Pressure Measurement Products

Intelligent Pressure Scanners

The DSA (Digital Sensor Array) Pressure modules are all intelligent. They contain 16 temperature
compensated piezoresistive pressure sensors, 16 bit A/D converter, and a microprocessor. These
compact self contained modules communicate Ethernet TCP/IP. Pressure data are output in one of
24 Engineering Units. Optional LabVIEW drivers and OPC server are available. Features include:

+/- .05% full scale long term accuracy
500Hz/channel/second sampling speed
Multiple pressure ranges available per DSA
Vacuum, 10 inch H20 up to 1000 psi pressure range
Auto zero offset correction

Miniature Pressure Scanners

The line of ZOC (Zero, Operate, and Calibrate) Electronic Pressure Scanners incorporates a pressure sensor per channel. These sensors are piezoresistive differential sensors. Also included is a high speed multiplexer, amplifier, ID chip, RTD, and auto calibration valving. Full scale output is 0-2.5 Vdc (std) or 0-5 Vdc (optional). These scanners are designed to be used with the users’ in-house data systems, RAD remote A/D, or DSM Digital Service Module. Features include:

8, 16, 32, 64 and 128 pressure inputs
20kHz up to 100 kHz sampling speed
10 inch H20 up to 750 psid full scale pressure ranges
Transducer per channel
