1. Defining Precision for Critical Industrial Pressure Measurement

The Yokogawa CA700 Pressure Calibrator is not merely a tool; it is the industry benchmark for portable, high-accuracy pressure calibration. In process plants—where variables like flow, level, and temperature are often derived from pressure—the integrity of pressure transmitters is paramount to maintaining plant health and safety. The CA700 is specifically engineered for this crucial task, offering an unparalleled basic pressure measurement accuracy of 0.01% of reading, placing it firmly at the top of the portable calibrator class. This level of precision ensures that periodic calibration—an absolute necessity for reliable transmitter performance—is conducted with the highest possible confidence. The CA700’s superior resolution, reaching up to 0.001 kPa in the 200 kPa range, allows technicians to detect the smallest drifts and inaccuracies, thereby preventing operational errors before they escalate. For maintenance and commissioning engineers, the CA700 guarantees that every reading is trustworthy, turning a complex, critical task into a streamlined and highly verifiable process.

2. Unrivaled Precision Powered by dPharp Sensor Technology

The extraordinary accuracy of the CA700 is rooted in Yokogawa’s patented dPharp sensor technology, the same high-quality, reliable technology used in their world-class industrial pressure transmitters. This core innovation provides a stability and sensitivity unmatched by competing portable devices. The 0.01% accuracy is maintained across multiple pressure ranges, enabling maximum resolution regardless of the specific application or required span. Pressure is a critical force in every plant, and instruments must perform reliably under the most demanding conditions. The CA700 supports various pressure types—low, medium, and high—and is designed to integrate seamlessly with a range of selectable, high-performance hand pumps for field use. This synergy between advanced sensor technology and robust field integration ensures that the CA700 provides lab-grade accuracy wherever the job takes you, confirming its status as the most accurate portable calibrator available today.

3. Comprehensive Electrical Functionality for Transmitter Checks

While renowned for its pressure performance, the CA700 also delivers comprehensive electrical source and measurement capabilities crucial for complete pressure transmitter and loop checks. The instrument features a basic accuracy of 0.015% of reading for Current/Voltage source and measurement, making it highly effective for verifying the electrical output of a transmitter. Specialized functions greatly simplify field maintenance: the 4-20mA step function allows for precise signal generation testing across the span. Furthermore, the CA700 can function as a 20mA Simulator to effectively carry out loop tests, isolating potential issues within the control system input. For technicians working with smart instrumentation, the inclusion of a 250-ohm resistor is vital, providing the necessary communication impedance for interacting with HART and BRAIN protocols. This integration means the CA700 acts as a single, powerful device capable of calibrating both the physical pressure input and the electrical signal output of a transmitter, dramatically enhancing field efficiency.

4. Dedicated Routines for Robust Field Documentation and Audits

Effective calibration goes beyond simply taking a measurement; it requires meticulous documentation for compliance and quality control. The CA700 is perfectly suited for this, supporting customizable, built-in “AS-FOUND” and “AS-LEFT” routines. These routines systematically guide the technician through a pre-defined calibration procedure, automatically documenting the device’s condition before any adjustments (“AS-FOUND”) and the final, corrected condition after adjustments (“AS-LEFT”). This capability transforms field work into auditable, standardized practice, eliminating manual data entry and potential human error. Furthermore, the CA700 can be used as a data logger, securely storing calibration results for subsequent retrieval, or as a USB storage device for easy data transfer to a PC. This seamless documentation capability is particularly crucial for industries like pharmaceutical, chemical, and nuclear, where regulatory compliance hinges on verifiable calibration records.

5. Extending Pressure Range with the PM100 High-Pressure Module

The versatility of the CA700 is significantly extended through its compatibility with specialized external modules. Crucially, the introduction of the PM100 high-pressure module effectively increases the calibrator’s operational pressure range up to a formidable 2300 PSI (approximately 160 bar). This expansion is critical for applications involving high-pressure boiler systems, hydraulic control lines, and gas pipelines, where standard portable calibrators typically fall short. Importantly, even when utilizing the PM100 module to access these elevated pressure limits, the CA700 maintains its fundamental, best-in-class accuracy of 0.01% of reading. This ensures that the high-pressure measurement remains as precise and reliable as a standard low-pressure reading. The seamless integration and consistent accuracy across the full range—from vacuum to 2300 PSI—make the CA700 an indispensable, high-utility device for process plants operating across a wide spectrum of pressure conditions.

6. Built for Survival: Durability and Seamless Field Integration

Industrial environments are inherently challenging, demanding instruments that can withstand dust, moisture, and rough handling. The CA700 is designed with this reality in mind, featuring an IP54 dust and waterproof case that protects its sensitive components from harsh environmental factors. Its rugged construction ensures reliability and longevity, minimizing repair and replacement costs. Despite its advanced capabilities, the CA700 remains lightweight and truly portable, making it easy for technicians to transport across vast plant areas. A built-in stand further enhances field usability, allowing the unit to be positioned securely on a workbench or grating for hands-free operation. Moreover, the CA700 supports integration with FieldMate 3.03, Yokogawa’s comprehensive device management software. This integration allows the CA700 to function as part of an all-in-one calibration system, streamlining setup, calibration execution, and data management into a single, cohesive workflow, solidifying its role as a rugged, smart field partner.
