Overview

The PWENC12/14 is a prewired, weather-resistant enclosure that is 12 inches wide and 14 inches tall. It starts with the same enclosure used for our ENC12/14, but then is factory configured with up to eight connectors that are attached to the datalogger or peripherals within the enclosure. Sensors with the appropriate connector are simply attached to connectors on the outside of the enclosure. The PWENC12/14 includes a basic measurement program (created in ShortCut) for the -PW products sold as part of this system. If a more advanced custom datalogger program is required for additional sensors, communications, control, or other needs, an extra fee will be incurred.

Detailed Description

The PWENC12/14 can house one datalogger, power supply, and one or more peripherals (depending on the peripheral’s footprint). You order the sensors, datalogger, power supply, and communication peripherals separately. Compatible sensors, peripheral cables, and solar panels have a –PW extension. 

The PWENC12/14 is shipped with the 7363 enclosure supply kit that consists of desiccant, a humidity indicator card, cable ties, wire tie tabs, putty, grommets, screws, and PVC coupling. Connectors, communication ports, and the enclosure mounting bracket are chosen as options (see Ordering Info).

The PWENC12/14 can be mounted to any of our tripods or towers, or to a user-supplied pipe.

Note: Refer to the Ordering Info on the web page for standard configurations. Nonstandard configurations must be special ordered. It is considered a nonstandard configuration when using a different type, size, or location for any connector, communication port, conduit, cable entry seal, or antenna bulkhead (contact Campbell Scientific for more information).

Compatibility

Peripherals

Our prewired enclosures can house any peripheral that our standard enclosures can house. Equipment that can be attached to the outside of the prewired enclosure include:

  • Sensors—models with an -PW extension are compatible; a -PW version is available for most Campbell Scientific sensors.
  • Digital camera—the cable used to connect a CC5MPX or CC5MPXWD high-resolution digital camera has a -PW cable termination option.
  • AC wall charger—the 22110 Wall Charger (accepts 110 to 240 Vac) has the appropriate connector.
  • Solar panels—Campbell Scientific offers -PW versions of our 10 W, 20 W, 50 W, and 90 W solar panels.
  • Keyboard display—the CR1000KD can be connected via an optional CS I/O port.
  • Laptop—an RS-232 or CS I/O port can be added to the outside of the enclosure allowing laptop connection.
  • Ethernet cable—an optional Ethernet port is offered that supports communications over a local network or a dedicated Internet connection.
  • Antennas—the outside of the enclosure can include connectors for attaching antenna cables.
  • Measurement and control peripherals—cables used to connect our SDMs and multiplexers come in -PW versions.

Frequently Asked Questions

Number of FAQs related to PWENC12/14: 11

Expand AllCollapse All

  1. If you purchased a Stahlin enclosure from Campbell Scientific and it has a failed gasket, we can help you. We will need you to provide an image of the failed gasket, verify the size of your enclousre, and provide your contact information. We can then arrange to have a replacement gasket sent to you from Stahlin. For assistance, contact Technical Support at 435.227.9100.

  2. Components can be easily replaced; however, it may be necessary to do some rewiring and system reprogramming. For assistance with rewiring and reprogramming, contact Campbell Scientific.

  3. Yes. The sensor side of the connector is pn 22018, and the receptacle side is pn 22002.

    Note: Campbell Scientific recommends that only experienced assemblers or installers use the 22018 kit. Anyone using this kit to put the connector on a cable and enclosure should have good assembly skills and the ability to make adjustments as necessary. In addition, a user-supplied product is needed to help seal up the connection (such as epoxy or heat shrink material) so that the seal will endure for its intended lifetime in the environment.

    The cable connection will not have the same result as if Campbell Scientific made the connection because we use a special molding machine to complete the connector/cabling process.  

  4. It depends on the device. Most devices have built-in mounting flanges, but some items require a separate mounting bracket.
  5. Yes. The CD100 mounts in an enclosure door and supports all of the CR1000KD capabilities. With the CD100, historic and real-time data can be read, and instructions can be entered without opening the enclosure door.

    Other available options that display real-time data only are the CD295 and CD294.

  6. Yes. Each enclosure Campbell Scientific sells has a powder-coated backplate with holes on 1 in. centers that match the mounting flanges on our equipment for easy mounting.
  7. There is not an easy way to calculate how much desiccant is needed in an enclosure or how quickly the desiccant will need to be replaced. The following conditions affect the replacement interval:

    • How much humidity the enclosure is exposed to
    • The size of the enclosure
    • How often the enclosure door is opened and how long the door remains open
    • How airtight the enclosure is

    It may be advantageous to use more than one desiccant packet at a time inside an enclosure. Campbell Scientific recommends keeping an extra supply of desiccant on hand for as-needed replacement in the enclosure.

  8. The putty is shipped as part of the 7363 Enclosure Supply Kit. To order an additional 4 ounce container of electrician’s putty, specify pn 6596.

  9. The following information is applicable to many of Campbell Scientific’s standard enclosures and prewired enclosures.

    Note: The procedure below will not work for torn or damaged seals.

    To make a field repair to a loose gasket on an enclosure, first acquire an adhesive, such as standard Gorilla Glue, that is rated for use with polyurethane foam. The adhesive should be compatible with, and recommended for, use with polyurethane foam. Follow these steps:

    1. Pull the gasket away from the gasket channel, being careful not to tear the gasket. The gasket does not need to be removed completely. Rather, remove only those areas that have pulled loose on their own. To keep the gasket up out of the way, lay a small object (such as a toothpick, pen, or pencil) horizontally across the channel.
    2. Using an adhesive that is rated for use with polyurethane foam, apply a small bead of adhesive to the gasket channel. Because the adhesive’s only function is to keep the gasket in place, use it sparingly.
    3. Remove any objects that were holding the gasket out of the way.
    4. Carefully place the gasket in the gasket channel.
    5. Wait 1 to 3 hours for the adhesive to cure before closing the door.
