Field of application
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.
For applications with very high lateral loads up to 300Nm. Fieldgate and Solicap represent a solution for material provisioning and logistical optimization (inventory control)
Process connections: Flanges and threads
Measurement range: 200 to 4,000mm (4 to 157")
Temperature: -50 to +180°C (-58 to +356°F)
Pressure: -1 to +25bar (-14.5 to +363psi)
International explosion protection certificates, SIL
Benefits
Highest safety and reliability due to robust design for demanding process conditions
Cost savings thanks to 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 build-up compensation for bulk solids with caking tendency (under development)
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)
