Features and Specifications

Typically, the RADBASE would be located inside a wind tunnel model or other space limited location in close proximity to the ZOC pressure scanners.  For small models with low number of pressure channel requirements, the RADBASE can be minimal size to fit into the model. For large systems the ERAD system can be expanded with modular A/D modules for up to 512 pressure channel system. A feature of the system is that each A/D and each ZOC pressure scanner has an ID chip installed. During power up or on demand, the RAD can read the ZOC ID chip information – model, pressure range, serial number, number of channels, date of manufacture and calibration date.

This new Ethernet remote A/D system is a turnkey pressure measurement system that combines the field proven RAD with Ethernet TCP/IP. The state-of-the-art DSP technology is at the heart of our new ERAD4000 pressure measurement system. Located inside the RADBASE is a programmable device, (Digital Signal Processor, DSP) capable of extremely fast math functions that operate on the data stream in real time. All measurements are converted into Engineering units. The ERAD system is modular and allows up to 8 each A/D (16 bit) modules to be plugged into one RADBASE.  Each A/D supports one 16, 32, or 64 channel ZOC pressure scanner or one ZOCEIMscanner. The RADBASE is small enough to fit inside many wind tunnel models.The RADBASE DSP processor utilizes a pressure temperature look-up table to compensate the pressure sensors for temperature changes, thus reducing thermal errors. Long term accuracy is achieved for up to 6 months before recalibration is required. ERAD4000 system is capable of maintaining its performance even as computer technology and operating systems upgrade. ERAD will work on any hardware platform that has an Ethernet port, minimizing the user’s future interface risks.
