Capacitive Sensors
TURCK capacitive
proximity sensors can sense targets where a standard inductive
proximity or photoelectric won’t work. They feature non-contact
sensing of wood, glass, cardboard, plastics, concrete block, glue,
thin wires, silicon wafers, liquid levels through a sight glass
and other nonmetal material. TURCK embedded
sensors are suitable for flush mounting in steel. They also
feature solid-state output, high switching frequency and have no
moving parts. TURCK capacitive sensors are available in DC, AC and
intrinsically safe models.
TURCK’s
compensation electrode technology prevents false triggers. In
practice, sensors can be effected by water droplets, humidity,
dust, etc., causing false outputs. To combat this effect, each
TURCK capacitive sensor incorporates a compensating electrode
which forms part of a negative feedback circuit. When contaminants
are on the sensor face, they affect the sensor’s main field, as
well as its compensation field. The negative feedback circuit
detects the increase in both fields and can filter out the effect
of contaminants.

Flow
TURCK flow sensors monitor
reliably and wear free the flow of gaseous and liquid media.
The calorimetric operation of the sensors is based on the heat
transport / heat loss principle, i.e., when fluid moves over
the heated sensing probe, heat is conducted away from the
sensor. The heat loss is thus a measure of the flow speed.
There are immersion and inline sensors available which can
also be used in explosion hazardous areas.

Inclinometer
TURCK
inclinometer products utilize cutting edge technology to provide
level feedback in a compact, yet rugged package. Engineered
around a MEMS (micro-electromechanical system), these dual axis
sensors are designed to help keep your equipment within their
safe operating limits in the most challenging, rugged
environments.

Inductive
Turck
Inductive sensors serve for wear free and non contact
detection of metal objects. They operate with a high frequency
electromagnetic AC field which interacts with the target. With
conventional sensors, this field is generated by a LC
resonance circuit with a ferrite core coil. Uprox inductive
sensors operate on a new detection principle. In addition, due
to their ferrite less 3-coil construction, they incorporate
features which provide them with significant advantages for a
wide range of applications compared to conventional inductive
sensors.
