The Yokogawa CA310 Voltage/mA Process Calibrator simultaneously supplies a 24V loop power and measure output signal with an accuracy of accuracy 0.015%. The sub display shows value of voltage source and span %. The CA310 features step sweep, linear sweep, manual step and span check source patterns.
Yokogawa CA310 Voltage/mA Process Calibrator Features:
- CA310 Volt mA Calibrator:
- 0.015% basic accuracy
- 20mA SIMULATE (SINK) function
- HART/BRAIN comm. resistance (250Ω) embedded
- Segment LCD display
The Yokogawa CA310 is a Volt mA calibrator. The CA300 series process calibrator is a high accuracy source and measure portable handheld calibrator used to inspect and maintain the accuracy of control devices such as temperature controllers, temperature transmitters, temperature sensors and other process devices which are used in process plants, industry machinery and manufacturing. The CA310 voltage and current simulate model is capable to execute a loop check by simulating a transmitter, sinking the current signal from the external source. It achieves the high accuracy 0.015% of setting to source 4mA to 20mA. DC mA signals can be measured by supplying power to the transmitter from a 24V DC power supply. DC mA measurement and zero-point check can be performed with an accuracy of 0.015% of 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.
