Custom Differential Pressure Switches

Configure Custom Differential Pressure Switch

A low differential pressure switch is an electro-mechanical device that operates on the basic principles of levers and opposing forces. They are mainly used for detecting a difference in pressure between two points in a system. DP switches are a critical part of fluid monitoring processes because they help identify pressure differences that indicate flow loss.  In equipment such as boilers, this flow loss often results in equipment damage.
Differential pressure switches from Solon Manufacturing do more than monitor the flow of a process fluid. Our DP switches have a frictionless switching mechanism, which amplifies the movement of the switching element. The result is improved life, repeatability, and lower deadbands. Use our low differential pressure switches in any application where you need to monitor the pressure difference between two sources.

Differential Pressure Switch Elements

Low differential pressure switches contain three essential elements. These elements are used in various combinations to manufacture hundreds of deviations and include:
  • Sensing element made of either a bellows or diaphragm
  • Stable spring to determine the range set point
  • Snap-acting microswitch

Low Differential Pressure Switch Working Principle

Used for control purposes, a differential vacuum switch is 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.

Differential Pressure Switch Features & Benefits

Solon’s differential vacuum pressure switches provide numerous vacuum and pressure actuation benefits, some of which include:
  • Differential pressure monitoring and direct switching of electrical loads
  • For gaseous, liquid, aggressive, highly viscous or contaminated media, as well as aggressive ambient conditions
  • Process industry: chemical, petrochemical, on- and off-shore oil & gas, technical gases, environmental technology, machine building and general plant construction, water treatment, pharmaceuticals
  • Pump monitoring and control/filter monitoring, level measurement in closed tanks
Additionally, applications that require level sensing, pressure drops across a filter, and two-way pressure differentials are well-suited to Solon Differential Pressure Switch models.
