ASZ 3420 r is an electronic pressure switch with traditional SPDT relay outputs. High quality silicon piezoresistive sensor and a microcontroller based electronic board provide a highly flexible and configurable solution for local equipment control. User is able to choose from a wide variety of relay triggering algorithms and adjust setpoints and hysteresis values (*). Additionally, an industry standard 4-20 mA analog output is provided, thus ASZ 3420 r is a pressure switch and a transmitter at the same time, making this model stand out in comparision to conventional mechanical switches.
(*) set points and other parameters can be set either by factory or by user via PCON 200 adapter (sold separately)
