The instrument is loop powered but only induces a 1V drop which allows it to be installed in series with almost any 4-20mA loop. The zero and span of the display are independantly adjustable so that the indicator can be calibrated to display any linear variable represented by a 4-20mA signal, such as temperature, pressure, level or actuator position.

For flow applications the BA304 can be provided with an optional square root extractor which enables the output from a differential flow transmitter to be displayed in linear engineering units. Backlighting is also available as an option for use when the ambient lighting is poor. The BA304 comes in a choice of GRP or aluminium field housings.
