P67 Series
Low Pressure Control
Description
P67 pressure controls are used to close or open an
electrical circuit, based on a predetermined air pressure signal. The
operating point of the control and the differential, are easy to adjust with the
externally-located adjustment screws on the top of the control enclosure.
The pressure controls incorporate a non-metallic diaphragm that is positioned by
air pressure changes. The diaphragm, in turn, actuates a heavy-duty
electrical contact clock using a lever mechanism.
Applications
Typical applications include the control of air compressors,
fans, pilot lights, resistance heating elements, and other devices.
Features
- long-life contact structure with high contact force
- easy-to-adjust settings: single sight set scales show both
cut-in and cut-out settings
