Overview
The MPS4000 series miniature pressure scanners have been designed from the ground up to be a ‘game changer’ in the world of multi-channel miniature pressure measurement. The MPS4164 scanner is built around a brand new ultra-stable pressure sensor. Scanivalve has worked directly with a leading pressure sensor manufacturer to develop a custom packaging solution that allows us to maximize the transducer’s stability and accuracy.

One of the significant improvements over the legacy miniature pressure scanners is the new, maintenance free valve design. The valve can be ordered in different configurations; “Normal” (NPx) and “Standard” (CPx). The normal (NPx) version of the valve defaults to the measurement mode and eliminates the need for any control pressure source except when changing the module state into Calibration / Purge mode. This can greatly simplify the system architecture and eliminate the need for multiple valves and a constant source of ‘muscle’ pressure. The alternate configuration, standard or CPx, was designed to allow the MPS scanner to be incorporated into an analog architecture. This allows the MPS modules to be installed alongside legacy products which require control pressure to switch the module into Measurement, and another control pressure to switch the module into Calibration / Purge mode.

Applications

The MPS4164 is a versatile scanner, designed for a wide range of applications. It was specifically designed for use in wind tunnel and flight test applications where operational conditions are very space constrained and pressures to do not exceed 50psi. It is also ideal for use in small supersonic wind tunnel models, where the scanner can be installed in the model or test article. This allows the tubing lengths from the testing ports to the module to be as short as possible. The simple operation, analog connectivity, and low overhead requirements also make it ideal for educational facilities, small research and development projects, automotive testing, and other quick tests with large channel counts. Also available for the MPS is a Thermal Control Unit (TCU) designed to protect the MPS in harsh environments and provide temperature control when the module may be subjected to extreme temperatures.

The MPS4164 can be used in applications such as:

    • Low pressure wind tunnel studies
    • Boundary layer measurements
    • Automotive aerodynamic studies (wind tunnel or on-car)
    • Wind and building engineering
    • Flight performance and testing
    • Educational and research facilities
    • And many more
