Technical Characteristics and Performance Benefits
-
Active Build-up Compensation: The FTC260 features advanced electronics that automatically identify and compensate for material layers adhering to the sensor probe. This ensures that the switch only triggers when the actual bulk level reaches the probe, preventing false alarms in “sticky” powders like milk powder or gypsum.
-
Mechanical Safety and Long Life: Unlike traditional rotary paddle switches, the FTC260 has no moving parts. This non-mechanical design eliminates the risk of wear, jamming, or motor failure, ensuring a long operating life even in high-vibration applications or with abrasive materials.
-
Universal Material Compatibility: The sensor is optimized for light solids with a dielectric constant $\epsilon_r \geq 1.6$ and a maximum grain size of 30 mm. Its robust PPS (Polyphenylene sulfide) housing offers high resistance to aggressive media and mechanical impact.
-
Calibration-Free Commissioning: Designed for “plug-and-play” utility, the FTC260 requires no complex on-site calibration for the most common materials. This significantly reduces installation time and setup costs.
-
Integrated Protection: To guard against static discharges frequently generated during the rapid filling of dry solids silos, the device includes a multi-stage overvoltage protection system to safeguard the internal electronics.
