Tank level control in hazardous areas needs clear switching and certified protection. This level switch is designed for liquids or fuel in underground and outdoor tanks where flammable products are treated. It is certified CESI 03 ATEX 272 Ext.2 II 1/2G Exdb IIB IIC T6/T5 Ga/Gb and provides a minimum ingress protection (IP) rating of IP67.
Inside the stainless steel rod, one or more floats actuate magnetic reed contacts. The float is the only moving element, supporting robust operation with limited maintenance. The product family offers up to 6 switch points, rod lengths up to 6 m and working pressure up to 10 bar, depending on the selected float.
Integration can be adapted to the tank connection and wiring concept. Threaded and flanged process connections are available, with aluminum epoxy-painted or AISI 316 stainless steel IP66/67 housings. Built-in temperature sensors can also be specified on request, including PT100, PT1000, PTC, NTC and TRP thermoprotector versions.
One or more floats actuate reed contacts placed inside the stainless steel measuring rod. Contact types include SPST and SPDT versions.
Spansil float options are available in several sizes, with defined specific gravity, contact type, pressure rating and temperature class.
External installation is supported with threaded and flanged connections. Thread options include UNI 228/1, UNI 7/1 and NPT.
Contact versions are specified with AC and DC voltage, current and power ratings for each SPST or SPDT contact type.
Contacts can be wired independently, with a common connection or according to request. NO, NC and SPDT contact status options are listed.
A sensor can be installed at the bottom of the rod on request. Options include PT100, PT1000, PTC, NTC and TRP thermoprotector versions.
