Electronic pressure switch Smart DCM DIFF

differentialM12 connectorthreaded

Electronic Differential Pressure Switches are microprocessor-controlled pressure measurement devices for a differential pressure range of 0 ... 20 bar. They are suitable for an extremely wide range of applications, including the precision recording, monitoring and control of system pressure. They come complete with an angled M12X1 plug and are mounted directly to the pipe via two G1/4" internal thread connections. Features: • - Open-collector • - Configurable as min./max./window monitor • - LCD graphical display (Human-Machine-Interface models, only) can be swiveled for better readability; display can be rotated in 90o steps by software for better readability; HMI can be freely swiveled 310o • - Self-monitoring electronics • - Adjustable drop-in/drop-out delay Sensing element material - Stainless Steel Kind of pressure - differential pressure, relative Power supply - 24 Vdc | 1 VA Medium type - liquid or gas IP class - IP65 Climate class Indoors 4K4H as per EN 60721-3-4 Outdoors 3K8H as per EN 60721-3-3 Mechanical stability Vibration 10 g as per IEC 68-2-6 (up to 2000 Hz) Mechanical shock 50 g as per IEC 68-2-27 Pressure resistance see Table 1.
