Hazardous-area tanks need level switching that is simple to integrate and certified for the environment. This instrument is used to control 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 T5/T6 Ga/Gb and provides a minimum ingress protection (IP) rating of IP67.
The design combines a stainless steel rod with Brass and Spansil components. One or more floats actuate magnetic reed contacts inside the rod, with the float as the only moving element. This supports robust level switching with limited maintenance in tank applications.
The range provides up to 4 switch points and a maximum working pressure of 10 bar. Standard working temperature reaches up to 100°C, with executions up to 120°C available on request. Electrical outputs include IP66/67 housings in epoxy-painted aluminum or AISI 316 stainless steel.
One or more floats actuate reed contacts placed inside the stainless steel 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.
E1 and E3 output options use IP66/67 housings in epoxy-painted aluminum or AISI 316 stainless steel, with up to 18 terminals.
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.
