Threaded Horn Antenna with extension
See table under
Threaded Horn dimensions
on page 13 for horn height to sensor
reference point (A, B, C, or D).
Notes:
• Process temperature and pressure capabilities are dependent upon information on
the process device tag. Reference drawing listed on the Tag is available on the
product page of our website at www.siemens.com/LR250, under More Info/
Installation drawings/Level Measurement/Installation Drawings/LR250. Additional
information on process connections is available on the Installation Drawings page
under Process Connection Diagrams.
• Signal amplitude increases with horn diameter, so use the largest practical size.
• Optional extensions can be installed below the threads.
