Pressure
Precision Digital offers a wide range of digital panel meters and explosion-proof displays for use in pressure applications. Most of our meters include square root extraction and multi-point linearization signal conditioning features for non-linear pressure transmitter signals. This allows them to be used in even the most complex pressure monitoring systems. Pressure meters are available in NEMA 4X front digital panel meters and FM, CSA, ATEX, and IECEx approved explosion-proof meters for hazardous areas.

  • The Loop Leader PD688 is an Intrinsically Safe and Nonincendive, loop-powered, 1/8 DIN digital panel meter designed for hazardous process control applications. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area; the meter gets all of the power it needs from the 4-20 mA loop. The PD688 loop-powered indicator is built in a shallow-depth case with an FM Type 4X front and features loop-powered backlighting and a wide -30 to 65°C operating temperature range. It doesn't matter if it's 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. The PD688 can be installed in just about any hazardous area environment under the FM, CSA, and ATEX standards.

  • The PD662 NEMA 4X, CSA Certified loop-powered meter is perfect
    for applications where a simple, inexpensive display is required
    and AC power is not available. The PD662 derives all its power
    from the 4-20 mA loop, including its optional backlight feature. It
    can be easily scaled in the field using four push buttons; with or
    without applying an actual calibration signal. The PD662’s display
    will read up to 2999; we call this 3½+ digits! The PD662 is housed
    in a rugged NEMA 4X enclosure and is provided with one ½" NPT
    pipe conduit hole.

  • The ProtEX-Lite PD663 is Precision Digital's most economical and compact explosion-proof, loop-powered indicator. 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 PD663 carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. It features a single line, four digit, display that can be easily scaled in the field for any 4-20 mA input. The PD663 is built with great looking, modern, die-cast aluminum IP68, NEMA 4X rated enclosure which includes flanges for wall or pipe mounting. This meter is available with an optional backlight feature.


  • Go with the Helios PD2-6000 when you need a large display meter to display the 4-20 ma output from any transmitter you might have. The PD2-6000 can display that output in six full digits and will also provide the 24 VDC to power the transmitter. The PD2-6000's NEMA 4X enclosure, super bright, 1.8" (46 mm) high LEDs, and wide operating temperature range make it perfect for outdoor applications. The PD2-6000 can also be equipped with a 4-20 mA output as well as four relays that can be used for alarming or control applications, including pump alternation control.




    Why you should buy:
  • The PD685 is an easy to use, loop-powered indicator, certified by CSA, ATEX and IECEx as intrinsically safe. The PD685 carries international certifications under both the Class/Division System and Zone System, and is thereby suitable for use in gas and dust hazardous areas worldwide. For Division 2 applications where intrinsically safe interfaces are not needed, the PD685 is able to be installed without barriers! To achieve this ability, the PD685 underwent a special 'nonarcing assessment' under the UL 121201 and CSA C22.2 No. 213 standards, and was determined to be a device incapable of causing an ignition on its own. The PD685 is wellsuited for both indoor and outdoor applications and carries a variety of environmental ratings, including NEMA 4, Type 4X and IP67.

    The PD685 can be seen from considerable distance in bright sunlight or dimly lit areas when the standard backlight feature is activated. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. The meter gets all of the power it needs from the 4-20 mA loop and its 1 V (4 V with backlight) drop results in a minimal burden on the loop. The meter features a wide -40 to 75°C operating temperature range and is available with a ½" conduit hole in a location of your choice for easy installation. Calibration is a quick two-step process involving the adjustment of only two sets of coarse and fine, non-interacting potentiometers.
