calibrator specifically designed for the calibration of differential
pressure and pressure transmitters, which are widely used in plant
processes these days and are improving in terms of accuracy and
functionality. The CA700 has achieved the highest accuracy and
widest range in the portable class, enabling field calibration with
greater accuracy than ever before.

n High Accuracy and Long Stability
The highest accuracy in the portable class achieved with a
silicon resonant sensor
The CA700 employs a silicon resonant pressure sensor with which Yokogawa
has achieved the highest accuracy in the portable class of a 0.01% of reading
for pressure measurement and 0.015% of reading for current and voltage
measurement. This calibrator is ideal for input and output testing of differential pressure and pressure transmitters in that it correctly measures the input
and output accuracy and calculates the error rate.
n Rangeability
Has the highest resolution and the widest range in its class
The CA700 has achieved a resolution of 0.001 kPa (200.000 kPa range)
which is 10-fold higher than that of general field calibrators. The excellent
sensing characteristics of a silicon resonant sensor make it possible to
achieve a very wide range and enable one CA700 calibrator to replace
multiple field calibrators.
n User Support
Strong support for field calibration and maintenance work
Calibration procedures for differential pressure and pressure transmitters
are embedded, so routinely used as 50-percent step, up-and-down, 5-point
calibration and 25-percent step, up-and-down, as well as 9-point calibration
can be performed right out of the box. Calibration operation can be sped up
by following the navigation instructions, resulting in increased efficiency of
field work. Measurement data is automatically recorded to the calibrator so it
can be saved to a USB memory stick or transferred to a PC as text data using
a USB cable. Input and output values, error rate, date and time, and pass or
fail can be displayed on a PC monitor.

n Field Use
IP54 waterproof and dustproof robust case enables use of
this calibrator in harsh environments
Calibration of pressure transmitters is usually carried out in harsh environments where there are many pipes and handrails or in wet areas. The CA700
has a robust case designed according to the IP54 waterproof and
dustproof standards. A shoulder strap can
be attached to the calibrator to make
it easy to carry around in the field. In
addition, an easy-to-read LCD and tilt
stand suitable for outdoor work exposed
to direct sunlight extend the range of
use of this calibrator from indoor bench
use to outdoor field use.
