2PSD Differential Switch

• 

Product Summary

Solon Differential Pressure Switches are designed to sense a difference in pressure between two pressure sources. When the vacuum pressure from two dissimilar sources in a process is connected to a sensing diaphragm, the pressure difference creates a significant force. The force then moves a balancing mechanism to affect the minimal movement required for micro-switch actuation of the overall low differential pressure switch. 

What's Included

• Cast-aluminum housing available in explosion-proof or weather-tight options
• Frictionless switching mechanism, which amplifies the movement of the switching element, resulting in improved life, repeatability, and lower deadbands
• Available with one or two SPDT electric switches that are independently adjustable
• Removable enclosure cover for easy wiring and adjustment of the differential pressure setting
  • Features s/s screws that retain the cover gasket when the enclosure cover is removed
• Other useful options can easily be specified with this model including the "O" special feature for applications requiring higher working pressures

Reliability & Performance

Differential pressure switches are modular and configurable per customer requirement. In addition to the wide range of available features, Solon's Differential Pressure Switch models can be used in applications where pressure difference from a reference pressure must be indicated. Differential Pressure Switch models will sense a low differential on a very high static pressure. Applications that require level sensing, the pressure drop across a filter and two-way pressure differential are well-suited to the Differential Pressure Switch. 

Solon Pressure Switches are unique due to their frictionless switching mechanism, which amplifies the movement of the switching element, resulting in improved life, repeatability, and lower deadbands.

Unlike most "inline" pressure switch designs, the frictionless Solon mechanism amplifies the movement of the sensing element.
