Pneumatic-Electric High/Low Alarm Switch
3-15# In - 2 SPDT Out
The switch is used to provide high and low signal alarm. Two independently adjustable SPDT switches provide 3 to 15 psig high and low alarm contact capability in this single device.
Each 10A switch adjustable between 1 and 27 psig
Pneumatic-Electric Pressure Switch
3-15# In - Electric Out
For on-off control of electrical devices such as air compressors, fans, pilot lights, etc., by the use of a predetermined air pressure signal.
Pressure ControllersPressure In - SPDT Floating Out
For the proportional pressure control of steam, air, gases, or liquids.
Pneumatic Flow Switch
The No. FS7-4A is a variation of the No. FS7-4 which substitutes an air valve for the electrical switch. Can be used to control pneumatic operated relays or valves when flow starts or stops. When flow drops below the necessary rate, the air valve opens, bleeding pressure from the control system.
P67 models are used to make or break 1 or 2 electrical circuits using a pneumatic signal. Typical uses include control of fans, compressors, and other electrical devices.
Pneumatic Differential Pressure Switch
Low Pressure In - Pneumatic Out
The PDP300 switch senses the flow of air in ducts or where differential pressure exists. Fan interlocking is very common. It includes a bracket for direct or surface mounting.
Air Flow Pressure Switch
Low Pressure In - SPDT Floating Out
These switches are used with reversible electric actuators to control differential pressures, low static pressures, or air velocities in duct systems.
Connection: 3/8'' O.D. Barb
Don’t Forget …
When installing these pressure switches, you’ll need sensing tubes, fittings and tubing.
These switches are designed to be compatible with any brand of pneumatic control system. Replaceable scale plates give you a variety of system functions. Standardizing on these switches will reduce your costs and help you become familiar with a single replacement for all uses.
