Part # Description Notes
4M MOORED CONDUCTIVITY SENSOR - - modular sensor (square wave output & isolated electronics), range 0 - 7 S/m. Includes complete documentation. Specify: housing (depth rating) selection.


Aluminum housing shown
SBE 4M is shipped with Tygon tubing looped end-to-end around conductivity cell, to prevent dust & dirt from entering cell. SBE 4M is shipped dry to prevent conductivity cell damage from freezing.

See SBE 4C for conductivity sensor with a Quick disconnect feature, intended for easy attachment to plumbing in SBE 9plus or 25 CTD.
SBE 4M Housing (depth rating) Selections -- MUST SELECT ONE
4M-1 Aluminum housing, 3400 m depth rating

 
4M-2 Aluminum housing, 6800 m depth rating
4M-3 Titanium housing, 10,500 m depth rating
SBE 4M Wet-Pluggable Connector Option
4M-4 Wet-pluggable (MCBH) connector instead of Standard (XSG) connector  
Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on connector pins is forced out as connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to our standard (Impulse XSG/RMG) connectors. Like standard connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.
SBE 4M Spares & Accessories
50315 Anti-foul holder kit - installs on SBE 4, & SEACATs (not SEACATplus) to allow use of AF24173 in place of obsolete 24012 Anti-Foulant Devices. Order AF24173 separately.

50315 --
slide Tygon on end of conductivity cell
50315 provides fittings (2) to hold AF24173 Anti-Foulant Devices at each end of conductivity cell. See Application Note 70: Installing Anti-Foulant Device Mount Kit on SBE 4, 16, 19, and 21 Conductivity Cells.
  • SBE 4Ms shipped with optional Anti-Foulant Devices for moored applications before October 2002 used a smaller anti-foulant device inside Tygon tubing that attached to end of conductivity cell, & did not include 50315. For those SBE 4Ms, order 50315 & 801542 first time you need new Anti-Foulant Devices. Once you have 50315, order 801542 AF24173 Anti-Foulant Devices as needed.
  • SBE 4Ms shipped with optional Anti-Foulant Devices for moored applications after October 2002 include 50315 installed on SBE 4M. Order 801542 AF24173 Anti-Foulant Devices as needed.
801542 AF24173 Anti-foulant Device (pair, bagged, labeled for shipping)
17086 SBE 4 (Cond) or SBE 3 (Temp) to SBE 9plus/25 interface cable, 0.63 m (DN 30566) Cable for connecting SBE 3plus or 3F Temperature Sensor or SBE 4C Conductivity Sensor to SBE 9plus or 25 CTD. Connector type (standard) must match sensor and CTD. For cable with wet-pluggable connectors, order PN 171669 (DN 32671) instead
50083.1 Aluminum TC Sensor Mounting Kit for SBE 9plus For mounting SBE 3plus or 3F Temperature Sensor and SBE 4C Conductivity Sensor on SBE 9plus or 25 CTD.
90085 TC duct & plumbing kit for user installation (includes documentation) See Application Note 15: TC Duct Assembly and Plumbing Installation for details.
23557 Quick disconnect connector, for 7/16" diameter tubing (connects to conductivity cell) 23557 mounts to tube fitting & connects to end of SBE 4C conductivity cell. When used with 23555 (below), provides quick disconnect for removing plumbing from conductivity cell (used on SBE 9plus or 25 CTD).
23555 Quick disconnect connector, for 1/2" diameter tubing (inserts into Tygon tubing) 23555 snaps onto 23557 & attaches to Tygon tube plumbing, providing quick disconnect for removing plumbing from SBE 4C conductivity cell (used on SBE 9plus or 25 CTD).
50286 SBE 4 mounting bracket for SBE 26/26plus/53 SBE 4M can be used to provide optional conductivity for SBE 26 / 26plus Wave & Tide Recorder or SBE 53 BPR Bottom Pressure Recorder. PN 50286 mounts SBE 4M on 26 / 26plus / 53. PN 17695 provides interface if instruments have standard connectors; PN 171752 provides interface if instruments have wet-pluggable connectors.
  • SBE 4M, mounting bracket, & interface cable are included with 26plus if 26plus is ordered with option 26p-3c.
  • SBE 4M, mounting bracket, & interface cable are included with SBE 53 if SBE 53 is ordered with option 53-3a.
17695 SBE 4 to SBE 26/26plus/53 interface cable (RMG-3FS to RMG-3FS), 0.3 m (DN 30566)
171752 SBE 4 to SBE 26/26plus/53 interface cable, Wet-pluggable (MCIL-3FS to MCIL-3FS), 0.3 m (DN 32671)
