Description
Endress+Hauser FMI51: Reliable Level Monitoring Solution
The Endress+Hauser FMI51: Reliable Level Monitoring Solution is a robust, fully insulated rod probe engineered for continuous level monitoring in liquids. It is particularly adept at handling media that tend to build up and operates flawlessly even in extremely high-temperature process conditions. Its measurement principle is independent of the dielectric constant (dc) as long as the liquid’s conductivity is 100 μS/cm or higher, allowing for versatile use across various liquids without the need for recalibration.
Versatile Applications for Challenging Media
The versatile applications for challenging media highlight the FMI51’s exceptional capabilities. It’s an ideal choice for inventory management solutions when paired with the Fieldgate FXA320 for remote data acquisition. The FMI51 is a go-to for measuring various liquids, from those that form build-up to those in extreme process conditions, ensuring consistent and accurate level detection.
Capacitive Measurement Principle: Universal Use
The capacitive measurement principle: universal use ensures the FMI51’s broad applicability. This technology allows the probe to function reliably without recalibration across a wide range of liquids, provided their conductivity meets the specified threshold. This universality simplifies selection and implementation, making it a highly adaptable sensor for many industrial needs.
Engineered for Extreme Process Conditions
The engineered for extreme process conditions demonstrates the FMI51’s durability. It excels in applications with temperatures ranging from -80°C to +200°C (-112°F to +392°F) and pressures from vacuum up to 100 bar (1,450 psi). The use of corrosion-resistant materials, including PTFE, PFA, and 316L, ensures longevity and reliability even in the most demanding environments.
Safety and Compliance: SIL and Approvals
Safety and compliance: SIL and approvals are paramount with the FMI51. It is designed for use in safety systems requiring functional safety up to SIL 2, adhering to IEC 61508 standards. Furthermore, it boasts a comprehensive suite of international explosion protection certificates, WHG overfill prevention, hygienic certificates, and marine approvals, underscoring its suitability for critical and regulated applications.
