The model PM40 is an easy-to-use pressure switch with a digital display and the possibility to adjust the sensor individually on site. The high overload capability compensates for pressure peaks in fast-closing systems such as drinking water applications with solenoid valves. Front-flush process connections reliably prevent clogging, even with viscous media. The large, brightly illuminated display can still be easily read from a great distance and therefore allows for a quick assessment of the process pressure. The upper part of the sensor can be rotated, in addition the display can be rotated via software for horizontal installation. The analog output with 2 adjustable switching outputs extends the range of applications. For our OEM customers, we offer the possibility of individual pre-setting of the PM40 for the respective application. Our modular design concept provides a wide variety of products. Feel free to contact us if you need a customization that is not listed in this datasheet.
