ENDRESS+HAUSER  FTI55-AAK1RG1W2A1A

Application

Solicap M is used for point level detection in bulk solids and can be operated in minimum or maximum fail-safe mode.

Due to its robust construction, it can also be used to provide accurate measurements in applications with very high tensile loads (up to 60 kN for rope version) or lateral loads (up to 300 Nm for rod version).

In combination with Fieldgate (for remote interrogation of measured values using internet technology), Solicap M represents an ideal solution for material provisioning and logistical optimization (inventory control).

Your benefits

• Extremely robust design for harsh process conditions
• Easy and fast commissioning as calibration is performed at the press of a button
• Universal application thanks to wide range of certificates and approvals
• Two-stage overvoltage protection against static discharges from the silo
• Active buildup compensation for bulk solids that tend to cake
• Use in safety systems with specific requirements in terms of functional safety to SIL2/SIL3 in conjunction with electronic insert FEI55
• Increased safety due to permanent automatic monitoring of electronics
• Reduction in storage costs thanks to easy-to-shorten rod model (for partial insulation) and rope model (for partial and full insulation)
• Two-point control (e.g. for controlling a handling device)

Measuring principle

The principle of capacitance point level detection is based on the change in capacitance of a capacitor as a result of the probe being covered by bulk solids. The probe and container wall (conductive material) form an electric capacitor. When the probe is in air (1), a certain low initial capacitance is measured. If the container is being filled, the capacitance of the capacitor increases as more of the probe is covered (2), (3).

The point level switch switches when the capacitance C S specified during calibration is reached. In addition, a probe with inactive length ensures that the effects of medium buildup or condensate near the process connection are avoided. A probe with active buildup compensation compensates for the effects of buildup on the probe in the area of the process connection.
