Vibronic
Point level switch for liquids
Application
• Point level switch for all liquids, for minimum or maximum detection in tanks,
vessels and piping, even in hazardous areas
• Process temperature range: –50 to +150 °C (–58 to +302 °F)
• Pressures up to 100 bar (1450 psi)
• Viscosities up to 10000 mPa⋅s
• Ideal substitute for float switches; reliable function is not affected by flow,
turbulence, air bubbles, foam, vibration, solids content or buildup
Advantages
• Approved for safety systems with functional safety requirements up to SIL2/SIL3
in accordance with IEC 61508
• Functional safety: monitoring of the vibration frequency of the tuning fork
• Heartbeat Technology via the free iOS/Android SmartBlue app
• With Bluetooth® wireless technology
