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 block using a
lever mechanism.
Refer to the P67 Series Low Range Pressure
Control Product Bulletin (LIT-121445) for
important product application information.
Features
• long-life contact structure, high contact
force
• easy-to-adjust settings: single sight-set
scales show both cut-in and cut-out
settings
Applications
Typical applications include the control of air
compressors, fans, pilot lights, resistance
heating elements, and other devices.
