FIGURE 1-2. The CRVW3-NE 3-Channel Vibrating-Wire Datalogger
The CRVW3 is available in both enclosure and non-enclosure versions. The
standard CRVW3 is packaged inside a protective enclosure. On-board power
support for a rechargeable battery (including a built-in charge regulator) or
non-rechargeable D-cells is included. The non-enclosure version, the
CRW3-NE, comes without the enclosure and battery. While this manual refers
mainly to the enclosure version, the configuration is identical for both models.
Multiple built-in radio options (–RF407, –RF412, –RF422, –RF427, and
–RF451) are available to enable the creation of wireless networks. All radio
options except the –RF427 are available in both enclosure and non-enclosure
versions. The –RF427 is only available in the non-enclosure version.
