These Intelligent Transmitters consist of a Digiquartz® pressure transducer and a digital interface board in an integral package. Commands and data requests are sent via two-way RS-232 or RS-485 serial interfaces. Digital outputs are provided directly in engineering units with typical accuracy of 0.01% over a wide temperature range. Output pressure is fully thermally compensated using a quartz crystal temperature signal. All intelligent transmitters are preprogrammed with calibration coefficients for full plug-in interchangeability.
Intelligent Transmitters are available in 19 absolute pressure ranges from 15 psia (0.10 MPa) to 40000 psia (276 MPa) and 6 gauge pressure ranges from 15 psig to 200 psig. Dual RS-232 and RS-485 interfaces allow complete remote configuration and control of all operating parameters, including resolution, sample rate, choice of engineering units, integration time, and sampling requests. Commands include: Single sample and send, synchronized sample and hold, continuous sample and send, and special burst sampling modes.
New and enhanced features include support for both serial loop and multi-drop networking, selectable baud rates up to 115200 baud, synchronization of measurements with time-based integration, 2 or 4 wire RS-485 transmission distances greater than 1 kilometer, improved high-speed continuous pressure measurements, a power management “sleep” mode, data formatting features, and unit identification commands.
Free software is included for setup, configuration, sampling, display, data logging, and plotting.
