• Outstanding signal processing software
providing highly accurate measuring results
• PP or PVDF sensor body provides best
chemical resistance
• Secondary lightning protection
The type 2270 is a rugged, high performance ultrasonic
level measurement sensor, having transducer and
processing electronics incorporated in one single
housing. It provides all the sophisticated echo detection
features of the well accepted 2260 Ultrasonic Level
Transmitters.
For single and multiple tank applications 2-wire
sensors are recommended using either HART protocol
or 4 to 20 mA for the direct communication with a
panel mount controller or a PLC.
Either for liquid level measurement in sumps or tanks,
for tank contents measurement, or open channel flow
measurement, the 2270 Level Sensors provide the
answer. Sensing ranges up to 6 m are available. PP and
PVDF sensor bodies provide best chemical resistance
in applications where concentrated chemical shall be
detected.
• 4 to 20 mA / HART interface
Applications
• River water
• Seawater
• Potable water
• Demineralized water
• Treated water
