The Mitutoyo ABSOLUTE 500 series caliper with exclusive AOS
sensor technology is a Digimatic caliper that is made of durable
hardened stainless steel and uses Mitutoyo’s ABSOLUTE linear
encoder technology, which allows you to “set and forget” the
origin and measure in awkward or difficult locations. This series
also utilizes the patented Advanced Onsite Sensor (AOS) offering
improved measurement dependability by increasing resistance to
harsh workshop conditions.
The New electromagnetic inductive (AOS) sensor has improved
resistance to environmental conditions such as dirt, oil and
water that can cause false readings. This new feature will
improve quality control and productivity in your workplace.
This digital caliper has LCD readout and function control
buttons on the caliper face, including Origin to set and retain
the original measuring point, and Zero/ABS (Absolute Scale) to
zero-set the LCD display. It uses the metric measuring system.
Although identical to dial and vernier calipers in its ability
to make precise measurements, the digital caliper also has an
LCD, which clearly shows values and increases reading reliability
over the other types, and reflects all ABSOLUTE system
activities. The Absolute Scale (ABS) function tracks the origin
point you set, even after shutoff. Once on again, the caliper can
immediately start measuring, without zero resetting or concern of
over speed errors. The LCD can be "zeroed out" before making and
comparing incremental measurements without having to subtract the
first measurement from the second.
The calipers use the ABSOLUTE electrostatic capacitance linear
encoder which helps prevent over speed errors. They measure outer
diameter (OD), inner diameter (ID), depth, and step, where the
butt end of the fixed jaw measures one end of a work piece before
its upper/lower or inner/outer "steps" are measured. LCD
Resolution is 0.01mm. Also included are origin-setting,
zero-setting, and on/off automatic shutoff function buttons. A
Digital LCD Data Reading Hold function is available with the
optional Data Hold Unit (sold separately). An alarm alerts the
user to low voltage and scale contamination and counting value
composition errors. A rolling thumb wheel makes fine adjustments
and a thumb screw locks the scale’s position. Response speed is
unlimited. Each caliper includes, and is powered by, one SR44
silver oxide cell battery that lasts approximately 3.5 years with
continuous normal use.
Calipers measure the distance between two sing sides of an
object. They make inside, outside, depth, or step measurements,
according to their type. Calipers are commonly used in
architecture, metalworking, mechanical engineering, and
machining. The simplest calipers have two legs to mark the two
points and require a ruler to take the measurement. More complex
calipers use two sets of jaws instead of legs and have up to two
graduated scales. Vernier, dial, and digital calipers give direct
and accurate readings and are functionally identical, having a
calibrated scale with a fixed jaw, and another jaw with a movable
pointer that slides along the scale. The vernier caliper has a
scale sliding parallel to the main scale for an additional,
fractional reading to improve measurement precision. The dial
caliper has a circular dial with a pointer on a toothed gear rack
replacing the second vernier scale. As with the vernier, this
second measurement is added to the reading from the main scale to
obtain the result. The digital caliper takes a differential by
zeroing the display at any point along the slide, with an LCD
that displays a single value in English and/or metric units.
Mitutoyo manufactures precision measuring tools, metrology
equipment, and systems. The company was founded in Tokyo in 1934
and formed Mitutoyo America Corporation in 1963, which is
headquartered in Aurora, IL.
