Accurate
The timing of the CDS 820 is based on the inherent precision
of the quartz movement concept.
Engineered and manufactured by SONCEBOZ. Scrupulous attention
to detail resulted in a unit with no axial
output shaft side play or angular backlash. Thus greatly
ensuring an exact pen stroke documentation. |
Versatile
The CDS 820 incorporates 11 switch selectable
speeds which make it usable for different applications.
The universal mounting plate makes
the CDS 820 fit in all major brands of recorders. No additional
standoffs are needed. Retrofit/conversion can be performed easily
in a shop or in the field. A 1/4" diameter output shaft
with flat and the threaded Foxboro shaft are available from
stock. Other shafts are available
upon request. |
Reliable
The high quality of the CDS 820 makes it the most trouble free
of any available chart drive. A 1.5 alkaline
or a 3.6 lithium <<C>>
battery can be used to power the chart drive. It allows the
unit to keep operating in a prolonged duration of low temperautres.
The battery compartment is separated from the drive mechanism.
A sturdy housing made of durable material and sealed by an acid
resistant 0-ring provides a hermetic enclosure. The CDS 820
is freezer tested to a temperature of
-40º F. |
Convenient
The field technicians requested the important new features of
the CDS 820. A rugged rotating speed selector for 11
speeds. Fast test speeds,
60 min. and 96 min. rovolution. All documentation speeds to
as slow as 32 days / revolution. An <<off>>
position saves battery life. A pulsating red status light
indicates that the unit is working. Hence a time saver, eliminating
double checking of chart movement. This is particularly valuable
in applications requiring slow rotational speeds. A body
pilot is locating the CDS 820 on the mounting plate.
Removing 3 screws permits exchange of chart drive. No
recalibration is necessary. |

| CHARACTERISTICS |
This
Chart Drive was designed to operate under difficult conditions.
It is of robust construction, and the movement itself is protected
by a cover with a sealing gasket and spring loaded washers.
The output torque is much greater than that of other chart drives,
e.g. 24 oz/in after 8 days run at 1 rev./24 hous. |
| DRIVE |
A
high quality clockwork movement with an 11 jewelled lever escapement.
|
| SYNCHRONOUS
MOTOR DRIVE |
Can
be obtained with the same overall dimensions. Please write for
futher details. |
| DIRECTION

| MAINTENANCE |
All
movements are carefully oiled before leaving or factory, but
they should be reoiled periodically, depending on the conditions
under which the movements function. |
| MOUNTING |
When
ordering in large quantities (1000 or more), Mounting Plate
and Output Shaft can be adapted to specific requirements. |
