Paroscientific 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.  Direct digital 
outputs in engineering units are provided with parts-per
billion resolution using the built-in, anti-aliasing IIR filter 
mode. Typical accuracy is 0.01% even under harsh 
environmental conditions. All intelligent transmitters are 
preprogrammed with calibration coefficients for full plug-in 
interchangeability. 
 
Intelligent transmitters are available in 20 absolute pressure 
ranges from 15 psia (0.10 MPa) to 40,000 psia (276 MPa), 
and 7 gauge pressure ranges from ± 2 psig (±0.015 MPa) to 
200 psig (0.15 MPa). 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. 
 
Features include support for both serial loop and multi-drop 
networking, high-speed continuous pressure measurements, 
selectable baud rates up to 115,200 baud, synchronization of 
measurements with time-based integration, 2 or 4 wire RS
485 transmission distances greater than 1 kilometer, 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. 
 
All Digiquartz® Transducers come with a limited 5-year 
warranty with the first 2 years covered at 100%.
