The Yokogawa CA700 Pressure Calibrator has a basic accuracy of 0.01% of rdg on pressure measurement and 0.015% of rdg on Current / Voltage of the source and measurement portions of the CA700. The CA700 is the most accurate calibrator in the portable calibrator class. It also has the highest resolution and widest range of any hand held portable in its class with resolution of 0.001 kpa (200.00 kpa range) and a resolution of 0.0001 psi (29 psi range)
Applications for the Yokogawa CA700 include:
- Field calibration of differential pressure and pressure transmitters
- Pressure switch test
- Check and I/O adjustment of an electro-pneumatic converter
- 20 mA SIMULATE (two-wire transmitter simulator)
- Two-wire transmitter loop check
- Input command check and adjustment of recorders and controllers
