Application Example: Juice Batch Tank With Sanitary Horn Antenna - Siemens SITRANS LR 300 Instruction Manual

Application Example: Juice Batch Tank with Sanitary
Horn Antenna
Notes:
• The minimum distance from the flange face to the target is limited by near-blanking
P800.
• Only set P837 if the product is at least 2m (78") away from the flange face. If it is
closer, leave P837 at 1 until the level drops and the distance increases beyond
2m (78").
• Choose First only (P820 = 12) if the SITRANS LR 300 is in the center. Otherwise,
keep it at 8 (bLF).
• Sanitary Antenna Options: The one-piece antenna/process seal provides an
excellent mounting method, even on non-sanitary installations.

SITRANS LR 300 – INSTRUCTION MANUAL
4" Sanitary Horn
This application is to obtain a level
measurement and corresponding
4-20 mA output proportional to the
juice level on a batch process tank.
The bottom of the horn is 5m from
the tank bottom. The empty level is
0m (bottom) and the full level (span)
is 4.5m from the bottom. The
maximum rate of filling or emptying
is about 0.5m/min.
In the event of a loss of echo, the
SITRANS LR 300 is to go into Fail-
Safe Hi after 2 minutes.
