- Liquid Level Switch with Fail-Safe and Overfill Protection Functions
Product Specification Parameters
- Process Temperature: -60…+280 °C (-76…+540 °F)
- Process Pressure (Absolute Pressure) / Maximum Overpressure Limit: Vacuum…100 bar (1450 psi)
- Minimum Medium Density: Density not less than 0.4 g/cm³ (0.4 SGU)
Application Fields
The Liquiphant FTL80 tuning fork level switch can be used in explosive hazardous areas. It has obtained multiple international certifications and is equipped with fail-safe and overfill protection functions, with a functional safety level of SIL3. It ensures reliable measurement and is not affected by changes in medium properties, medium flow rate, disturbances, bubbles, foam, vibration, and adhesion.
The functional safety level of the level switch reaches SIL3.
- Process Connection: Threaded and flanged
- Temperature: -60 … +280°C (-76 … +540°F)
- Pressure: -1 … +100 bar (-14.5 … +1,450 psi)
- Sensor Material: 316L, Alloy C
Advantages
- Can be used in safety systems requiring SIL2/SIL3 functional safety levels, complying with safety standards including IEC 61508 Ed.2.0, IEC 61511-1, ISA 84-1, and DIN EN ISO 13849.
- Verification testing: The valid interval of verification testing is 12 years, and one-click testing of the entire loop equipment is supported.
- Permanent self-monitoring/internal redundancy.
- 4-20 mA interface (compliant with NAMUR NE 06/NE 43): Easy integration via dual-channel switch device (safety contacts) output and locking function (Nivotester FailSafe FTL825), or direct integration with safety PLC.
- No calibration required: Enables fast and cost-effective equipment commissioning.
- No mechanical moving parts, maintenance-free, wear-free, and long service life.
- Capable of monitoring whether the tuning fork has damage, corrosion, adhesion, or mechanical blockage.
