 Pressure Calibrator

Yokogawa CA700

 The CA700 (Model CA700-E-01 | CA700-E-02 | CA700-E-03) Pressure Calibrator 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.

  • CA700-E-01: 0 to 200 kPa
  • CA700-E-02: 0 to 1000 kPa
  • CA700-E-03: 0 to 3500 kPa

 It also has the highest resolution and widest range of any portable instrument, with a resolution of 0.001 kpa (200.00 kpa range) and a resolution of 0.0001 psi (at the 29 psi range). A high pressure module, the PM100, is now available, that effectively increases the pressure range of the CA700 to 2300 PSI, all the while maintaining the same basic accuracy of 0.01%.

Pressure is one of the most important and commonly measured forces in industrial plants and sites. Other commonly measured forces, such as temperature, flow and level, can all be derived from pressure. Because of this, pressure transmitters are especially crucial for maintaining the health and safety of plant operations. For a pressure transmitter to perform reliably, periodic calibration of these devices is absolutely necessary. Yokogawa's pressure calibrators are specifically suited for this task due to their

Application Notes

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.

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..

 

Two-wire Transmitter Loop Check

 DC mA signals can be measured by supplying power to the transmitter from a 24 V DC power supply. DC mA signal measurement and zero-point check can be performed with an accuracy of 0.015% of the reading.

 A 250-ohm resistor for HART and BRAIN communication is included in this calibrator so there is no need to attach an external resistor when connecting to a handy terminal

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.

20 mA SIMULATE (Two-wire Transmitter Simulator)

 The CA700 can also be used as a transmitter simulator to carry out a loop test.

 It can absorb (SINK) the set current from an external voltage generating device (e.g., a distributor system or PLC) of instrumentation equipment.

Input Command Check and Adjustment of Recorders and Controllers

 Instrumentation loop test and operation/command check can be performed by sourcing DC 1-5 V / 4-20 mA instrumentation signals with an accuracy of 0.015% of the reading.

 Furthermore, two patterns of linear sweep and step sweep can be selected (the sweep time can be specied from 15, 30, 45, and 60 sec)
