Hazardous-area tank control needs reliable switching with an intrinsically safe protection concept. This level switch is used for liquids or fuel in underground and outdoor tanks where flammable products are treated. It is certified CESI 03 ATEX 265 Ext.2 II 1G Exia IIC T4/T5/T6 Ga and II 1/2G Exia IIC T4/T5/T6 Ga/Gb.
The AISI 316 stainless steel construction supports demanding tank applications, while float options define the contact type, pressure rating and temperature class. The range provides up to 4 switch points and a maximum working pressure of 50 bar, depending on the selected float. Standard working temperature reaches up to 100°C, with executions up to 150°C available on request.
Electrical integration can be adapted with IP65 housings, an IP66 housing, DIN43650 plug, IP65 cable outputs and cable glands up to IP68. Exia level controls must be connected to active or passive barriers according to EN 50020.
Float options include S29, S32, S41 and S52 types, with defined size, specific gravity, contact type and pressure rating.
Internal and external installation are supported with threaded and flanged connections. Thread options include UNI 228/1, UNI 7/1 and NPT.
Output options include IP65 housings, an IP66 housing, DIN43650 plug, IP65 cable connections and IP68 or IP67 cable glands.
Contact versions include SPST and SPDT types with specified AC and DC voltage, current and power ratings.
Contacts can be wired independently, with a common connection or according to request. NO, NC and SPDT contact status options are listed.
Switch points L1 \div L4 are measured from the axis of the fitting or flange connection, with general tolerances of +/- 3 mm.
