Panel meters show
their true-blue colours
Datel's top selling DMS-20PC series of subminiature 3.5-digit DPMs are now offered with brilliant blue LED displays
The unique, eye-catching qualities of the colour blue are finally suitable for medical, marine, and industrial applications. Thanks to state of the art, 470nm, InGaN (indium gallium nitride) blue LED technology, designers now have an affordable and reliable alternative to expensive, vacuum-florescent displays.

SNR is key spec for speedy sampling convertor
The ADS-953 sampling ADC optimises signal return paths and provides internal, local decoupling to obtain an outstanding -95dB peak harmonic specification and 76uV RMS noise-level performance
Applications requiring two or more display colours can now take advantage of the most sought after LED colour - radiant, true blue.
All DMS-20PC-BS digital display meters are housed in a blue, epoxy-encapsulated, 12-pin, DIL-style plastic package that, when mounted in panels, has a 35 x 22mm footprint.
Nevertheless, display size and readability are not compromised in any way as the small package houses a large 9.2mm-high 3.5-digit display easily viewable from as far as 15ft.

The 12-pin DIL package's unique design features a built-in high-contrast blue filter, enabling these subminiature DPMs to be used in stand-alone, PCB mount applications - no additional bezels, filters, or polarisers are required.
Best of all, the entire assembly occupies only 6.5cm2 of valuable PCB space.
Until now, blue LEDs have been expensive, notoriously power hungry and disappointingly dim.
These three drawbacks all but ruled out their use in the vast majority of instrumentation applications.
Datel's new DMS-20PC-BS series digital voltmeters rewrite all the rules.
Their brilliant, 470nm wavelength (the truest blue) LED displays are visible in the brightest ambient lighting, but draw less than 0.5W (85mA) from a single +5V supply - that's actually less than most standard red LED displays.
DMS-20PC-BS series meters combine precision bandgap voltage references and metal-film resistors to achieve unprecedented accuracy and stability at all input levels.
An automatic zeroing circuit ensures a 0V input.
Four differential, high-impedance input ranges are available: +/-200mV, +/-2V, +/-20V and +/-200V.
Factory calibration achieves an impressive +/-2 counts (0.1%) long-term accuracy.
And for added versatility, a display enable input provides designers high-resolution control over the displays intensity.
Datel now accepts credit card orders for digital panel meters at its website.
