Description
ASZ 3420 p is an electronic pressure switch with PNP (high side) 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 p 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)
Applications
Industrial equipment protection
Pressure monitoring and control
Tank liquid level maintaining
Pumps, fans local control
