SENSORS

      Although Teledyne manufactures over 160 sensor configurations the more popular versions for diving are the K-1D (See note below), R17D, and, the R22D.  An overview of their full range of diving sensors are listed here.  

     The differences I'm aware of between the R17D and the R22D are that the R22D comes with gold plated contacts and three pin Molex connectors while the R17D comes with nickel plated contacts and a mono-plug connector.

K-1D            R22D

NOTE:  It should be noted at this date, 3/05, that the the K-1D is available although I noticed that only the K1 is listed in the above documentation and that currently there is not technical PFD file available.  The difference between the K-1 and K-1D being that the K-1D has a hydrophobic membrane.
