OMEGA offers many of its
liquid level switch products
with temperature sensing
capabilities. The incorporation
of thermocouples or RTD’s
can offer the user the ability to
determine level and temperature
in the vessel and save the cost
of having dual mounting
considerations. Linked with
OMEGA’s cable assemblies and
CNI Series Controllers, combination
sensors can provide a readout
of the environmental conditions,
as well as the capability to turn
associated equipment on and off.
