Yokogawa PM100 External Pressure Sensor: The Definitive High-Pressure Calibration Module

Elevating Pressure Calibration to Unprecedented New Heights

The world of industrial process control demands absolute precision, especially when dealing with high-pressure systems where failure is not an option. For years, the Yokogawa CA700 Process Calibrator has set the standard for accuracy in field environments. However, to meet the specialized demands of ultra-high-pressure applications, Yokogawa engineered the PM100 External Pressure Sensor. This dedicated module is not merely an accessory; it is a profound extension of the CA700’s capabilities, designed to extend the measurable pressure range up to an astounding 70 MPa (10150 PSI). This seamless integration allows maintenance and calibration technicians to perform comprehensive, high-stakes pressure verification routines without sacrificing the superior accuracy and reliability that the Yokogawa name guarantees. The PM100 is purpose-built for environments requiring rigorous compliance and peak performance, ensuring that every measurement, from the lowest vacuum to the highest pressure, is certifiably correct. This module’s plug-and-play design ensures minimal setup time, allowing technicians to rapidly deploy high-pressure calibration capabilities directly in the field, turning the versatile CA700 into a truly universal pressure calibration standard. The need for multiple, specialized pressure instruments is eliminated, consolidating tools and simplifying inventory management for large industrial sites globally.

Yokogawa dPharp: Precision Down to the Millipascal

At the core of the PM100’s extraordinary performance lies Yokogawa’s proprietary dPharp sensor technology, the same sophisticated architecture found in the company’s world-renowned EJA/EJX series pressure transmitters. This pedigree ensures an inherent stability and reliability that few competitors can match. The PM100 delivers an industry-leading basic measurement accuracy of 0.01% of reading, a specification typically reserved for laboratory-grade devices. Crucially, the PM100 achieves an exceptional resolution down to 0.0001 MPa (or 0.015 PSI) in its measurement ranges, allowing users to detect the most minute pressure fluctuations and perform highly detailed linearity checks. This high resolution is critical for commissioning new transmitters or fine-tuning existing ones where small deviations can significantly impact process efficiency and safety. By leveraging the dPharp technology, the PM100 minimizes the effects of temperature and static pressure variations, which are common sources of error in less advanced sensors. This robust design means that the accuracy specified in the data sheet is the accuracy delivered on the plant floor, providing technicians with total confidence in their calibration reports. The ability to maintain this level of precision in a portable, rugged field unit is what truly distinguishes the PM100 in the crowded calibration market. This commitment to maintaining lab accuracy in harsh environments is a testament to Yokogawa’s engineering philosophy.

Flexibility is paramount in the calibration world, where requirements can shift dramatically from one service point to the next. The PM100 is engineered to address this variability through its innovative multi-range configuration. Each PM100 unit is equipped with three selectable pressure ranges, effectively providing three high-accuracy calibrators in a single, compact module. For moderate high-pressure needs, one option covers the 7 MPa, 10 MPa, and 16 MPa ranges (1015 PSI to 2320 PSI). For the most demanding applications, a second option provides ranges up to 25 MPa, 50 MPa, and the maximum 70 MPa (10150 PSI). This triple-range capability allows technicians to optimize the sensor’s performance for the specific test being performed, ensuring maximum resolution and stability at lower pressures while still retaining the capability for extreme measurements. The user can switch between these ranges effortlessly via the CA700’s intuitive interface, ensuring that the appropriate level of detail is captured for every calibration point. This intelligent design eliminates the need to purchase, transport, and manage multiple discrete pressure modules, streamlining the calibration kit and reducing the overall cost of ownership. The ability to switch ranges on the fly makes troubleshooting and complex loop testing significantly faster and more accurate, directly contributing to minimized plant downtime.

Seamless Integration With CA700 For Mobile Excellence

The PM100 is designed as a perfect companion to the Yokogawa CA700, ensuring a synergistic performance that enhances the functionality of both devices. The module plugs directly into the top of the CA700 unit, establishing immediate communication and drawing power from the main calibrator. This seamless physical and electronic link means no extra batteries or cables are needed for the pressure module itself, enhancing the portability and ruggedness of the combined unit. Compatibility is assured for CA700 units running firmware version 1.20 or later; if an earlier version is detected, a simple and quick firmware update prepares the calibrator to communicate with the advanced sensor. Once connected, the CA700’s large, clear display and powerful processing capabilities manage all pressure readings, unit conversions, and calibration data logging. The PM100’s integration means it fully utilizes the CA700’s internal routines, including the vital “AS-FOUND” and “AS-LEFT” functions which automate compliance reporting by meticulously documenting the state of a device both before and after adjustments. This combined system represents a best-in-class mobile laboratory, capable of delivering certified results in the most challenging industrial environments, from oil refineries to power generation plants.

Critical High-Pressure Transmitter Calibration: Solved Instantly

The primary application for the Yokogawa PM100 is the highly demanding task of field calibration for high-pressure transmitters. In many industries, pressure transmitters operate near their maximum limits, and accurate calibration at these ranges is essential for maintaining safety barriers and maximizing process yield. When connected to the PM100, the CA700 system ensures reliable calibration by accurately measuring both the pressure input (via PM100) and the corresponding current/voltage output (via CA700’s electrical functions) of the transmitter. The embedded calibration procedures within the CA700 guide the user through standardized, complex routines, minimizing human error and ensuring consistency across an entire site. Specific applications include: calibrating hydraulic system sensors, verifying wellhead pressure in oil and gas operations, checking the performance of high-pressure boiler feed pump sensors, and ensuring the reliability of safety-critical high-pressure relief valves. The PM100’s compatibility extends the CA700’s utility far beyond simple field checks, enabling full system verification and regulatory compliance testing for high-stakes instrumentation, making it an indispensable tool for maintenance teams focused on uptime and safety integrity. The ability to handle extreme pressures with such high accuracy simplifies complex regulatory audit trails.

Robust Design Ensures Reliable Performance In Any Environment

The PM100 is built to withstand the realities of field service. Its robust construction complements the already rugged design of the CA700, ensuring that the combined instrument maintains the high durability standards expected of Yokogawa equipment. While the PM100 is the sensor, its attachment to the CA700 ensures that the overall system benefits from the CA700’s IP54-rated dust and water-proof housing, protecting the sensitive internal electronics from ingress of moisture and dirt common on plant floors. Furthermore, the PM100 utilizes the same advanced materials and construction techniques as Yokogawa’s industrial transmitters, ensuring resistance to vibration and mechanical shock. Its compact form factor adds minimal bulk and weight to the CA700, preserving the portability and ergonomic handling that technicians rely on for long days of calibration work. This focus on ruggedness means technicians can rely on the PM100 to deliver consistent, accurate results whether they are working in a frigid northern pipeline or a humid, dusty refinery in the desert. The long-term reliability of the PM100 translates directly into reduced total cost of ownership, as the module requires minimal servicing and replacement, standing up to years of continuous, demanding use in harsh industrial settings.
