ExM – External Pressure Module

ExM – External Pressure Module

Overview:
The ExM External Pressure Modules are high-accuracy pressure measurement accessories designed to expand the capability and flexibility of multifunction calibrators used in industrial calibration applications. With an impressive accuracy of 0.025% of full scale and pressure ranges covering vacuum up to 1000 bar, these modules enable technicians to perform precise pressure calibration across a wide variety of pneumatic and hydraulic ranges. The modules support gauge measurements and provide 14 selectable pressure units, allowing convenient operation across different industry standards and testing requirements.

Built with a plug-and-play design, the ExM modules can be easily connected to compatible calibrators, allowing users to switch between pressure ranges without needing multiple standalone instruments. The robust ABS casing and SS316-compatible pressure media design ensure reliable performance with both gases and non-corrosive liquids. Compact, lightweight, and easy to carry, these modules provide a practical and flexible solution for laboratories and field technicians who require accurate pressure calibration across multiple ranges while maintaining a single centralized calibration system.

  • Accurate vacuum and high-pressure measurement in pneumatic and hydraulic calibration systems.
    Expansion of multifunction calibrator capabilities by enabling calibration of different pressure ranges using interchangeable modules.
  • Used in calibration laboratories for high-precision pressure measurement and traceable calibration activities.
  • Field calibration and maintenance of process instrumentation in industries such as oil & gas, power generation, petrochemical, and manufacturing.
  • Testing and validation of industrial pressure sensors and transducers during commissioning and preventive maintenance.
  • Monitoring and verification of process pressure systems requiring high accuracy and multiple pressure units.
    Supporting quality control and instrumentation servicing where flexible pressure measurement ranges are required.
