In industries where processes operate under extreme heat and pressure, having robust and reliable instrumentation is essential. At ESI Technology, we specialise in advanced pressure measurement solutions that meet the toughest challenges faced by our customers worldwide. One of our flagship products for high-temperature environments is the PR3860 High Temperature Flush Diaphragm Pressure Transmitter – designed specifically for applications where standard transmitters simply cannot perform.

What is the PR3860 High Temperature Flush Diaphragm Pressure Transmitter?

The PR3860 High Temperature Flush Diaphragm Pressure Transmitter is a precision-engineered device designed to provide accurate and stable pressure readings in demanding environments. Built with a flush diaphragm, it allows direct contact with the media, preventing blockages and build-up that often compromise traditional pressure transmitters. Its high-temperature capability makes it particularly suited for industries such as:

• Chemical and petrochemical processing

• Food and beverage production

• Pharmaceutical manufacturing

• Power generation

• Oil and gas

By combining high performance with robust construction, this transmitter ensures reliable results in processes where extreme heat and cleanliness are critical.

Key Features and Benefits

At ESI Technology, we understand that each industry faces unique challenges. The PR3860 High Temperature Flush Diaphragm Pressure Transmitter has been designed with features that deliver outstanding value across applications:

• High temperature capability – Specifically engineered to operate in environments where media temperatures exceed the limits of conventional sensors.

• Flush diaphragm design – Prevents clogging, ideal for viscous, crystallising, or contaminated media.

• Durable construction – Built from high-grade stainless steel and corrosion-resistant materials to ensure long-term performance.

• Accuracy and stability – Provides consistent, repeatable results, reducing downtime and enhancing process control.

• Customisable configurations – Available with a wide range of pressure ranges, electrical connections, and process fittings to meet individual customer requirements.

These features make the PR3860 High Temperature Flush Diaphragm Pressure Transmitter a trusted choice for engineers who demand reliable instrumentation in harsh conditions.

Why Choose a Flush Diaphragm Pressure Transmitter?

Traditional pressure transmitters can struggle in applications involving thick, sticky, or abrasive media. When residue builds up on the sensing element, it leads to inaccurate readings and potential equipment damage. The flush diaphragm design of the PR3860 High Temperature Flush Diaphragm Pressure Transmitter eliminates these problems by offering:

• Easy cleaning – Smooth diaphragm surface prevents product build-up.

• Reduced contamination risks – Essential in food, beverage, and pharmaceutical industries where hygiene is a priority.

• Extended service life – Less wear and tear compared to recessed sensors exposed to clogging.

This makes it an excellent choice for maintaining both process efficiency and regulatory compliance.

Applications Across Industries

The PR3860 High Temperature Flush Diaphragm Pressure Transmitter has proven reliability in a wide range of sectors:

• Food and beverage – Measuring pressures in cooking, sterilisation, and pasteurisation processes.

• Pharmaceutical – Ensuring consistent pressure readings in sterile, high-temperature environments.

• Chemical processing – Handling aggressive or crystallising fluids without compromise.

• Energy and power – Monitoring pressure in boilers, turbines, and heat-intensive systems.

• Oil and gas – Performing in high-temperature drilling and refining environments.

Wherever extreme temperatures and challenging process conditions are present, the PR3860 delivers dependable performance.
