to prevent the measurement medium from remaining inside.In order to protect the screen of the digital display pressure switch, in addition to regular wiping, it is best to wrap the screen with a clean bag to prevent dust and other pollutants from entering.

5. Regularly conduct performance tests on the digital display pressure switch to prevent the components from gradually aging due to cumulative use, which will have a certain impact on the measurement process.

The pressure switch adopts high-precision, high-stability pressure sensor and transmission circuit, and then adopts special modular CPU signal processing technology to realize the detection, display, alarm and control signal output of medium pressure signals. Pressure switches can be widely used in petroleum industry, chemical industry, metallurgy, power supply, water supply and other fields to measure and control the gauge pressure and absolute pressure of various gases and liquids.

It is an ideal intelligent measurement and control tool for industrial sites. Pressure switches are widely used in aerospace and military fields, such as M1A1 tanks, Apollo spacecraft, Boeing 747, Airbus A320, F22, F117 and other products.
