Model Chart
Specifications
For on-off control of electrical devices such as air
compressors, fans, pilot lights, etc., by the use of a
predetermined air pressure signal.
Features:
• A variety of Pressure-to-Electric (P.E.) Switches permits
two-position electrical switching from either modulating or
two-position pneumatic signals.
• Models are available with either fixed or adjustable
differentials and with several different switch actions,
permitting selection of the best model for almost any
required application.
• May be wall-mounted or panel-mounted where necessary
