| Description |
Series 8740 pressure switch adopts solid OLED display screen, which can display text very well. The display screen is slightly tilted, which is convenient for the operator to easily read the displayed pressure value from a long way off.
Series 8740 pressure switch adopts 3-key operation makes simple, intuitive menu navigation possible, with no need for additional assistance.
The installation of the series 8740 pressure switch can be flexibly adapted to the individual mounting situation. Due to the almost unlimited rotation of the display and case by more than 180°, the display can be adjusted independently of the electrical connection. The display can thus always be aligned to face the operator, and the M12×1 connection positioned to suit the desired cable routing. |
