Description
For functional safety applications requiring a high degree of failure safety and availability. Used for safety-critical systems up to SIL3 in the chemicals, petrochemicals and oil & gas industries.
The Liquiphant FailSafe point level switch offers Safety Integrity Levels up to SIL3 with a single instrument requiring a high degree of failure safety and availability. The high SIL rating is achieved by dual redundancy and permanent self-monitoring of the instrument. In addition, a constant live signal monitors vital functions. Another benefit is the significantly simplified proof test according to IEC 61508/IEC 61511 functional safety requirements. Downstream devices in the safety loop such as valves are checked by simply pressing a button at the sensor or switching unit – saving both time and money.
Liquiphant FailSafe FTL80, FTL81 and FTL85 are available with a variety of coatings to cope with even highly corrosive media. Additional options provide a special design and materials to allow the sensor to resist process temperatures of up to 280°C. Liquiphant FailSafe can either be directly integrated into a (safety) PLC via a 4-20mA interface or can be installed with the Nivotester FailSafe FTL825.
