Density measurement with SENSseries LB 480


High-sensitive Detectors for Non-contact Process Measurements

The density detector SENSseries LB 480 is a compact field device combining cutting-edge measurement technology with the highest level of manufacturing quality and innovative features – the best system for high demand applications:

  •           density measurements
  •           concentration measurements
  •           solid content measurements

Safety Integrity

SENSseries LB 480 is the first radiometric density system on the market that has achieved SIL2 / SIL3 certification. Furthermore it provides many safety features and diagnosis functions such as a “Monitored Current Output” ensuring safe and reliable measurement during the complete time of operation. SIL 3 operation is possible in redundancy installations (1oo2).

Be SENSitive

SENSseries detectors have an outstanding sensitivity resulting in a significantly increased measuring accuracy. This allows for the use of very small source activities – a great advantage in terms of shielding costs and radiation protection matters.

SpeedStar

The product version SpeedStar is used when rapid process changes have to be detected immediately. It offers an unmatched quick measurement with update rates down to 50ms only. One example of application is the detection of slugs in the pipeline before they enter the production vessels further downstream.
