    Process Indicator

    The DI2WP Loop Powered process Indicator is a self powered 4-20mA input surface mounting process indicator which is housed in a 140 x 80 x 65mm impact resistant weatherproof plastic enclosure. The instrument incorporates a 3.5 digit 25mm high LCD display with a wide viewing angle. It is user programmable in engineering units.

    • Accepts 4-20mA or 10-50mA input
    • User programmable in engineering units
    • Loop powered
    • Low cost - High Performance
    • Positive or negative signal slope selection
    • DI2WP is in a weatherproof enclosure
    • Applications include the display of flow, level and pressure
    • Australian design and manufacture

    The DI2WP instrument has been designed to accept an input signal of 4-20nA or 10-50mA and be powered from that signal. The input measurement is shown on a 25mm digit height 3.5 digit liquid crystal display (LCD).

    They are user programmable in percent or engineering units for such process variables as flow, level, pressure and temperature.

    The instruments have been designed to reject electrical interference that normally abounds in industrial environments.

    The DI2WP is supplied in an IP65 rated surface mount weatherproof enclosure.
