Further product information
By using the conductive electrodes of our EE-21...F/EE-22...F line you can monitor conductive liquids within zone 0 (category 1). They are also approved by the “DIBt” (German Institute for Structural Engineering) as liquid level limit switches for the overfill protection of containers for storing water-endangering and combustible liquids. The screw connection of the EE-21...F/EE-22...F consists of stainless steel 1.4571. The electrode rods are made of stainless steel, 1.4571, Hastelloy B, Hastelloy C or tantalum. Through this the conductive electrodes EE-21...F/EE-22...F are suitable for use with highly aggressive media. The conductive electrodes of the EE-21...F/EE-22...F line are designed to be mounted within containers, the room inside the container can be classified as Ex-zone 0 (category 1).
- Overfill cut-out device Z-65.13-405
- EC Type-Examination Certificate TÜV 02 ATEX 1796 X
- Completely useable within Ex-zone 0 (category 1)
- also with unconnected cable end
- One electrode can measure up to 4 limit heights
- Optional assembling thread G 1" (for 1 limit height)
- Measuring the limit heights of conductive gassing media (ammoniacal gas liquor, fermentable solutions)
- Interference-proof measurement
- Interface measurement conductive / non-conductive
