Burkert 8136 Mode D'emploi page 34

LEVEL TRANSMITTER 8136 • 4 ... 20 mA/HART - two-wire
– Slight sensitivity against sporadic false echoes
– Stable and reliable measured values through averaging
– High accuracy because not adjusted for max. speed
– False signal suppression recommended

•
Vessel:
– Installations in the bottom section (bracers, heating spirals)
– High sockets 200 ... 500 mm, also with large diameters
•
Process/measurement conditions:
– Condensation, buildup by movement
– Max. requirement on measurement accuracy from 95 %
•
Properties, sensor:
– Slight sensitivity against sporadic false echoes
– Stable and reliable measured values through averaging
– High accuracy
– False signal suppression required
