HI2000 High Precision Pressure Transducer

The HI2000 Series High Precision Pressure Transducer is designed to deliver accurate, stable, and reliable pressure measurement across a wide range of industrial and test applications. Built around advanced Silicon-on-Sapphire (SoS) sensing technology, the HI2000 offers exceptional long-term stability, minimal hysteresis, and excellent thermal performance.

Engineered for use in demanding environments, this high-performance pressure transducer combines precision measurement with rugged construction, making it suitable for aerospace, laboratory testing, oil and gas monitoring, and subsea applications.

Advanced Silicon-on-Sapphire Sensor Technology

At the core of the HI2000 is Silicon-on-Sapphire (SoS) sensing technology, a proven solution for achieving high accuracy and stability in pressure measurement applications.

The sensor is constructed using a piezoresistive silicon strain gauge circuit that is epitaxially grown onto a sapphire diaphragm, forming a single crystalline structure. This sapphire element is then molecularly bonded to a titanium alloy sub-diaphragm, resulting in a robust and highly stable sensing assembly.

This advanced design provides several key performance advantages:

• Virtually no hysteresis

• Outstanding long-term measurement stability

• High resistance to overpressure conditions

• Excellent insulation properties

These characteristics enable the HI2000 to maintain consistent and reliable output even in demanding operating environments.

High Accuracy and Repeatability

The HI2000 Series is designed to provide precise pressure measurement with an accuracy of ≤ ±0.1% of span (BFSL). This level of performance ensures that the sensor can be used in applications where measurement precision is critical.

With a fast response time of approximately 1 millisecond, the HI2000 is capable of capturing rapid pressure changes, making it suitable for dynamic measurement applications such as engine testing, hydraulic systems, and process monitoring.

Wide Pressure Range Capability

The HI2000 is available in a broad range of pressure options, allowing it to support both low-pressure and high-pressure applications:

• From vacuum and low-pressure ranges

• Up to 1,500 bar (20,000 psi)

This wide range makes the HI2000 a versatile solution for industries requiring accurate pressure measurement across varying operating conditions.

Flexible Output Signal Options

To accommodate different system requirements, the HI2000 Series offers multiple output configurations:

• 10 mV/V (4-wire configuration)

• 0–5 V output

• 0–10 V output

These options allow for seamless integration into a wide variety of data acquisition systems, control systems, and instrumentation setups.

The amplified voltage output versions also include protection against supply voltage reversal, adding an extra layer of reliability in industrial installations.

Excellent Thermal Stability

The HI2000 is designed to maintain stable performance across a wide temperature range. Its Silicon-on-Sapphire construction allows the sensor to operate without significant drift, even when exposed to varying thermal conditions.

Key temperature characteristics include:

• Operating ambient temperature: -40°C to +85°C

• Operating media temperature: -50°C to +125°C

• Low thermal coefficients for zero and span

This ensures that measurement accuracy is maintained across changing environmental conditions, reducing the need for frequent recalibration.

Rugged Construction and Chemical Compatibility

The HI2000 features titanium alloy wetted parts, providing excellent compatibility with a wide range of pressure media.

Benefits of this construction include:

• High resistance to corrosion

• Compatibility with aggressive fluids

• Long service life in harsh environments

These properties make the HI2000 well suited for applications in oil and gas, chemical processing, and subsea systems where durability is critical.

High Overpressure Capability

The HI2000 is engineered to withstand overpressure conditions, helping protect the sensor from damage during pressure spikes:

• Up to 4× overpressure for low ranges

• 2× for mid-range pressures

• 1.5× for higher ranges

• 1.1× for maximum range

This robust overpressure capability enhances reliability in dynamic systems and helps extend the operational life of the sensor.

Optional ATEX and IECEx Certification

For applications in hazardous environments, the HI2000 Series is available with optional ATEX and IECEx certification.

These approvals make the sensor suitable for use in:

• Explosive gas environments (Zone 0)

• Dust environments (Zone 20)

• Mining applications (Group I M1)

This allows the HI2000 to be deployed safely in industries where explosion protection is required.

TEDS Capability for Smart Sensor Integration

The HI2000 is available with optional Transducer Electronic Data Sheet (TEDS) functionality, compliant with IEEE 1451.4 standards.

TEDS technology allows the sensor to store critical calibration and identification data, enabling:

• Automatic sensor recognition

• Simplified system setup

• Reduced configuration errors

This feature is particularly useful in advanced measurement systems and automated test environments.
