64-CHANNEL MODULAR PRESSURE SCANNER SYSTEM
Low-cost, multi-channel pressure measurement
This low-cost, high-functionality pressure indexing system is an ideal solution for any multichannel pressure measurement requirements. With self-detecting, hot-swappable modular transducer cards and ranges down to +/- 160 Pa full-scale, this system offers maximum flexibility for rapidly changing requirements.
Whether for surface pressure measurements, multi-hole velocity probes or process control applications, this system provides a high-sensitivity, highly adaptable solution for all your pressure measurement needs. Pressure sensors are mounted in banks of eight on interchangable cards, each carrying its own on-board memory factory-loaded with calibration data. The system includes full local environment sensors for temperature, density and humidity corrections, as well as a remote fluid temperature sensor. The system is available in a variety of enclosures, or as an OEM unit.
Applications
Multichannel pressure measurement
Wind-tunnel testing
Rapid, quasi-simultaneous sampling of up to 64 pressure channels for model surface pressure characterization, lift/drag estimates and facility pressure gradient monitoring
Multi-hole velocity & vorticity probes
With modular banks of eight channels, full-scale pressure ranges down to 160 Pa and an additional remote fluid temperature sensor, this system is ideal for driving arrays of seven-hole probes, n-hole vorticity probes and probe rakes.
Process control
As an OEM unit, this system can be easily integrated into process control systems, gas distribution and regulation systems, or HVAC controllers. Its robust, modular construction allows easy installation and maintance, while its low power requirements and simple USB interface requires minimal system resource.

Firmware update utilities
Firmware update to v2
This utility will update version 1.x firmware builds (factory-installed on scanners produced between 1 April 2014 and 31 December 2022) to version 2, compatible with software releases up to version 2.1. Note that firmware versions 1 and 2 are not inter-compatible. This update is recommended for ‘clean rebuilds’ only.
Firmware recovery utility:
This utility will restore a version 2 firmware to version 1.4, and enable legacy software and LabView VIs to be used. Note that version 1.x is deprecated.
Software version 1.4
Provided for scanners produced from 1 April 2014 to 31 December 2022. Software version 1.x is no longer supported.
