Ethernet Model 9021

Pressure Systems, Inc. has introduced the Ethernet Model 9021, a turnkey all-media pressure acquisition module that can support up to 12 discrete all-media pressure transducers and utilizes a 10 BaseT Ethernet interface using TCP/IP protocol. In addition, DC voltage signals can be measured on any unused input channel.

The product uses an internal 32-bit microprocessor to correct for pressure transducer zero, span and nonlinearity errors. It performs digital temperature compensation of the sensors to reduce thermal errors by a factor of ten or more over conventional sensor compensations. The microprocessor also controls an off-line rezero or even span calibration to maintain long term sensor accuracy.

The new module offers pressure ranges from 0-5 psi to 0-10,000 psi (35 kPa to 69 Mpa) gage or absolute; other ranges are available upon request. It features measurement resolution of ±0.003% full scale, and pressure system accuracy of up to ±0.10% full scale.
