Description

Protection Plus with innovative corrosion protection
Capacitive RF probe with full coating protection

Longer service life due to increased corrosion resistance
UWT has further developed the RFnivo® 3100 capacitive level limit switch for this type of measurement task in the dust extraction of flue gases so that it meets and withstands the demanding conditions. All process-contacting parts of the sensor have been designed to be completely corrosion-resistant. Firstly, the RF boom is coated with PFA Teflon® and, secondly, a section of the process connection thread has been completely made of PTFE so that all parts in contact with the process are fully corrosion-protected.

Probe boom with PFA full coating
The shaft of the RFnivo® limit switch is fully coated with PFA Teflon®. It is resistant to almost all chemicals and can withstand high temperatures. In contrast to a spray coating, the type of coating of the RF probe is much more resilient, up to 1.5mm thick, and thus has more protection in abrasive applications.
The RFnivo® 3100 with fully coated probe boom can be made with a boom length from 200mm up to 1500mm and can therefore be used in a variety of installations.

Process connection thread made of PTFE
In order to ensure full and comprehensive protection of the process-contacting probe extension the process connection thread, which is connected to the boom, is made completely from PTFE Teflon®.
