Application area The flexible detector is used on round vessels and vessels with conical outlet and is suitable for measurement of liquids, solids, slurries and suspensions. Due to its thin, flexible scintillator cross-section, FIBERTRAC 31 can be easily adapted to round vessels. The FIBERTRAC 31 is a radiation-based sensor with flexible plastic sensing element for continuous measurement of liquids and bulk solids. It is suitable for level measurement under extreme process temperatures, in case of critical product features or aggressive products. The FIBERTRAC 31 delivers precise measuring results even under hardest application conditions. Your benefit Simple mounting on round and conical vessels through flexible detector High plant availability through non-contact measurement Cost saving through use of only one sensor up to 7 m measuring range Measuring range - Distance 7 m Process temperature - Process pressure - Accuracy ± 0.5 % Density Density Materials, wetted parts No wetted material Threaded connection Mounting from outside via supplied mounting brackets Seal material no media contact Housing material Aluminium Stainless steel (precision casting) Protection rating IP66/IP67 Output Profibus PA Foundation Fieldbus 4 … 20 mA/HART - four-wire Ambient temperature -20 ... 50 °C Explosion protection Intrinsic safety Ex ia Pressure-tight encapsulation Ex d Protection through housing St Ex Overfill protection WHG SIL qualification SIL2
