ATEX Version
This page refers to the orange DF555 ATEX version. The blue DF555 standard version is for non-hazardous applications.
IIC T6 Ga
Explosion Protection Marking
Marking: II 0 G Ex ia IIC T6 Ga, supporting intrinsically safe gas hazardous-area applications.
Ultrasonic Measurement
Measures liquid or solid surface level from the top without direct contact with the measured medium.
Wireless Monitoring
Uploads level data to cloud platforms for remote monitoring, alarm thresholds, and reporting.
ATEX Marking
II 0 G Ex ia IIC T6 Ga
The DF555 ATEX version is intended for projects where certified hazardous-area equipment is required. The marking indicates equipment group II, 0 G hazardous gas application marking, intrinsic safety protection ia, gas group IIC, temperature class T6, and equipment protection level Ga.
