These high temperature sensors have an amplifier completely
separate from the sensor. This allows the sensor to withstand
temperatures from –200 to +250°C (-382 to +482°F). The amplifier
is supplied in two different types, models S3624 & S3625, which is
suitable for one sensor, and models S3626 & S3627, which is suitable
for two sensors. The model S3624 & S3625 can be supplied
with delayed sensing. The sensors are available in 18mm and
30mm diameters, made of stainless steel and PTFE. Each sensor’s
operating distance is adjustable. This sensitivity regulation is useful
in applications such as detection of full containers and nondetection
of empty containers.
APPLICATIONS:
Typical applications include the level control of hot materials such
as liquids, oils, powder and plastic granules. These sensors can
also be used to sense solid metallic and non-metallic bodies positioned
in areas of high temperature.
OPERATING PRINCIPLE:
Capacitive proximity sensors use an oscillating field that can
sense conductive and non-conductive materials (metals, liquids,
glass, plastic, wood, paper and rubber). When an object enters
this field, an electronic circuit begins to oscillate. The rise or fall of
the oscillation is identified by a threshold circuit that drives an
amplifier for the operation of an external load. The operating distance
of the sensor depends on the target’s shape and size and is
strictly linked to the nature of the material.
