Pressure Measurement Snap-in_TI_resized

Pressure Measurement Snap-in

This snap-in unit provides exact acquisition of 12 independent pressure signals in the field of automotive engine and powertrain testing.

AVL Approach

The signals acquired by each pressure transducer are transferred in physical units to the AVL PUMA OpenTM automation system by means of a CANopen interface. The snap-in unit is designed for installation in the AVL Measurement Box.

The miniature CANopen pressure transducers are mounted in the 12-channel Pressure Measurement Snap-in. The snap-in unit can house transducers with relative or absolute pressure measurement ranges.

Typical applications are R&D and Emissions and Quality Assurance testbeds equipped with AVL´s Measurement Box.


Benefits at a Glance

  • Exact acquisition of dynamic pressure signals due to data acquisition rates of up to 200 Hz per channel
  • Real-time data synchronization with the AVL PUMA OpenTM testbed automation system
  • Automatic sensor detection (measuring range, serial number, type)
  • Zero offset adjustment directly in the pressure transducer controlled by AVL PUMA OpenTM
  • Vibration resistant for usage on engine pallets
  • Fast and convenient installation in the AVL Measurement Box with automatic connection to power supply and data bus for fast setup
