Robust compact device for high demands
The level measurement system LB 490 Uni-Probe is a proven compact device provided with a robust stainless steel
housing. It comes at a reasonable price, is reliable and
precise and only requires very little source activity. It features all common communication capabilities such as
HART, Profibus PA and Foundation Fieldbus. A FMEDA
study revealed a SFF (Safe Failure Fraction) of 96 %. This
is an excellent result and an impressive testimony of the
high reliability and operational safety provided by these
systems.
