Pressure Modules
Pressure Modules
Pressure modules are interchangeable plug-in sensor units used with compatible pressure calibrators and process meters to extend their measurement capabilities across gauge, absolute, differential, and compound pressure ranges. By swapping modules, a single calibrator can cover a wide span of pressure measurements — from very low pressures in water column units to high pressures in bar or psi. This modularity reduces the total cost of ownership for calibration laboratories and field service teams that must service instruments across diverse process conditions.
The Druck IDOS (Intelligent Digital Output Sensor) platform is the dominant standard in this category, offering a broad family of interchangeable smart pressure modules that communicate digitally with DPI-series calibrators. Each module stores its own calibration data internally, enabling automatic range identification and ensuring traceable measurements. Pressure modules are an essential component in multi-range calibration systems used in process industries, aerospace, and metrology laboratories.
Typical Applications
- Extending the pressure range of portable calibrators for on-site transmitter calibration
- Multi-range calibration setups in metrology labs requiring gauge, absolute, and differential measurements
- Calibration of pressure transmitters in oil & gas, chemical, and water treatment processes
- Aerospace and defense testing where multiple pressure ranges are required in a single deployment
- Automated pressure calibration rigs where modules are selected programmatically by a test controller
Popular Brands
Druck (Baker Hughes) dominates this category with the IDOS/IUPM module family, offering hundreds of range variants compatible with DPI615, DPI620, and DPI705 series calibrators. Other manufacturers providing modular pressure sensor platforms include Mensor and Additel, both targeting high-accuracy calibration applications.
