Series WWDP Differential Pressure Transmitter

Brand: Dwyer Instruments, LLC
Request Information
Does not ship to United States
The Series WWDP Wet-to-Wet Differential Pressure Transmitter offers everything in one package by having 30 field selectable variations in just 3 models.

The WWDP provides field selectable unidirectional and bidirectional pressure ranges, configurable 0-5, 1-5, 0-10 VDC, and 4 to 20 mA output. It also provides an auto-zero capability.

The field selectable port swap feature eliminates costly replumbing if the unit is improperly installed or if the transmitter is simply replaced. An optional LCD display is available for on-sight indication of line and differential pressure.

The all cast aluminum housing is rated NEMA 4 (IP66).

These features make the WWDP transmitter an ideal instrument for measuring the flow of various liquids and gases, pressure drop across filters, measurement of liquid level or pressurized vessels, and for use in energy management and process control systems.
Features
  • Versatile device for liquid or gas supports designs requiring more precise measurements in support of application
  • Field selectable port swap eliminates costly re-plumbing if unit is re-installed or replaced
  • Uni-directional and bi-directional pressure selection with configurable output provides a single device that can meet broad application needs without having to specify multiple devices
  • Optional LCD display provides local status to identify operational conditions
  • NEMA 4 rated enclosure provides protection in harsh environments permitting outdoor monitoring or in areas where dust and particulate matter exists
