Position Sensor - R36AS Series0 pages

DESCRIPTION
RVDTs incorporate a proprietary noncontact
design that dramatically improves long term
reliability when compared to other traditional
rotary devices such as syncros, resolvers and
potentiometers. This unique design eliminates
assemblies that degrade over time, such as slip
rings, rotor windings, contact brushes and
wipers, without sacrificing accuracy.
High reliability and performance are achieved
through the use of a specially shaped rotor and
wound coil that together simulates the linear
displacement of a Linear Variable Differential
Transformer (LVDT). Rotational movement of
the rotor shaft results in a linear change in the
output signal, directly proportional to change
in shaft angle, over +/-60 degrees from the null
position. The phase of this output signal
indicates the direction of displacement from
the null point. Noncontact electromagnetic
coupling of the rotor provides infinite
resolution, thus enabling absolute
measurements to a fraction of a degree.
R30A/R36AS
The R30A and R36AS RVDTs are AC operated
rotary transducers. AC excitation of 3 V rms
results in a ratiometric AC output voltage That
varies in direct proportion to the change in
angular position of the transducer shaft. AC
operation eliminates the need for integrated
signal conditioning components thereby
offering the user an extremely wide operating
temperature range of -55°C to 150°C.
Factory calibrated to operate over a ±30
degree range, both the R30A and R36AS offer
a nonlinearity of less than ±0.5% of full scale.
Extended range operation up to a maximum of
±60° is possible with compromised linearity.
The R36AS is distinguished from the R30A in
that it incorporates a more rugged stainless
steel size 15 package, and MS style connector.
The R30A is packaged in a smaller size 11
aluminum housing with flying lead termination
for slightly less aggressive applications.
Both transducers offer superb performance and
long term reliability for applications such as
machine tool equipment, valve positioning, and
rotary actuator feedback.
