Autres informations sur les produits

T20X immersible magnetic probes are used for ascertaining the filling level limit values in tanks for liquid media. The materials used include PVC, PE, PPH, PTFE or stainless steel (1.4571), depending on requirements.

Through this the immersible magnetic probes are suitable for use with highly aggressive media. A ring magnet which switches the reed contacts built into the guide pipe is inserted into the float on the guide pipe. The switch contacts are hermetically sealed gas contacts which can be set up as changeover contacts or make or break contacts. With the E.L.B. limiting value magnet immersible probe it is possible to operate a number of switch contacts consecutively with one floater and, therefore, to measure a number of liquid levels. Monostable contacts are in-built as standard, i.e. the switch mode changes when the contact is operated by the magnet which is built into the floater. If the magnet goes above or below the contact, the contact will return to idle mode. If the contact is to be retained, an adjusting ring is required. If several levels are to be ascertained, several floats and adjusting rings are necessary. If required, bistable contacts are available, i.e. these contacts are operated and maintain this state until the contact is operated again. Please note! These contacts are shock-sensitive and therefore should not be used in the case of heavy turbulence.
