The RCA is an accessory for measuring contact RPM, linear
speeds or totalizing lengths. It needs to be plugged into a
tachometer to be funconal. It is supplied with two rubber
contact ps (one concave and one convex) and a 10 cm
linear wheel. An oponal 12-inch linear wheel is available.
When used with the , the
unit outputs 12 pulses per revoluon (PPR). The maximum
operang range of the RCA is 20,000 RPM when used with a
contact p and 12,000 RPM when used with a linear wheel.
The RCA plugs into the 3.5 mm stereo
input jack of the tachometer. Refer to
the tachometer’s operang instrucons
on how to set up the tachometer for
contact measurement of speed, rate, or
totalizaon.
Connector pinouts are shown in Figure 1.

To measure rotaonal speed
(RPM), select either a convex
or concave rubber contact p
appropriate for the measurement
to be made and install it rmly on
the sha of the RCA. Note that
the sha has a at surface that
must align with the at in the
rubber contact ps. The pointed convex (conical) p is used
for moderate to large diameter shas that are equipped with
a turned center, while the concave (inverted conical) p is
used on smaller diameter shas. The circumference of the
concave p is 1.0 inch [2.54 cm].
To make a measurement, start the rotang equipment and
carefully move the contact p against the center on the end
of the rotang sha. Keep the hand holding the RCA well
behind the back edge of the front ange of the RCA. Use only
a moderate amount of pressure to keep the rubber p in
contact with the rotang sha.

Surface speed linear rate measurements are made with
the Linear Speed Wheels which can read both direcons of
movement.
The 10 cm Linear Speed Wheel must
be pushed back onto the sha,
aligning the ats. Secure it in posion
by rmly ghtening the small machine
screw on the wheel.
The oponal 12-inch wheel also has
a slot that must engage with the pin
in the RCA sha and a locking screw
which must be ghtened.
To measure a linear surface speed and/
or total length such as a moving belt,
roll or web, rst select the Rate (Linear Contact) or Total
mode on the tachometer and set the wheel size [10 cm or
12 in.]. Hold the RCA at a right angle (90 degrees) to the
direcon of movement and gently contact the rubber edge of
the wheel against the belt or top surface of the object to be
measured. For accurate results, be sure that the wheel edge

and the direcon of travel. Only a very moderate amount of
pressure is required. Excess pressure can load the RCA sha
causing an erroneous reading and eventual wear in the
bearings of the RCA.
