Gauge Pressure (Vacuum) Switch
A switch that compares the pressure being sensed to that of atmospheric pressure. Positive pressure switches sense monitored pressure above atmospheric pressure while vacuum switches sense pressure below atmospheric. |
Temperature Switch
A Neo-Dyn temperature switch is identical to a pressure switch with the addition of a fluid-vapor charged sensing probe. The fluid-vapor charge is exposed to the "basic sensor" and since probe pressure varies with temperature, discrete temperature settings can be accomplished. |
