Hazardous Area

Hazardous Area
Precision Digital manufactures a wide range of rugged meters and controllers designed for quick and easy display of a variety of process signals in harsh or hazardous areas. These signals include 4-20 mA, 0-10 V, strain gauge, pulse, thermocouple and RTD. Our hazardous-area instruments are approved by FM, CSA, ATEX, and IECEx as explosion-proof, intrinsically safe, and nonincendive. Many of our explosion-proof models feature SafeTouch® through-glass buttons which ensure safe operation without the need to remove the cover. Intrinsically safe, loop-powered instruments derive their operating power from the 4-20 mA current loop with a relatively low voltage drop, preventing the need to run additional, costly power lines into the hazardous area.

  • The ProtEX-Pro PD6800 is one of Precision Digital's most advanced and feature-packed explosion-proof, loop-powered indicators. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. Like all ProtEX products, the PD6800 carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. It features a dual-line display that can be easily scaled in the field for any 4-20 mA analog input. The display has a five digit upper display, a seven alpha-numeric character lower display, and is available with a twenty-segment bar graph for level applications. Two features that really make the PD6800 stand out are its wide viewing angle display and SafeTouch® through-glass buttons. These buttons allow the PD6800 to be programmed and operated through the glass, thus eliminating the need to remove the cover in a hazardous area.

  • The Loop Leader PD6600 is an ATEX, IECEx approved, and UL listed, intrinsically safe and nonincendive, loop-powered, 1/8 DIN process meter. A dual-line display featuring five digits on the top line and eight digits on the bottom line, preprogrammed engineering units, loop-powered backlight with a unique red backlight option for alarm conditions, and optional bargraph display (PD6608) or feet & inches display (PD6607) provide a clear and attractive presentation of the process. All models come equipped with two open collector outputs and are available with two solid state relays and a 4-20 mA analog output. These outputs can be programmed for alarm indication, signal retransmission via pulse or analog signal, pump control, and a number of other useful features. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines; the meter gets all of the power it needs from the 4-20 mA loop. The Loop Leader loop-powered process meter is built in a shallow-depth case with a IP65 front and features loop-powered backlighting and a wide -40 to 158°F (-40 to 70°C) operating temperature range. It doesn't matter if it's hazardous areas, indoors or outdoors, in bright sunlight or a dimly lit plant, or in an area that is wet, dirty, hot, or cold, the Loop Leader can go just about anywhere.

    Why you should buy:
  • The Loop Leader+ loop-powered large display meters
    can be installed virtually anywhere to provide convenient
    and informative display of any 4-20 mA signal. One of
    the most convenient features of these instruments is their
    large, dual line display. The 2.8" 5-digit top display is used
    to display the process variable while the 1.5" 8-character
    alphanumeric bottom display can be used to display the
    units of measure or a tag. Feet and inches models display
    level in feet and inches on the top display while the 8-digit
    alphanumeric bottom line may be used to display a tag or
    custom message.

    Further enhancing the display on these instruments is a
    20-segment bargraph that also includes a numeric value of
    the percentage the bargraph represents.
    Free, PC-based, MeterView XL software that connects
    to the meter via a micro USB cable is available for
    programming and setup of the meters.

    The PD4 is available in two configurations: Display only
    and with two solid-state relays and 4-20 mA analog output.
    All models come equipped with two open collector outputs
    and remote contacts. The open collector outputs are
    useful for alarm indication. The remote contacts can be
    used to remotely operate the four programming buttons, to
    acknowledge the relays, to start/stop a timer/stopwatch, and
    more. The relays can be programmed for alarm indication,
    on/off control, or pump alternation.
