Further product information
The EP plate electrodes are approved by the DIBt (German Institute for Structural Engineering) for monitoring collecting basins, collecting devices, control and filling shafts.
The detector body of the EP is made of the materials PE, PPH, PVC, PTFE or PVDF, depending on requirements. The electrode tips are made of stainless steel, 1.4571, Hastelloy B, Hastelloy C, titanium, tantalum or glasscarbon. Through this the EP is suitable for use with highly aggressive media. The electrode relays ER-107…, ER-217… or ER-145… (intrinsically safe control circuit) supply a measuring voltage which allows an operating current to flow via the resistance built in the conductive electrode through the signal line. If the conductive medium rises to the height of the electrode tip of the level sensor, a circuit is closed. This causes a change-over of the voltage-free output contacts on the electrode relay. In order to take into account different condu- ctivities of the liquids, the electrode relays ER-107…, ER-217… or ER-145… can be supplied in two different response ranges (1…30 k / 6…90 k). Within these ranges the responding value can be adjusted by means of a potentiometer. If a cable interruption occurs the output contacts are changed over (as for an alarm caused through reaching the‚ response height or a voltage breakdown). If a cable short-circuit occurs this corresponds to an “alarm signal” (as when the response height is reached). The electrode relay works according to the closed-circuit principle, i.e. in case of a power failure the output contacts switch as when reaching the response height.
