Product Identity

Rosemount 3300 Radar Level Transmitter.


Emerson Process Management, Rosemount Tank Radar has become aware of a potential problem involving certain MODEL 3300 RADAR LEVEL TRANSMITTERS. The affected model 3300 Radar Level Transmitters have been assembled without a zener barrier card but were ordered with a Hazardous Location Certificate which requires this card. Affected devices do not comply with the Hazardous Location Certificate e.g. it cannot be guaranteed that affected explosion-proof devices provide intrinsically safe outputs to the integral sensing probe. This means that the intended safety function is not there to protect against certain electrical failures. This can adversely affect the process application and cause property damage or personal injury.
