Application of pressure switch in the industrial field

Pressure Switch is a type of Sensors that outputs a switching signal, usually a relay or transistor switching signal. By setting the pressure alarm point, it plays a control function. For example, svlec YK47 series intelligent digital pressure switch can freely set the upper and lower limit alarm point, output the value of relay switch, and contact capacity AC220V/3A, DC24V/5A.

In industrial automation systems, pressure switches and pressure regulators are widely used control instruments to measure and control the gauge pressure and absolute pressure of various gases and liquids in petroleum, chemical engineering, metallurgy, power, water supply, etc.

Electronic pressure switches are used primarily for the protection and control of high and low pressure in commercial and automotive refrigeration systems, steam plants and power plants, accumulators, sump tanks, flash tanks, separators, scrubbers, and refineries. They can also be used to protect and control high and low pressure in various equipment and tools. Pressure switches, pressure monitors and electrical contact pressure gauges can monitor pressure changes. Once the set pressure range is exceeded, the switch is tripped to achieve automatic control and protection, making the production process safer and more efficient.

Use pressure switches to ensure safe and reliable equipment operation and achieve automatic control and protection.

When selecting electronic pressure switches, consider the following points:

A. The need for explosion protection: the explosion-proof forms are divided into explosion-proof and intrinsically safe types

B. Do you need guidance?

C. Number of contacts: 1 contact (1 output) or 2 contacts (2 outputs)

D. Set the setting value and pressure range: It is recommended to set the pressure range between 30% and 65%, and the setting range can be between 15% and 90% of the pressure range.

E. Different forms of connection and disconnection: adjustable or fixed

F. If there is pulsation: If there is pulsation or vibration in the pressure, a flow limiting valve needs to be used to prevent damage to the pulsation pressure gauge.

G. For single membrane case: When measuring corrosiveness, high viscosity or high temperature, the membrane type should be selected.

In an increasingly smart and automated industry, the use of electronic pressure switches and pressure regulators has become very complex.Svlec always adheres to independent research and development and innovation, masters independent intellectual property rights, and holds multiple patents in Bus Module, Sensor and Actuator, etc. Multiple series of products have passed authoritative certifications such as CE certification and CPA certification. Svlec always puts users first and provides cost-effective industrial electrical products.
