Hazardous-area tanks need level control that matches 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.
PVC, PP and PVDF versions give the product family a practical material choice for plastic-based tank applications. The range supports up to 6 switch points and rod lengths up to 5 m, with maximum working pressure of 6 bar depending on the selected float. Standard working temperature reaches up to 100°C, with executions up to 130°C available on request.
Electrical integration can be adapted with 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 are available for PVDF, PP and PVC versions, with defined size, specific gravity, contact type, pressure rating and temperature class.
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.
Switch points L1 \div L6 are measured from the stop of the fitting or flange connection, with general tolerances of +/- 3 mm.
