EE56-VA25 Air Velocity Switch

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 (400...4000ft/min). It is based on the innovative E+E thin film sensor working on the hot film anemometer principle. This element is distinguished by its outstanding accuracy over the .

Features

compact case size interchangeable sensing probe easy setting of threshold and preset time remote sensing probe up to 10m (32.8ft) easy electric wiring easy installation Working Principle The sensing probe, which can be supplied with up to maximum 10m (32.8ft) cable, gives a signal to the relay module which is proportional to the air velocity. This value is compared to the threshold value set on the front panel of the air velocity switch. The relay is released if the threshold is reached or exceeded. To start without a hitch there are fixed and variable time steps integrated. When switching on.
