The
DSA3016 Digital Sensor Array is ideal for measuring pressures
on turbomachinery, turbine engines, compressors, and other
industrial applications where ambient temperatures vary. The DSA
temperature compensated pressure sensors are more than ten times
less sensitive to temperature than typical piezoresistive pressure
sensors. Up to 8
DSA3016 pressure modules (16Px) are supported by a DSAENCL4000
enclosure (128Px inputs).
DSA3016 modules have a front panel power cutoff switch that
allows them to be "Hot Swappable" without having to power down the
system. They also have an illuminated power switch that blinks when
scanning. The DSAENCL4000 enclosure has an Ethernet link and
activity LED on the front.
DSA3016 pressure modules will work with all DSAENCL3000, 3200,
and 4000 series enclosures.
Model
DSA3016, Digital Sensor Array, is a rack mounted module
designed for multiple pressure measurements. Each
DSA3016 module 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 8
DSA3016 Digital Sensor Array modules can be used in a 19 inch
rack enclosure, Model DSAENCL4000. 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 measurements are converted into Engineering
Units.
The DSP processor also controls the actuation of an internal
calibration valve to perform on-line zero calibrations. Long term
system accuracy is achieved for up to 6 months. All
DSA3016 modules manufactured after first quarter 2004 have an
ID chip installed. The DSAENCL4000 DSP processor reads the serial
number, pressure range, etc. of each
DSA3016 module and its location in the enclosure from the DSA
module ID chip.
Included with the DSAENCL4000 is a micro SD card. It can
be used for data storage and is easily removed for security
reasons. The enclosure utilizes a pressure temperature look-up
table to compensate the pressure sensors for temperature changes,
thereby reducing thermal errors.
