Further product information
The conductive probes EF2L and T with integrated electronics ET-473L and ET-473T are used to monitor double pipes and/or filling pipes.
The probes are approved by the DiBt for water-polluting liquids.
The conductive electrode EF2L, with integrated electronics part ET-473L, sets off an alarm in the event of leaks in double-walled pipelines. The conductive electrode EF2T, with integrated electronics part ET-473T, sets off an alarm if air instead of medium is present in the filling pipe. The use of these devices is preferred for water-polluting iquids that require DiBt test certification. The housing material consists of either PVC or PE.
The probe’s electrode tips are made of either stainless steel (1.4571), hastelloy B/C, titanium or tantalum
depending on the medium.
The electronics part is integrated directly into the probe tube. An optional NC or NO contact (closer or opener) is present at the connector port. Various installation and attachment parts can be supplied for the installation / attachment of the devices.
- Approved by DiBt according to WHG (Water Resources Act)
- High chemical resistance
- Electronics integrated in the probe
- NO or NC output
- Leakage / pipeline monitoring
- Filling pipe monitoring to
- protect against pressure surges
- Available as a complete unit with bonding sleeves, welding sleeves and ball valve
The double pipe and filling pipe moni-toring EF2L and T can be connected to our “optical and acoustic alarm” series OAA-300.
