ELECTRNONIC PRESSURE SWITCH WITH SPDT RELAYS FOR AGGRESSIVE / VISCOUS / ABRASIVE MEDIA DESCRIPTION ASZ 3410 r is an electronic pressure switch with traditional SPDT relay outputs. Ceramic thick film sensor makes it a great choice for the aggressive(*) media. Flush ceramic diaphragm and the open port options are available for the viscous and/or abrasive media. 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 3410 r is a pressure switch and a transmitter at the same time, making this model stand out in comparision to conventional mechanical switches. SPECIFICATIONS Pressure ranges: 0.6 mbar up to 600 bar Setpoints, hysteresis: adjustable (*) Accuracy: ±0.5% Relay outputs: SPDT, 2 pcs Analog output: 4...20 mA (3-wire); Sensor: ceramic thick film Pressure port: G 3/4” (for flush diaphragm); G1/2”; G1/4”; 1/4” NPT; M20x1.5; etc Pressure port materials: stainless steel (for abrasive media), plastic (for aggressive media); Media temperatures: -20...+135 °C Ambient temperatures: -40...+70 °C APPLICATIONS Aggressive media(*) Viscous media Abrasive media Tank liquid level maintaining Sewage, waste water, sludge (*) please consult the manufacturer for particular media compatibility (**) set points and other parameters can be set either by factory or by user via PCON 200 adapter (sold separately) Appearance, mounting kit contents and/or specifications are subject to change without prior notice. We are constantly working on further improvement of our products. Delivery is subject to standard terms of delivery. © 2020 Piezus Page 1. Version: 11.0 Date: 20.05.2020
