DatasheetThe PACE CM3 is the most advanced pressure control module in Druck’s PACE series. Designed for the highest demands in pressure calibration and automated testing, it offers reference-level accuracy, outstanding long-term stability, and seamless integration with the modular PACE 5000 and PACE 6000 chassis.
Key Features
- Reference accuracy up to 0.001% of Full Scale (FS)
- Long-term stability up to 0.001% FS over 28 days
- Absolute and pseudo-gauge pressure ranges up to 211 bar (3060 psi / 21.1 MPa)
- High resolution and fast response – ideal for automated calibration and test systems
- Optional barometric reference for pseudo pressure measurements
- Modular concept – hot-swappable integration into PACE 5000/6000 chassis
- Digitally characterized for maximum repeatability and ease of re-calibration
Typical Applications
- Calibration laboratories with high accuracy requirements
- Automated test benches and OEM production lines
- Aerospace testing (including barometric altitude simulation)
- Research, development, and validation
