Yokogawa CA550 Multi-Function Process Calibrator HART Communication

Automatic input/output testing is possible by setting source values for each step for a calibration target. Calibration results such as generated value, measured value, error rate, date/time, and pass/fail are saved in CSV format in the CA550 main unit. By connecting the CA550 to a PC using a standard USB cable, the instrument can be recognized as a mass storage device for data to be transferred to the PC.

Easy-to-view Display

The CA550 features a Reflective LCD, providing improved outdoor visibility. The main display (generated/measured values) and Sub display (%, mV, Ω, etc.) allow required information at a work site to be confirmed at a glance.

Wiring information display function

A wiring diagram is displayed according to the function selected. This function allows a user to perform wiring while referring to a wiring diagram and prevents mis-wiring.

Thermocouple generation using TC Mini Plug

Using a TC Mini Plug together with a compensating lead wire enables generation of thermal electromotive force without an external RJ sensor.

Easy-to-use key operation

0%/100% keys: The source can be easily switched between 0% and 100% of range. Users can also set a desired value.

UP/DOWN keys: The output is changed in preset steps by pressing UP or DOWN key.

Operation key layout

Keys related to generation and measurement are arranged collectively to allow easy and intuitive operation.

Multi-function support allows accurate inspection of various field devices

Sources and measures DC voltage, DC current, RTD, TC, resistance, frequency and pulse signals

Corresponds to 17 types of TC standard (JIS/IEC/DIN/ASTM/GOST R)

Corresponds to 14 types of RTD standard (JIS/IEC/GOST R)

Achieves accuracy of 0.010% (DC current), 0.015% (resistance), and 0.1˚C (RTD)

Supports HART communication, including reading of HART device information, writing of LRV/URV, and trimming of analog output

Offers automatic input/output testing (program sweep) by setting source values for each step for calibration target

Saves calibration results in CSV format, including generated value, measured value, error rate, date/time, and pass/fail

Linear sweep function: Continuously Source from 0% to 100%

Step sweep function: Change output in a staircase (step) pattern by specifying number of steps

Program sweep function: Users can set desired output value (%) and number of steps

Robust and ruggedized body allows operation even in severe environmental conditions

Energy efficient design allows for longer battery life, up to 16 hours, for long term field use
