Delta-Elektrogas PSG Pressure Switches

Reliable pressure monitoring is the backbone of any safe combustion process. The PSG series utilizes a sensitive diaphragm and a high-quality microswitch to detect even minute changes in line pressure. When the pressure reaches the user-defined threshold, the diaphragm triggers the switch, which can be configured for normally open (NO) or normally closed (NC) operation. This allows the switch to function as a high-pressure cutout, a low-pressure interlock, or a leakage detection component.

What makes the Delta-Elektrogas PSG Pressure Switches stand out is their mechanical durability and ease of calibration. Each unit features a clear, graduated adjustment dial, allowing technicians to set the switching point precisely without needing external gauges during initial setup. The housing is designed to withstand industrial environments, featuring high-grade plastics and metals that resist vibration and thermal stress. Furthermore, the PSG series is compatible with a wide range of non-aggressive gases, making it a versatile solution for safeguarding burners, regulators, and solenoid valves across various industrial thermal plants.
