Grind, Measure andAssembleP R E C I S I O N
Our mastery of the basics of crafts manship is the proof of reliability

M E AS UR I NG
Through manufacturing watches that require absolute precision,
CITIZEN has continued to refine its technologies to "grind,""measure" and "assemble."
These three technologies are the basics of craftsmanship.
It is no exaggeration to say that CITIZEN is the only manufacturer ofmeasuring instruments that possesses all three of these technologies.
Our technical abilities, which have been proving their worth inmeasurements of watch components requiring high precision in
micron units, have become the proof of reliability,

With this method, the absolute position is read instantaneously when the power is turned on, thereby eliminating
the need for master adjustment, which has conventionallybeen required each time.
This method reduces the setup time for each use and improves your work efficiency.

This series of sensors achieves high durability owing to the W-bearing structure and die-cast body. The series also eliminatescounting errors by adopting the absolute method.
In addition to a minimum resolution of 0.5 µm (SA-S510, SA-S510/03N), high resolution products with a resolution of 0.1 µm are alsoavailable (SA-S110, SA-S110/03N). The series demonstrates superb capabilities in various measuring situations.

A long stroke of 32 mm extends the measurement range while maintaining high durability.

An ultra-long stroke of 50 mm easily accommodates measurements of large components.

Air purge technology provides the ultimate environmental performance.
The body's inner pressure is raised by air-purging, which prevents foreign objects from invading. These sensors exhibit
strong performance in severe environments where they are exposed to liquids such as permeable oil, coolant liquids, andcutting fluids.

You can measure the over-pin diameter, large diameter, and small diameter using the BST-2B or BST-1B (3LB) inner diameter measuring instruments and a special-order contact point. Although different measurement methods are used for odd
and even numbers of teeth, the following gives some measurement examples.
* Since these measurements are comparative measurements against a master (reference work), a master workpiece isrequired.

Over-pin diameter

condition
For both even and odd numbers of teeth, measurement
can be performed using a twopoint-type ball contact point.
However, to ensure that thecontact point does not touchthe large diameter surface, youmust consider the ball diameterat the tip or whether the ballhas been cut into a D-shape.

to come into contact with thelarge diameter surface, it isnecessary to select the balldiameter so that it does notinterfere with the gear surface.
Our standard contact point has

Small diameter

For an even number of teeth,
two R-shaped contact points
are used. For an odd numberof teeth, two ball contact points
and an R-shaped contact point
are used.

Our lineup of horizontal stands can be used to measure inner and outer diameters. By attaching SA series
displacement sensors or Mu-METRON to these stands,
you can obtain measurement values with minimal measurement error. In addition, you can measure abnormallyshaped workpieces or grooves by using special contact
points. Use the H-2 series to measure outer diameters
and the BST series to measure inner diameters.
