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 90
o
steps by software for better readability; HMI can be freely
swiveled 310
