The E+H Liquiphant FTL51B level switch is specialized for the process industry and already developed according to IEC 61508 to be used directly in SIL2 and SIL3 applications easily. You can conduct periodic proof tests according to SIL or WHG simply mobile with an intuitive app. At the end you receive an automated documentation. Liquiphant FTL51B measures reliably and is not affected by changing media properties, flow, turbulences, gas bubbles, foam, vibrations or build-up.

Heartbeat Technology module

Heartbeat Diagnostics continuously monitors and evaluates the device status and process conditions. Generates diagnostic messages when certain events occur and provides troubleshooting measures in accordance with NAMUR NE 107. Heartbeat Verification performs a verification of the current device status upon request and generates a Heartbeat Technology verification report showing the result of the verification. Heartbeat Monitoring continuously provides device and/or process data for an external system. Analysis of this data forms the basis for process optimization and predictive maintenance.
