Pressure and differential pressure measuring transducer / switch PREMASREG 7111-UW LCD

€257.83
Tax included

The electronic PREMASREG® 711x pressure sensors and switches are equipped with eight switchable measuring ranges, one switching output, one continuous output, and a display for setting the switchpoint and showing the actual pressure (eight devices in one, plus differential pressure switch / differential pressure monitor, continuous pressure sensor in a single device).

The sensor device has a housing made of impact resistant plastic, with cable gland or M12 connector according to DIN EN 61076-2-101 and with metal pressure port nozzles (quick connect optional). It is used to measure positive, negative or differential pressures in clean air, with limit value switching. The piezoresistive measuring element guarantees a high degree of reliability and accuracy.
