transducers. The RVIT proprietary design

incorporates a set of four printed circuit coils and

a light-weight aluminum spoiler to achieve

superior response while maintaining a low

moment of inertia. During operation, the light

weight spoiler rotates with the transducer shaft,

differentially altering the inductance of the

printed circuit planar coils. The resulting

unbalance is precisely measured using a

patented autoplex circuit. This signal is then

converted to a linear DC output voltage or

current proportional to the angle of the rotor

shaft. The digital circuit is extremely resistant to

environmental disturbances and provides

outputs compatible for use with most analog

position feedback systems.

purchasing large quantities, a pulse width

modulated digital output can be supplied as a

special configuration. Other specialized options

for volume applications include, regulated single

or bipolar excitation, extended operating ranges,

and custom uni-polar and bi-polar calibration

scaling.

standard size 15 servo/syncro mounting or

optional four hole flange mount. A shaft seal is

supplied with flange mount for applications

where protection from hostile environmental

conditions are required. RVITs offer wide

operating temperature range, infinite resolution,

and a virtually infinite cycle life.

transducers are available in a variety of versions

which provide a range of supply and output

configurations. Calibrated outputs of ±3 VDC

and 4-20 mA offer ideal flexibility for specialized

OEM designs where unique power supply and

interfacing requirements exist. Other specialized

ranges, internal regulation and custom calibrated

outputs are available for special order.

emulates a potentiometer in that the output

voltage is ratiometric to the input voltage, within

the limits of the supply specification. In addition,

the noncontact design of the RVIT provides

virtually infinite rotational life and extremely high

accuracy of ±0.25% FS.

For original equipment manufacturers,

RVIT 15’s are available with a choice of

RVIT 15-60 and RVIT 15-120i
