What is a Pressure Switch?

A Key Component of Pressure Safety in Industrial Burner Systems

For safe operation in industrial gas and burner systems, not only the gas flow but also the pressure must be continuously monitored. A pressure switch is a critical safety device that measures the gas or air pressure in the system and protects it when the pressure goes outside predetermined limits. UK Teknik provides pressure switch supply, technical service, maintenance, and troubleshooting solutions for industrial furnace and burner systems.

What is a Pressure Switch?

A pressure switch is a safety switch that continuously monitors the gas or air pressure within a system and generates an electrical signal to shut down or alert the system when the pressure goes outside predetermined values.

Its main functions include:

• Controlling pressure
• Ensuring a safe operating range
• Shutting down the system at low/high pressure
• Protecting burner systems

How Does a Pressure Switch Work?

A pressure switch measures pressure using a diaphragm or mechanical sensing system and opens or closes contacts based on a predetermined threshold value.

Operating process:

1. System pressure is transmitted to the pressure switch
2. The internal mechanism senses the pressure
3. Contacts change when limits are exceeded
4. A signal is sent to the control system
5. The system enters safety mode or shuts down

This mechanism provides critical safety, especially in burner systems.

Pressure Switch Applications

Pressure switches are used in many industrial systems:

• Industrial furnaces
• Burner and combustion systems
• Premix burners
• Heat treatment facilities
• Gas lines
• Air supply systems

Safe operation is not possible in systems without pressure control.

Types of Pressure Switches

Various types of pressure switches are available for different applications.

Low Pressure Switches

• Detect gas or air drops

High Pressure Switches

• Break the circuit in case of overpressure

Adjustable Pressure Switches

• Limits can be adjusted according to usage needs

Differential Pressure Switches

• Measure the difference between two distinct pressures

Pressure Switch Failures and Symptoms

Problems can arise in pressure switches over time or due to environmental factors.

False Alarm

• System shuts down unnecessarily
• Production interruptions occur

Failure to Detect Pressure

• Safety system may become inoperable

Contact Fault

• Signal transmission is interrupted
• System goes into error mode

Calibration Drift

• Inaccurate pressure measurement occurs

---

Importance of Pressure Switch Maintenance

When regular maintenance is not performed:

• Safety risk increases
• False shutdowns occur
• System efficiency decreases

With regular maintenance:

• Pressure control remains stable
• Risk of failure decreases
• System safety is maintained

During maintenance processes:

• Pressure testing
• Calibration check
• Electrical connection check
• Diaphragm check

must be performed.

Considerations for Pressure Switch Selection

Correct product selection is critical for system safety.

Pressure Range

• Must be suitable for the system

Gas/Air Compatibility

• Must be selected according to the operating environment

Contact Type

• NO / NC configuration compatibility

Industrial Durability

• Must be suitable for high temperatures and vibration
