Deadband
Deadband is a region of pressure where a change in pressure produces no change in measurement output or control signal.
NO – Normally Open
Normally Open (NO) refers to the state of an electrical switch contact which stays open until a preset threshold has been met and the switch closes, e.g. a NO pressure switch set at 10 bar will close once the pressure exceeds 10 bar.
NC – Normally Closed
Normally Closed (NC) refers to the state of an electrical switch contact which stays closed until a preset threshold has been met and the switch opens, e.g. a NC pressure switch set at 10 bar will open once the pressure exceeds 10 bar.
Pressure Hysteresis
Pressure Hysteresis is the difference between two separate measurements taken at the same pressure but one where the pressure was increasing and the other where the pressure was decreasing. The hysteresis is caused by the natural reluctance of a pressure sensing material such as a diaphragm to return to its original position, shape or form […]
