The NUS-7 ultrasonic level transmitter integrates both transducer and processing electronics into a single housing. It provides all the echo detection features of the established NUS-4 measurement systems, packaged into the two-wire NUS-7 sensor housing. Two-wire transmitters are recommended for applications powered by DC and for low switching capability. They excel in multiple tank applications using HART multi-drop systems linked to a modem plus PC. The NUS-7 comes standard with HART protocol and is suitable for most liquids under various process conditions. It comes with a scalable 4 to 20 mA output and programmable relay.
