Advantages

• Non-contact and unaffected by head pressures

•High resistance • Self-cleaning effect of sensors • Integrated alarm/point level relay

• Universally useable due to •Flexible measuring range • Changing, highly viscous or •Remote access via Bluetooth® • Heartbeat Technology

aggressive media (100% PTFE)

Technical data • Connection •Accuracy • Process temperature • Process pressure • Process connection
