Explosion Proof Pressure Switch

Overview of Explosion Proof Pressure Switch

The Explosion Proof Pressure Switch is a safety-rated instrument that integrates pressure sensing, signal processing, and circuit control, primarily used for high/low limit monitoring and automatic control of medium pressure.

• What is it? The working principle of the Explosion Proof Pressure Switch is based on the elastic deformation of a sensing element (such as a diaphragm). When media pressure acts on the diaphragm, the resulting displacement actuates the internal microswitch. When the pressure reaches the set control value, the switch contacts quickly toggle, opening or closing the external circuit to achieve control and alarming.

• Main Application Field: It is primarily used in all industrial locations where flammable, explosive gases, vapors, and dusts are present. Typical fields include: petrochemicals, natural gas, refining, offshore platforms, pharmaceuticals, gas turbines, and hazardous goods storage.

• Key Characteristics: The main characteristics are its high safety rating and reliable electrical isolation. It boasts an Ex db II CT4-T6 Gb explosion protection rating and an enclosure protection rating of IP66, allowing it to work reliably in ambient temperatures ranging from -40°C to 60°C. Additionally, it features a high repeatability error of 0.5% or 1%, ensuring the precision of the control action.

Features of Explosion Proof Pressure Switch

Here is a summary of the main selling points of the Explosion Proof Pressure Switch:

1. Top-Tier Explosion-Proof Certification: Certified Ex db II CT4-T6 Gb, meeting stringent international and national safety standards for use in areas with flammable gases and dust mixtures.

2. High Enclosure Protection: The enclosure is rated IP66, fully protected against dust and water jets, making it suitable for wet, dusty, and severe outdoor environments.

3. High Repeatability: Features a low repeatability error of 0.5% or 1%, ensuring consistency and reliability of the pressure control point action, preventing false trips.

4. Wide Ambient Temperature Range: Rated for an ambient temperature range of -40°C to 60°C, suitable for extremely cold or hot industrial settings.

5. Reliable Microswitch Control: Utilizes high-quality microswitches for fast, snap-action switching, with a high contact capacity (e.g., AC  220V 6A resistive) capable of directly driving control systems.

6. Broad Media Compatibility: Suitable for various working media, including air, water, and oil, with low viscosity requirements and media temperatures up to 80°C.

Applications of Explosion Proof Pressure Switch

The Explosion Proof Pressure Switch is suited for safety-critical applications requiring strict pressure interlocks and automatic control:

• Petrochemical and Refineries: Monitoring high-risk fluid pressure in reactors, storage tanks, and pipelines to achieve emergency shutdown and interlock protection.

• Natural Gas Transmission and Storage: Controlling the start/stop of compressors and pumps to ensure gas pressure remains within safe limits.

• Gas Turbine and Boiler Systems: Serving as a critical pressure control point for flame supervision and safety protection.

• Hazardous Goods Storage: Monitoring the pressure high limit in tanks containing volatile chemicals to prevent explosion risks.
