The HBS307E is a loop-powered 4 digit lcd indicator
used to display a measured variable in customer
selected engineering units within a hazardous area.
The zero and span of the display are independently
adjustable allowing the indicator to be calibrated to
display any linear variable represented by the 4 to
20mA signal. The scale card can easily be marked
to show the units of measurement and be installed
on-site without dismantling the indicator enclosure or
removing it from the panel.
A bold 15mm high 4 digit display provides maximum
contrast and has a very wide viewing angle, allowing
the indicator to be read easily in most lighting
conditions over a wide temperature range. The four
digits, with three decimal points and a negative sign,
may be configured to display any variable between
-9999 and 9999.
