QPL15.010 Siemens Pressure Switch

Overview

The Siemens QPL15.010 is a compact, adjustable gas pressure switch designed for the supervision of air or gas pressures in gas-fired equipment. This pressure switch is engineered to monitor whether a pressure falls below or exceeds a set switching point, triggering an electrical circuit to open or change over to ensure safe operation. It is commonly used in gas trains and is compatible with Siemens VGD series gas valves, making it a reliable component for commercial and industrial burner applications.

Features

• Adjustable switching point allows for precise pressure monitoring tailored to specific system requirements
• Compact design facilitates easy integration into existing gas trains and burner systems
• Automatic reset functionality ensures the system returns to normal operation once the pressure is within the set range
• O-ring connection type provides a secure and leak-resistant interface for mounting
• Built for durability with a designed lifetime of 50,000 burner startup cycles
• High protection rating of IP54 for resistance against dust and splashing water
