Capacitance point level detection with active build-up compensation

Point level detection for fine-grained to coarse-grained bulk solids

Solicap FTI55 is a fully/partly insulated and robust rod probe for point level detection of fine-grained to coarse-grained bulk solids. It offers maximum reliability due to its active build-up compensation and is suited for a wide range of applications thanks to numerous certificates and approvals. Due to its robust construction, it can also be used to provide accurate measurements in applications with very high lateral loads up to 300Nm.

  • Benefits

    • Highest safety and reliability due to robust design for demanding process conditions
