Reliable level detection
in hazardous areas
LMT sensors reliably detect levels in storage tanks in explosive
areas. They can be used in zones 2 and 22. The sensor with its
high-quality housing materials such as high-grade stainless steel
(316L / 1.4404) and PEEK meets all requirements for hygienic
areas.This includes approvals such as EHEDG and FDA.
The LMT can be adjusted to almost all liquid and viscous media
as well as powders. The distinction between two media in the
same application is possible due to the two switching outputs
which can be set independently.
Convenient parameter setting is made via IO-Link. Applications
for these sensors include liquids, viscous media and powders.

High resolution level
measurement for sanitary
applications
WIKA’s model FLM-Hmagnetostrictive level sensor
has been specifically 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 clean-
ing processes, such as chemical stability towards
cleaning liquids and high temperatures.The guide
tube is directly welded to the process connection,
which guarantees a crevice-free connection, ad-
ditional 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. 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.
