Hazardous-area tanks need level control that fits both the medium and the protection concept. This intrinsically safe level switch is used to control 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, with float options defined by size, specific gravity, contact type, pressure rating and temperature class. The range provides up to 6 switch points and rod lengths up to 6 m. Maximum working pressure reaches 50 bar, depending on the selected float.
Electrical integration can be matched to the hazardous-area layout. Output options include IP65 housings, an IP66/67 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, S52 and S100 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 IP66/67 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.
witch points L1 \div L6 are measured from the stop of the fitting or flange connection, with general tolerances of +/- 3 mm.
