CE311 Key Features

Designed to withstand harsh environments
The CE311 444-311-000-031 sensor and protective tube are fully sealed and welded with 1.4441/1.4541 stainless steel to resist coolant, lubricant, and salt spray corrosion, with a 10-year failure rate of <0.5%.
Integrated electronics simplify deployment
With built-in charge-current conversion circuit, CE311 eliminates the need for an external charge amplifier, reducing system complexity and cost.
Intrinsically safe explosion-proof architecture
Certified by ATEX Zone 0, it is suitable for flammable and explosive scenarios such as natural gas compressors, which is superior to ordinary industrial sensors.
Long-distance low-loss transmission
The current output mode (50 µA/g) supports ≤1000 meters of signal transmission, and its anti-electromagnetic interference capability is 300% higher than that of the voltage output model.
