(15) Description of product
The filling level sensors are used for continuous measurement of liquid levels within potentially explosive
areas. Floaters are used to detect the fluid levels. These slide on a sensor tube. For interface or water
detection, a second float can be mounted on the sensor tube. In addition, the density of the liquid can be
determined by means of a density module. The temperature measuring Chain VISY-Stick ... Temp ... is
used to measure temperatures at different heights and does not use any floats.
The filling level sensors type VISY-Stick ... and type TORRIX Ex ... may also be manufactured according to
the test documents listed in the ATEX test report. The changes affect the internal structure as well as the
change of temperature classes. Furthermore, the equipment was assessed according to the latest
Standards.
