Air Logic switches interface from pressure signals to electrical systems. The snap-action electrical switch provides a positive and reliable response. The switch operation is based on the actuation of a precision snap-acting switch acting against a diaphragm.
The switches are single pole, double throw for normally open, normally closed and common terminals, which are available from 0.1 to 25 AMP, 15 AMP standard. For low current applications, gold contact switches are available.
Maximum pressure is 100 PSI. Adjustment ranges from 0.5 to 100 PSI. Special actuating and releasing pressures are available on request.
The switches include Miniature Switches, Subminiature Switches, Low Differential Switches and Solid State Switches.

LL SERIES REFRIGERANT FLOAT SWITCHES
This float controlled, magnetically actuated, mechanically operated, HERMETICALLY SEALED switch assembly can maintain close control of liquid level. The rugged construction makes it relatively insensitive to disturbances of the refrigeration system or vibration of the attached pipelines. The electrical switch, which is fused, and the operating mechanism are encapsulated within a transparent housing, which HERMETICALLY SEALS the moving parts and switch from ambient conditions and yet allows observation of the switching motion for determination of the liquid level. Type LLC, LLSC, LLAC are U.L. Listed for outdoor service. Types LLX, LLXS, or LLAX are not fused.

EE55 Series
Air Velocity Switch for HVAC Applications
The EE55 air velocity switch is designed for standard HVAC applications with a switching threshold between 2 and 20 m/s.
EE55 consists of an interchangeable sensing probe and a relay unit suitable for panel mounting. The electronics integrated in the sensing probe allow a cable length up to 10 m to the relays unit and ensure high immunity to electromagnetic perturbations.
Low angular dependence and an extension tube allows cost-effective, easy positioning of the sensing probe in ducts with diameter between 50 and 630 mm.
EE56 Series
Air Velocity Switch for lowest Velocities
EE56 air velocity switch is designed for special laminar flow and HVAC applications with a switching threshold between 0.2 and 2 m/s.
EE56 consists of an interchangeable sensing probe and a relay unit suitable for panel mounting. The electronics integrated in the sensing probe allow a cable length up to 10 m to the relays unit and ensure high immunity to electromagnetic perturbations.
Low angular dependence and an extension tube allows cost-effective, easy positioning of the sensing probe in ducts with diameter between 50 and 630 mm. For smooth plant start-up there is the possibility to set the delay time between 20 and 100 s.
