Liquiphant FTL51B - digital, simple and safe
- SKU:
- Liquiphant FTL51B Series
- Weight:
- 0.00 Grams
Description
Application
The Liquiphant FTL51B is designed specifically for the process industry and is optimized for direct use in SIL2 and SIL3 applications. You can easily perform periodic proof tests using SIL or WHG standards via a mobile device, guided by an intuitive wizard. Upon completion, the system generates automated documentation. The Liquiphant delivers reliable measurements, unaffected by changing media characteristics, flow rates, turbulence, gas bubbles, foam, vibration, or build-up. The device is user-friendly, features digital connectivity, and provides real-time data for immediate access.
This point-level switch is equipped with an extension tube suitable for all liquid applications.
- Process connections: Available in threaded, flanged, and hygienic options (Tri-Clamp).
- Temperature range: -50 to +150°C (-58 to +302°F).
- Pressure range: -1 to +100 bar (-14.5 to +1450 psi).
- Sensor material: 316L stainless steel, Alloy.
- Certified for international explosion protection, WHG overfill protection, SIL compliance, and marine approvals.
Benefits
- Universal limit detection based on proven vibronic technology.
- Developed in accordance with IEC 61508 for top-tier safety in SIL2/3 applications (certified by a third party).
- Periodic proof tests are simplified with guided wizards through the SmartBlue app or via an external test button or magnetic pin, ensuring quick and easy safety loop testing.
- Heartbeat Technology enables continuous diagnostics and easy verification without interrupting the process.
- Digital communication enables centralized asset management with seamless online access to all device information.
- Incorporates a second line of defense to protect the environment.
