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 Process
Connection Specifications.
• Signal amplitude increases with horn diameter, so use the largest practical size.
• Optional extensions can be installed between the flange and the antenna.
