    The Precision Digital ProtEX-Pro PD6800 is one of Precision Digital’s most advanced and feature-packed explosion-proof yet loop-powered indicators. The PD6800 meter is loop-powered, meaning there is no need to plug the more expensive power supply into hazardous areas. Like all Precision Digital ProtEX products, the PD6800 carries ATEX, CSA, IECEx, and FM approvals for applications in hazardous areas. The PD6800 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 while a seven alpha-numeric character lowers display and is available with a twenty-segment bar graph for level applications. Two main features that 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 and operate in a hazardous area.

    Application

    Input Signal Conditioning

    Live Input Calibration

    In place of meter scaling, the meter can be calibrated with a precision signal calibrator. While applying a precision signal, the relative scale value is entered via the front panel. This is done at any two points along the scale. Using this method, the operator can set a “best fit straight line” for non-linear input spans.

    Multi-Point Linearization

    Up to 32 points linearization can be selected under the Linear function. The multi-point linearization can be used to linearize the display for non-linear signals such as those from level transmitters used to measure volume in odd-shaped tanks or to convert level to flow using weirs and flumes that require a complex exponent. These points are established via direct entry (SCALE) or with an external calibration signal (CAL).

    Square Root Extraction

    The square root extraction function displays the flow rate by extracting the square root from a differential pressure transmitter signal. The user-selectable low-flow cutoff feature gives a reading of zero when the flow rate drops below a user-selectable value.

    Programmable Exponent

    The programmable exponent function is used to linearize the level signal in open channel flow applications using weirs and flumes and display flow rate and units of measure.
