PR3860 High Temperature Pressure Transmitter: Accurate Measurement Where Heat Meets Precision

Reliable Pressure Measurement for High Temperature Applications

Many industrial processes operate in extreme temperatures where standard pressure transmitters simply cannot perform reliably. From engine testing and steam systems to chemical processing and energy production, accurate pressure measurement becomes even more important as temperatures rise.

The PR3860 High Temperature Pressure Transmitter  has been engineered specifically for these challenging environments. Designed to provide accurate, stable pressure measurement at elevated temperatures, the PR3860 combines robust construction with excellent long-term reliability. An intrinsically safe version is also available with ATEX and IECEx certification, making it suitable for hazardous area installations worldwide.

Why High Temperature Pressure Measurement Matters

High temperatures can significantly affect the performance of standard pressure transmitters. Excessive heat may introduce measurement errors, reduce sensor life and increase maintenance requirements.

The PR3860 is designed to overcome these challenges, delivering dependable pressure measurement even in applications where conventional sensors may struggle. This enables engineers to maintain process efficiency, improve product quality and reduce unplanned downtime.

Accurate and Stable Performance

Pressure measurement plays a vital role in maintaining safe and efficient industrial processes.

The PR3860 delivers excellent measurement accuracy, repeatability and long-term stability, giving operators confidence in the data they rely on every day. Accurate pressure readings help optimise process control, protect valuable equipment and support consistent manufacturing quality.

Its durable construction also helps ensure reliable operation in demanding industrial environments where high temperatures are a constant factor.

Intrinsically Safe for Hazardous Areas

Many high temperature applications are located in hazardous environments where flammable gases or vapours may be present.

To meet these requirements, the PR3860 is available as an intrinsically safe pressure transmitter with ATEX and IECEx certification. This version allows the transmitter to be safely installed in hazardous areas while maintaining the same high levels of accuracy and reliability.

The combination of elevated temperature capability and international hazardous area approvals makes the PR3860 an excellent choice for global process industries.

Flush Diaphragm Option for Hygienic Applications

For industries where cleanliness is just as important as accuracy, the PR3860 is also available with a flush diaphragm.

Unlike conventional pressure connections that can create small cavities where product residue may collect, a flush diaphragm sits level with the process connection. This helps eliminate areas where media can become trapped, making cleaning easier and reducing the risk of contamination.

This design is particularly beneficial for hygienic and sanitary applications, including:

• Food and beverage processing
• Pharmaceutical manufacturing
• Biotechnology
• Dairy production
• Brewing and beverage production
• Clean-in-place (CIP) and Sterilise-in-place (SIP) systems

The flush diaphragm option allows accurate pressure measurement while supporting high hygiene standards throughout the process.

Typical Applications for the PR3860

The PR3860 is suitable for a wide range of industrial applications where high temperatures, hazardous environments or hygienic process requirements demand reliable pressure measurement.

Typical applications include:

• Steam systems
• Industrial boilers
• Heat exchangers
• Chemical processing
• Petrochemical plants
• Oil and gas production
• Power generation
• Hydrogen processing systems
• Engine development and testing
• Industrial furnaces
• Hydraulic systems operating at elevated temperatures
• Process manufacturing
• Food and beverage processing
• Pharmaceutical production
• Research and development facilities

Its versatility makes it an excellent choice for both OEM equipment manufacturers and end users requiring dependable pressure measurement in demanding operating environments.

Built for Industrial Reliability

Industrial environments demand sensors that continue performing under constant thermal stress.

The PR3860 has been engineered to withstand these conditions while maintaining consistent measurement accuracy. Its rugged construction helps reduce maintenance requirements and supports a long operational life, even in applications involving continuous exposure to elevated temperatures.

For engineers, this means greater confidence in system performance and reduced downtime caused by sensor replacement or recalibration.
