It is available with either gauge reference or bi-directional measurement, providing flexibility for different installation requirements.

Advanced Silicon-on-Sapphire (SoS) Sensor Technology

At the heart of the PR3200 is ESI Technology’s proven Silicon-on-Sapphire (SoS) sensor technology.

Unlike conventional pressure sensing technologies, SoS sensors combine a silicon strain gauge with a sapphire substrate. This unique design provides exceptional mechanical strength, excellent long-term stability and outstanding resistance to corrosion.

The result is a pressure transmitter that offers:

• Excellent long-term measurement stability
• Outstanding resistance to overpressure
• Minimal hysteresis
• High accuracy across a wide operating temperature range
• Reliable performance in harsh industrial environments

These benefits help reduce maintenance requirements while providing dependable measurements throughout the product’s service life.

Designed for Hazardous Areas

Many industrial processes operate in potentially explosive atmospheres where safety is critical.

For these environments, the PR3200 is available with an optional ATEX and IECEx certified intrinsically safe version. This allows the transmitter to be installed safely in hazardous gas and dust zones, making it suitable for applications within the chemical, oil and gas, hydrogen, energy and process industries.

Choosing an intrinsically safe differential pressure transmitter helps engineers meet safety requirements without compromising measurement performance.

Typical Applications for the PR3200

The versatility of the PR3200 makes it suitable for a wide range of industrial applications.

Flow Measurement

Differential pressure is one of the most widely used methods for measuring flow. The PR3200 works alongside orifice plates, venturi tubes and mass flow meters to provide accurate flow measurement for liquids and gases.

Filter Condition Monitoring

As filters become blocked, the pressure difference across them increases. By continuously monitoring differential pressure, the PR3200 helps identify when filters require maintenance or replacement, reducing downtime and improving system efficiency.

Hydraulic Systems

High-pressure hydraulic equipment depends on accurate pressure monitoring to ensure safe operation. The PR3200 provides reliable differential pressure measurement in demanding hydraulic applications.

Combustion Control

Maintaining the correct pressure balance within combustion systems helps improve efficiency and supports safe operation. The PR3200 provides accurate measurements that assist with process control.

Process Monitoring

Many industrial processes require continuous monitoring of pressure differences between tanks, pipelines or vessels. The PR3200 delivers stable, repeatable measurements for reliable process control across a wide range of industries.

Built for Long-Term Reliability

Industrial environments demand equipment that can withstand challenging operating conditions.

The PR3200 features titanium alloy sensing elements and stainless steel wetted parts, providing excellent corrosion resistance and durability. User-accessible zero and span adjustments also make on-site calibration straightforward, helping reduce maintenance time and simplifying commissioning.

Combined with ESI Technology’s proven sensor design, the PR3200 provides dependable performance even in applications where pressure fluctuations and demanding operating conditions are common.
