Compliments PSI's Line of Pressure Scanners

Pressure Systems' DTC Initium provides a powerful yet economical data acquisition system for PSI's DTC series of miniature ESP pressure scanners. This advanced system epitomizes PSI's ambition to eliminate in-situ calibration from electronic pressure scanning technology. The DTC Initium system integrates an advanced analog circuit design with PSI's innovative Digital Temperature Compensation (DTC) technology to maintain optimal accuracy without online span calibration. The proprietary technology utilizes a unique sensor mounting technique to enable accurate measurement of bridge resistance for use in real-time correction of thermal errors using personalized compensation algorithms embedded within the scanners. The result is an electronic pressure scanning system that provides stateof- the-art accuracy over the entire scanner operating temperature after only an initial rezero.

The Ethernet-based system directly connects any combination of up to eight 32 or 64 port DTC scanners to facilitate as many as 512 channels of pressure measurements. Multiple systems can be networked for larger channel requirements. The DTC Initium supports software and hardware triggering of data sets, data packet ID stamping for time correlation, and data throughput to the host computer at rates as high as 1200 Hz per channel in engineering units. The system also supports other sophisticated DTC scanner features including programmable deranging capability and internal manifold position sensing. The system operates from a single 18-36 VDC unregulated supply.
