RMS INSTRUMENTS has developed a variety of chart recorders and graphic printers using advanced thermal array technology. Based on sophisticated multi-processor architectures and firmware, these instruments can operate in stand-alone mode accepting signals directly from sensors, as peripheral devices under control of a computer or data acquisition system, or in a mode that combines the functionality of the two above.
In thermal printing, energy in the form of heat is transferred from miniature heating elements organized in an array along a printhead to the thermal recording medium. Through carefully designed, proprietary firmware and hardware techniques, the system controls the energy applied to print elements and the timing of numerous signals that result in the printing of sharp graphic images, traces, text, and other forms of annotation – all over a wide range of print speeds, resolutions as high as 11.8 x 11.8 dots/mm (300 dpi), and on 321-mm wide print media. By continuously adjusting print variables based on measurements of printhead temperature and print rates, outstanding photographic quality is achieved in images printed using the gray scaling capability of some models – true gray scaling with 16 shades, in which the gray shade of each print element is individually modulated by the image data. Superior-quality thermal media (paper and film) supplied by RMS INSTRUMENTS ensures outstanding print quality and longevity.
Application Note: RMS2030 Thermal Papers 
Printing based on RMS INSTRUMENTS' thermal array technology is ideal for harsh environments in which instrumentation is exposed to wide temperature ranges and vibration. Minimal maintenance and support are required. Totally eliminated are the complicated mechanisms for pen positioning and control, and the ensuing high maintenance cost, the need for replacement cartridges/ribbons, and the frequent problems such as smearing of ink and nozzle clogging associated with other technologies.
