SITRANS LG270 Guided Radar Level Transmitter
Brand: Siemens AGThe SITRANS LG series are guided wave radar transmitters for level, level/interface, and volume measurement of liquids and solids. It is unaffected by changes in process conditions, high temperatures and pressures, and steam. The SITRANS LG series comes in four different models, depending on the applications, level of performance, and functionality required.
SITRANS LG270 offers configuration options for extreme conditions including high temperature and high pressure applications such as: harsh applications found in chemical, HPI and energy industries for example, LPG gas tanks, steam boilers and distillation columns
Features- Extreme conditions with high or low pressures or temperatures
- Strong construction with dual seal to ensure its integrity in tough applications
- Real-time measurements for applications in steam boilers
- Measurement independent of gas readings
- Safety rated for 72 hours of unattended operation
- Second barrier for aggressive materials, including ammonia
