These BA304E & BA324E fourth generation intrinsically safe 4/20mA loop powered indicators have large high contrast displays with a very wide viewing angle. Operating over an extended temperature range they contain many standard features previously only available as options. Coated printed circuit boards plus extensive thermal and vibration testing provides maximum reliability supported by a three year guarantee.
No additional charge is made for factory calibration or for escutcheon scale and tag marking, however the indicators can easily be recalibrated on-site.
Other loop powered indicators in this range include:
