The DSA3200 series pressure acquisition systems represent the next generation of multi-point electronic pressure scanning. Model DSA3207 Digital Sensor Array, incorporates 2 to 16 temperature compensated media isolated piezoresistive pressure sensors with individual bleed valves. Each DSA module also contains RAM, 16 bit A/D converter, and a microprocessor in a compact selfcontained module. The result is a network ready intelligent pressure scanning module for liquid service.
The microprocessor compensates for temperature changes and performs engineering unit conversion. Pressure data are output in engineering units via Ethernet using TCP/IP protocol.
The Model DSA3207 incorporates 2 to 16 manually activated bleed valves for venting gas from the input lines. These individual bleed valves also allow for back charging the DSA input lines. DSA firmware allows for liquid head correction and rezeroing of the pressure sensors. The pressure transducers have a long-term accuracy of ±0.12% FS (ranges 15...300 psi). Recalibration is recommended at 6 month intervals.
Applications
The DSA3207 Digital Sensor Array is designed for turbine engine and diesel engine test applications, and other liquid applications. It is ideal for industrial pressure measurement where long calibration intervals are required and temperatures can vary greatly. The DSA temperature compensated pressure sensors are more than ten times less sensitive to temperature than typical piezoresistive pressure sensors.
The materials of construction include 316 stainless steel and BUNA-N seals. Neoprene and Viton® seals are also available.
