Accessories & Modifications

  • The PDX6901 is a 0.01μF/470Ω snubber with flexible leads intended to prolong the life of the relays on Precision Digital products as well as protect against electrical noise caused by switching inductive loads.

  • The PDA7420 Trident meter copy cable connects two Trident meters together so the programming from one Trident can be copied to the other. No additional serial adapters are required.

  • The PDX765 Trident Power Supply & Option Upgrade Kit is a simple way to upgrade your Trident meter with new functions and features. The PDX765 is available in several different models to allow every possible Trident configuration. Options include the input power supply, transmitter supply, 4-20 mA output, and relays.
  • The PDA7422 Trident RS-485 serial adapter converts the serial output of the PD765 Trident meter to balanced, full or half-duplex RS-422 or RS-485 signals.

  • The PDWA3100 extension cables are used to extend the distance between the Yagi Antenna and the PDW30 or PDW90 wireless units. The extension cables come in 20-foot and 40-foot lengths and include an antenna coupler to connect the PDW wireless device to the antenna extension cable, coax seal tape, and a 3/4" NPT cable gland.

    PDWA3120-N or PDWA3140-N
  • The PDWA3900 Yagi antennas are made to work with point-to-point and point to multi-point applications.

    These high gain antennas are ideal to use with Precision Digital's PDW series because they give you the flexibility of installing the antenna exactly where you need to bridge your point-to-point or point to multi-point wireless process signals while keeping the PDW unit in a convenient location for monitoring.

    Each Yagi antenna is factory tuned on a network analyzer for best power match and lowest VSWR, offering the best possible performance.

    The PDWA3900 also comes complete with a mounting kit that includes stainless steel hardware.

    Extension cable accessories are available to extend the distance between the Yagi antenna and the PDW30 or PDW90 wireless units. See Ordering Information for details.
