Description
The model FLM-H magnetostrictive sensor has been specifi-
cally designed for the requirements of the food and beverage,
pharmaceutical and biotechnology industries. The sensor
is particularly suitable for the special conditions of CIP/
SIP cleaning processes, such as chemical stability towards
cleaning liquids and high temperatures.
The guide tube is directly welded to the process connec-
tion, which guarantees a crevice-free connection, additional
sealings are not required.
The sensor is supplied with a DC voltage of 10 ... 30 V.
Available output signals are 4 ... 20 mA or 4 ... 20 mA with
HART ®  signal.
Level measurement
The hygienically designed sensor housing, with an ingress
protection of up to IP 68, offers a secure protection for
external cleaning with splash water and enables its use in
high-humidity environments.
The model FLM-H sensor fulfils the high demands of
sanitary applications. It is marked with the 3-A symbol and
current version number, as it conforms, based on a third
party verification, to the 3-A standard.
