Fuji Electric, Data recorders PHE series

The microjet recorder is a revolutionary recorder, its ink jet color printer technology is adopted in industrial type recorders for the first time in the world. Fuji established ink jet technology based on the unique silicon chip manufacturing process for FCX transmitters. The ink jet printing mechanism provides up to 24 continuous traces with a 180mm width recorder and 6 continuous trace with a 100mm width recorder without pen offset. The mechanism also provides six sharply defined colors. Microjet recorder was designed with a reduced number of complicated mechanical parts to make it as trouble-free as possible.

The ink jet head is formed on a stable quality silicon chip. The ink jet head printing mechanism does not touch the chart paper, allowing reliable recording.

The ink jet mechanism is formed on a thin silicon chip (17.6 x 16mm) using silicon micro machining technology. It is provided with piezo elements. With voltage applied to the piezo elements, the shape of the elements changes as shown in the diagram, and ink particles are ejected from the tip of the nozzle. These particles are very small and fast, and draw a series of very small dots of about 0.3mm diameter on the chart paper. These small dots are combined together to form characters and trace lines for clear visible recording.

This recorder can record up to 6 channels of thermocouples, resistance bulbs and DC voltage/current signals. The adoption of ink jet system makes it possible to record measured data in analog trace and digital color printing (6 colors, max) on a 100mm wide chart paper.
