Further product information
Fitting and tube of the EFV2 are made of PE, PPH, PVC or PVDF. The electrode rods are made of stainless steel 1.4571, Hastelloy B, Hastelloy C, titanium, tantalum or glass-carbon pins. This makes the overfill protection suitable for use with highly aggressive media.
The EFV2 overfill protection (24...230 V AC/DC) is adjustable, the response height can be adjusted on site (see dimensional drawing).
The ET-480a electronic unit installed in the junction box supplies a measuring voltage which causes an operating current to flow through the signal line via the resistor installed in the conductive electrode. If the conductive medium rises to the level of the electrode tips of the level sensor, a circuit is closed. This leads to a switching of the potential-free output contacts on the electronic part.
In order to cope with the different conductivities of the liquids, the sensitivity can be adjusted via the built-in potentiometer. If there is a line break, the output contacts are switched over (as with alarm by reaching the response level or voltage failure). If a line short-circuit occurs, this corresponds to an "alarm message" (as in the case of reaching the response level). The electronic part operates according to the closed-circuit current principle, i.e. in the event of a power failure, the output contacts switch as they do when the response height is reached.
- High chemical resistance
- Adjustable response height
- Line monitoring for cable short circuit / cable breakage
- Connection voltage 24...230 V AC/DC
System structure
The overfill protection can be connected to our "Optical Acoustic Alarm Devices" of the type series OAA-300.
