Installation
ULT20 transducers can be installed in any position. During installation it is recommended
to avoid mounting with the sensor facing up, as it can cause severe deposition of contami-
nants on the sensor membrane and lead to measurement errors. During installation the
sensor should be positioned in such a way that the
measuring head is perpendicular to
the surface
, to which the distance is to be measured. The view and dimensions of ULT20
transducer are shown in Fig .2.

Method of installation
ULT20 transducers are designed for installation in a hole with a diameter of 60 to 65 mm.
The maximum thickness of the material wherein the hole is formed is 20 mm.
On the outside of the sensor there is a M60x2 thread, which allows direct attachment of
the sensor to the mounting bracket or to the flange mounted in the tank. Take special
precautions to make sure that the sensor is not damaged during direct assembly in the
threaded hole. Never screw or turn off the transducer by twisting the aluminum housing
part .
Cable grommets located on the side of the housing are used for conductors connection.
While connecting conductors, special care should be taken that no cable touches the con-
