The Solicap FTI77 partially insulated rod/rope probe is used for limit detection of fine and coarse bulk solids. Thanks to its automatic buildup compensation, the probe offers maximum measurement reliability, has obtained various relevant approvals and permits, and has a wide range of applications. Its robust design allows high-accuracy measurement under extremely high lateral loads (maximum load of the rod sensor: 800 Nm), at high temperatures and in abrasive media.
Benefits
Extra-robust probe designed for demanding process conditions
Fast and simple calibration and commissioning via pushbuttons
Wide range of applications thanks to various approvals and permits.
Two-stage overvoltage protection against electrostatic discharge in the tank.
Automatic buildup compensation for bulk solids prone to caking
Can be used in SIL2/SIL3 safety systems in combination with the FEI55 electronic insert
Both rod and rope sensors can be shortened, reducing inventory costs
Application
This compact transmitter is suitable for limit detection of high-temperature bulk solids and can operate in minimum or maximum fail-safe mode. Its robust design allows high-accuracy measurement under extremely high lateral loads (maximum load of the rod sensor: 800 Nm) and in abrasive media. The integrated automatic buildup compensation ensures safe switching even where the medium is prone to buildup.
