4.3 Description
The TLS vibrating level switch is a general-purpose level switch. The core of the
vibrating level switch is the vibration drive integrated in the fork body, which drives the
fork body up to its resonance frequency. When the fork body is immersed in the medium,
the frequency of the fork body decreases and the frequency change is detected by the
electronic circuit and is converted to a switching signal. The model TLS-S vibrating level
switch is mainly used for overflow protection in vessels and pipelines, dry run protection
and pump operation protection. Due to its optional ATEX approval, the vibrating level
switch can also be used in hazardous environments.
