The DTC Initium provides a powerful yet economical data acquisition system for the DTC series of miniature ESP pressure scanners. This advanced system epitomizes MEAS ambition to eliminate in-situ calibration from electronic pressure scanning technology. The DTC Initium system integrates an advanced analog circuit design with our innovative Digital Temperature Compensation (DTC) technology to maintain optimal accuracy without on-line 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 state-of-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.

Windows® based utility software written in Visual Basic is supplied with the DTC Initium system allowing the user to configure acquisition parameters such as sample rates, averaging, and thermal update rates. It also provides diagnostic tools such as accuracy, channel crosstalk, and leak check routines. The utility software also facilitates firmware upgrades downloaded to the system via Ethernet, which are made available at no charge on our website.
