Pressure calibrator CA700

voltagecurrentsignal

The CA700 Pressure Calibrator is equipped with a silicon resonant sensor that uses Yokogawa proprietary DPharp technology. The CA700 has a basic accuracy of 0.01% of reading on pressure measurement and 0.015% of reading on Current/Voltage source/measurement, which makes it the most accurate calibrator in the portable calibrator class. Field Calibration of Differential Pressure and Pressure Transmitters Calibration of pressure transmitters is required to accurately measure the input and output values and to calculate the error rate. The CA700 ensures reliable calibration with its function to accurately measure the input and output values of pressure and current. Additionally its embedded calibration procedures enable users to perform certain calibration following the prescribed procedure. Pressure Switch Test A pressure switch test measures the pressure at the time when the contact opens and closes and the resistance at the time when the dead band contact closes. A test procedure is embedded to enable users to carry out a test following the prescribed procedure. Check and I/O Adjustment of an Electro-pneumatic Converter Input and output adjustment of an electro-pneumatic converter is carried out by applying rising and falling currents of 0, 25, 50, 75, and 100% of the span. A reliable test can be carried out with the CA700 that has a 4-20 mA step function for signal generation and a capability to accurately measure the generated pressure.
