Leak Test
The leak test applies a test pressure to an external system connected to the measuring device to determine the extent of pressure changes caused by leaks. In this application, the test pressure is defined along with a hold time to minimize possible adiabatic effects during the test. Upon completion, the display shows the start pressure, end pressure, pressure difference, and leak rate.
Burst Pressure Test
The burst pressure test is an application of the PACE series, primarily designed for testing burst discs. In this process, the pressure is increased in a controlled manner to precisely determine the point at which the test object fails or bursts.

Why TERPS Sensors Are More Accurate
The accuracy of a pressure regulator or pressure controller is largely determined by the quality of the pressure sensor used. The PACE5000E and PACE6000E pressure controllers can be equipped with various CM and CM3 control modules. Particularly high accuracies are achieved with the optional CM3 control modules, which utilize Druck’s proprietary TERPS technology (Trench Etched Resonant Pressure Sensor).
This innovative sensor technology is considered one of the most accurate pressure measurement methods available today for industrial and metrological applications. Depending on the required pressure range, measurement uncertainty, and budget, users can select the most suitable control module for their application.
The key difference is that TERPS pressure sensors do not detect pressure changes through variations in electrical resistance. Instead, they measure changes in the resonant frequency of a micro-machined resonator. Frequencies can be measured with exceptional precision and are significantly less susceptible to electrical interference or long-term aging effects. This results in an extremely stable and highly repeatable measurement signal.
Higher Resolution Across the Entire Pressure Range
Many pressure sensors experience reduced measurement accuracy in certain parts of their operating range. TERPS sensors, by contrast, provide exceptionally high resolution throughout the entire working range. Even the smallest pressure changes can be detected reliably.
This is particularly important for calibration tasks where pressure sensors, pressure transmitters, or digital pressure gauges must be tested against very tight tolerances. The higher the resolution of the reference system, the more accurately the true measurement deviation of the device under test can be determined.
Low Hysteresis for Repeatable Results
Another advantage of TERPS technology is its extremely low hysteresis. Hysteresis refers to the difference between measurement values when approaching a pressure point from increasing or decreasing pressure directions.
In high-precision calibrations, even the smallest hysteresis effects can lead to measurable errors. The resonant sensor technology minimizes these effects to an exceptionally low level. The result is highly repeatable calibration performance regardless of the direction from which the test pressure is approached.
Improved Temperature Stability
Temperature fluctuations are among the most common factors affecting the accuracy of pressure measurements. Conventional sensors often react sensitively to changes in ambient temperature and require extensive temperature compensation.
TERPS sensors offer excellent temperature stability. As a result, measurement accuracy is maintained even under changing environmental conditions. This reduces measurement errors and improves the reliability of calibration and testing procedures.
Outstanding Long-Term Stability
A major benefit of TERPS technology is its long-term stability. Many sensor technologies are subject to drift, causing measurement values to change over time. This leads to more frequent recalibrations and higher operating costs.
TERPS sensors, however, exhibit extremely low long-term drift. This allows accuracy and measurement uncertainty to remain stable over extended periods. For calibration laboratories, this translates into lower maintenance costs and higher system availability.
Ideal for Calibration Laboratories and Reference Measurements
The combination of high resolution, low hysteresis, excellent temperature stability, and minimal long-term drift makes TERPS sensors the ideal foundation for high-precision pressure controllers such as the PACE5000E. This is why they are used worldwide in calibration laboratories, research institutes, production test facilities, and demanding reference measurement applications.
For users, this means greater measurement confidence, lower measurement uncertainties, and reduced operating costs over the long term. For these reasons, TERPS technology is widely regarded as one of the most advanced pressure measurement technologies available for industrial calibration and testing applications.
Frequently Asked Questions About the PACE5000E
What is the difference between a pressure regulator and a pressure controller?
The terms pressure regulator and pressure controller are often used interchangeably. In practice, a pressure regulator generally refers to a device used to set and stabilize pressure. A pressure controller usually refers to an electronically controlled precision instrument capable of automatically generating pressure setpoints, maintaining stable pressures, and integrating into test or calibration systems via communication interfaces. The PACE5000E is therefore a high-precision electronic pressure controller and regulator designed for calibration and testing applications.
Which pressure media can be used?
The PACE5000E is designed for clean, dry, non-corrosive, and non-flammable gases. Typical pressure media include dry air and nitrogen. Liquids, contaminated media, aggressive gases, or flammable gases are not suitable for direct operation.
Can the PACE5000E be used as a reference standard?
Yes. When combined with suitable PACE CM or CM3 control modules, the PACE5000E can be used as a highly accurate reference pressure controller. It is well suited for calibration laboratories, factory calibrations, test benches, and automated pressure calibration systems that require stable and traceable reference pressures.
What are the advantages of TERPS technology?
TERPS stands for Trench Etched Resonant Pressure Sensor. This technology provides extremely high resolution, low hysteresis, excellent repeatability, and outstanding long-term stability. These characteristics enable highly accurate pressure measurements with very low measurement uncertainty.
Which communication interfaces are supported by the PACE5000E?
Depending on the configuration, the PACE5000E supports various communication interfaces for integration into testing and calibration systems. These typically include Ethernet/LAN, USB, RS232, and optional IEEE-488/GPIB. This allows the instrument to be operated both manually and within fully automated systems.
How does the automatic pressure control function work?
In automatic pressure control mode, the user enters a desired pressure setpoint. The PACE5000E continuously compares this target value with the measured actual pressure and automatically adjusts internal control valves as required. This allows the desired pressure to be reached quickly, maintained with excellent stability, and reproduced consistently for calibration and testing procedures.
