CDS 820 Chart Drive System

Disc Chart Drives Type 725

 

CDS 820 Chart Drive System

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.

Disc Chart Drives Type 725

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 OF ROTATION Unless otherwise specified, Disc Chart Drives are furnished with counter-clockwise rotation shft (seen from above).
TEMPERATURE
Normal temperature range:
Low temperature:
High temperature:
-4º to +120ºF
as low as -40ºF
up to +450ºF

DISCS Not supplied.
ACCESSORIES A rewind key is supplied with each movement.
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.
