Overview

The DSA3016 , or Digital Sensor Array, is a 16 channel analog pressure scanner designed to be mounted in the DSAENCL4000, 19″ Rack mount enclosure. Each DSA3016 modules incorporates 16 temperature compensated piezoresistive pressure sensors, along with a pneumatic calibration valve. Field replaceable sensors assure that downtime is minimized in the unlikely event of sensor damage. Up to 8x DSA3016 modules can be used in a single 19 inch rack enclosure. Each installed DSA module can be a different pressure range or pneumatic configuration, such as true differential or common differential modules. Long term system accuracy of the DSA’s pressure sensors is achieved for up to 6 months, and can be calibrated and validated in the field to maintain accuracies.

The DSAENCL4000 pressure acquisition system represents the next generation of intelligent electronic pressure scanning. The state-of-the-art DSP technology is at the heart of our new 19 inch rack mounted DSAENCL4000 enclosure. Located on the backplane of the enclosure, the Digital Signal Processor (DSP) is a programmable device capable of extremely fast math functions that operate on the data stream in real time. All pressure measurements sensed at each channel of the installed DSA3016 modules are converted into Engineering Units, which are output using TCP, UDP or FTP protocol over the Ethernet connection. The DSP processor also controls the actuation of the DSA’s internal calibration valve to perform online zero calibrations or purge functions. The DSAENCL4000 will automatically read the serial number, pressure range, etc. of each installed DSA3016 module and its location in the enclosure using each DSA module ‘s unique ID chip. The enclosure utilizes a pressure temperature look-up table for each installed DSA module to compensate the pressure sensors for temperature changes, thereby reducing thermal errors. As of September of 2021, the DSAENCL4000 is IEEE1588-2008v2 Precision Time Protocol compliant for high accuracy synchronization with PTP Networks.
