Why Hysteresis is a Valuable Feature For a Differential Pressure Switch

February 10, 2024

Hysteresis in a differential pressure switch is a valuable feature because it prevents the switch from constantly toggling on and off around the set point, which could occur due to minor fluctuations in pressure that are normal in most systems. Here’s a breakdown of what this means and why it’s beneficial. Constant Oscillation or Cycling […]
