1. Precision Calibration for Comprehensive Process Maintenance

The Yokogawa CA300 Series represents the pinnacle of handheld process calibration, engineered to meet the uncompromising demands of modern industrial control systems. Spanning three specialized models—CA310, CA320, and CA330—this series offers an integrated solution for the inspection, verification, and maintenance of critical control devices, including temperature controllers, industrial transmitters, process sensors, and various other essential components found in refineries, chemical plants, and manufacturing facilities worldwide. The necessity for high-accuracy tools is non-negotiable, as even marginal errors in process loops can lead to catastrophic operational failures or massive material losses. The CA300 ensures that the backbone of your automation structure remains flawlessly accurate. Its ergonomic design is not merely a convenience but a critical feature, promoting ease of use and reducing technician fatigue during long shifts in complex field environments. We recognize that investment in calibration equipment is an investment in operational safety and efficiency, and the CA300 Series is designed to justify this investment with its robust performance and exceptional longevity. This tool elevates standard calibration tasks into a verifiable, high-precision function, cementing Yokogawa’s reputation for industrial excellence.

2. Unmatched Versatility Across All Control Signals

The strength of the CA300 Series lies in its dedicated yet complementary model architecture, ensuring comprehensive coverage of all standard industrial signals. The CA310 is the voltage and current workhorse, delivering a basic accuracy of 0.015% for both source and measure functions of DC voltage and mA current, a figure that satisfies the most stringent quality control requirements. Its capability to simultaneously supply 24V loop power while accurately measuring the output signal revolutionizes transmitter calibration, significantly reducing the need for auxiliary equipment. Complementing the CA310 are the temperature specialists: the CA320 and CA330. The CA320 is dedicated to Thermocouple (TC) signals, supporting 16 types including JIS, IEC, DIN, ASTM, and GOST R standards, and offering typical accuracy of 0.5°C for Type K. The CA330, an expert in Resistance Temperature Detectors (RTD), handles 14 types and supports 2, 3, and 4-wire configurations, achieving typical accuracy of 0.3°C for PT100. This modular yet cohesive design guarantees that whether you are dealing with a standard 4-20 mA loop or a highly specialized RTD sensor, the CA300 Series has the dedicated, high-precision functionality required for the task.

3. The CA310: Core Accuracy and Loop Power

The CA310 stands out as an indispensable tool for electrical process technicians. Beyond its stellar 0.015% basic accuracy for DC current, the CA310 integrates features that streamline workflow dramatically. A prime example is the embedded 24V loop power supply, which eliminates the need to carry external power sources when calibrating 4-20 mA current loops in the field. This capability, combined with simultaneous high-accuracy measurement, allows for rapid diagnosis and calibration of two-wire transmitters, minimizing downtime. Furthermore, the CA310 includes a built-in 250 $\Omega$ resistance, a crucial component required for communicating with HART/BRAIN smart devices. This seemingly small feature underscores Yokogawa’s understanding of real-world calibration challenges, providing full support for advanced digital process control infrastructures. The CA310 also includes a specialized 20 mA SIMULATE (SINK) function, essential for testing control system inputs by simulating the current draw of a field device. These combined features make the CA310 the definitive instrument for commissioning and maintaining all current and voltage-based control loops.

4. Dedicated Temperature Mastery with CA320 and CA330

Temperature calibration demands instruments that can handle a vast array of sensor types and standards. The CA320 and CA330 models excel here, providing dedicated precision for TC and RTD signals, respectively. The CA320 offers comprehensive support for 16 standard thermocouple types, ensuring compatibility across diverse international industrial installations. Crucially, it also features a millivolt (mV) source function, which allows for calibration of non-standard or older TC types, extending its utility beyond the predefined list. For resistance-based measurements, the CA330 is peerless. Its ability to simulate and measure 14 types of RTD, coupled with support for 2, 3, and 4-wire connections, ensures highly accurate resistance compensation, a vital factor in minimizing temperature measurement error. Specific applications include: calibrating process temperature transmitters, verifying the accuracy of control loops linked to furnaces and reactors, and inspecting field temperature sensors before installation. Both models also function as accurate digital thermometers, measuring the sensor output directly, adding another layer of versatility to their operational profile.

5. Advanced Sweep Functions: Efficiency in Linearity Testing

To properly calibrate control devices like PID controllers and especially motorized control valves, technicians must verify linearity across the entire operational range (0% to 100%). The CA300 Series provides a suite of advanced sweep functions designed precisely for this task, automating and standardizing the testing process. The Step Sweep Function automatically sources signals in 25% increments (0%, 25%, 50%, 75%, 100%), allowing selection of step times (15, 30, 45, or 60 seconds) to match the response time of the tested device, thereby optimizing efficiency. The Linear Sweep Function sources the signal continuously from 0% to 100% over the selected time, which is essential for detailed linearity checks and charting. For quick operational checks, the Span Check Function is invaluable, switching the source instantaneously between 0% and 100% with a single touch. This feature is particularly useful for rapidly inspecting the open and close operation of actuators and control valves, confirming they reach their full travel limits swiftly and accurately. These integrated automation features transform lengthy, manual processes into fast, repeatable, and documented procedures.

6. Ergonomics and Durability: Designed for the Field

Yokogawa engineers recognize that calibration tools are subjected to harsh industrial environments. The CA300 Series is built for resilience, encased in a rugged body designed to withstand the inevitable bumps and splashes of fieldwork. Beyond physical toughness, the user interface is optimized for efficiency. An ergonomic design ensures comfortable, one-handed operation. A crucial usability feature is the Addition of Sub Display, which supplements the main display. While the main display shows the setting value for the source function, the sub-display simultaneously shows the resulting span percentage, the output value of voltage or resistance, or other relevant secondary data. This eliminates the need to toggle between screens, greatly enhancing productivity and reducing the chance of transcription errors during documentation. The combination of a friendly user interface, robust build quality, and intelligent display features positions the CA300 Series not just as a tool, but as a reliable partner in industrial maintenance, ready for any environment, from indoor control rooms to outdoor plant floors.
