Level switch in IP40 protection, which is designed for monitoring up to six levels in wells, reservoirs, tankers, water reservoirs and more. Up to 6 level probes (and one common one) can be connected to the switch. Each probe is monitored individually and can be set separately. Sensitivity can be set manually for L4, L5 and L6 probes. For all probes together it is possible to set a switching delay in the range of 0.5-10 s.

Probes not included in the package are required to measure the level. It is used to monitor the upper level, lower level and as a common probe.

Main features

• The measuring frequency of 10 Hz prevents polarization of the liquid and increased oxidation of the measuring probes.
• Output contact 9x switching 10 A.
• Power supply UNI 24 ... 240 V AC / DC (AC 50 - 60 Hz).
• Possibility to connect 6 probes (eg SHR-2).
