Pressure Switches
Dwyer pressure switches are designed to respond to changes in pressure, activating or deactivating a system or component when a specified pressure level is reached.
One of the key features of Dwyer pressure switches is their diverse application range. They are used in HVAC systems to ensure proper air flow, in process industries for controlling pumps and compressors, and in water management systems for monitoring water pressure. Their adaptability makes them suitable for environments where maintaining specific pressure levels is critical for safety, efficiency, and operational reliability.
Dwyer's pressure switches come in various types, including diaphragm-operated, piston-operated, and bellows-operated designs. Each type offers different sensitivity and pressure range capabilities, making them suitable for different applications. For instance, diaphragm-operated pressure switches are often used for low to medium pressure applications, while piston-operated switches are suitable for higher pressure ranges.
