Part # Description Notes
53 BPR BOTTOM PRESSURE RECORDER -- With Digiquartz pressure sensor, built-in temperature sensor, 7000 m titanium pressure housing with battery compartment for 12 D cells. Includes 32 MB memory, RS-232 serial interface, frequency input channel for SBE 4M conductivity sensor, 2.5 m data I/O cable (801225), software, & complete documentation. Specify: pressure sensor selection. Photos of standard shipment.
SBE 53 BPR Pressure Sensor Range (approximate maximum depth) Selections -- MUST SELECT ONE
53-1a 10,000 psia (6800 m) Digiquartz pressure sensor Pressure sensor is installed in connector end cap, & is not field-replaceable / swappable. While highest depth rating gives most flexibility in using SBE 53, it is at expense of accuracy & resolution. It is advantageous to use lowest range pressure sensor compatible with your intended maximum operating depth, because accuracy & resolution are proportional to sensor's full scale range. For example, comparing 2000 psia (1300 m) & 10,000 psia (6800 m) sensors:
  • 2000 psia sensor ‑
    initial accuracy is .138 m (= 0.01% * 2000 psia * 0.689 m/psi)
  • 10,000 psia sensor ‑
    initial accuracy is 0.689 m (= 0.01% * 10000 psia * 0.689 m/psi)
53-1b 6000 psia (4000 m) Digiquartz pressure sensor
53-1c 3000 psia (2000 m) Digiquartz pressure sensor
53-1d 2000 psia (1300 m) Digiquartz pressure sensor
SBE 53 BPR High Accuracy External Temperature Option
53-2 High accuracy (0.002 C) external thermistor probe instead of standard internal thermistor Optional high accuracy external thermistor has 0.002 °C accuracy, 0.0001 °C resolution. In comparison, standard internal thermistor has 0.01 °C accuracy, 0.001 °C resolution.
SBE 53 BPR Conductivity Sensor Options
53-3a Conductivity sensor (SBE 4M, titanium housing) - includes cable & mount, anti-foul holders, & AF24173 anti-foulant devices

SBE 4M shown in aluminum housing;
dimensions identical for titanium housing
Standard SBE 53 supports input from optional SBE 4M conductivity sensor through 3-pin bulkhead connector. SBE 4M can be integrated with SBE 53 at our factory, or you can purchase SBE 4M, mount kit, cable, anti-foul holders, & AF24173 anti-foulant devices at a later date & perform integration yourself.

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.
53-3b Delete anti-foulant holder & AF24173 from conductivity sensor option 53-3a (CREDIT)

When included with an SBE 53, SBE 4M includes a fitting on each end to hold an AF24173 Anti-Foulant Device. If you are deploying SBE 53 in an area where you do not think conductivity cell fouling will be a problem, you may delete fittings & anti-foulant devices for credit.
SBE 53 BPR Wet-Pluggable Connector Options
53-4a Wet-pluggable (MCBH) connectors instead of Standard (XSG/RMG) connectors on instrument & data I/O cable (optional conductivity sensor not installed) 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.
Both 53-3 options include wet-pluggable bulkhead connectors on SBE 53 & data I/O cable compatible with wet-pluggable data I/O connector. Option 53-3b also includes additional cost of wet-pluggable bulkhead connector on SBE 4M, & SBE 4M cable with wet-pluggable connectors on both ends.

  
53-4b Wet-pluggable (MCBH) connectors instead of Standard (XSG/RMG) connectors on instrument & data I/O cable (including optional conductivity sensor)
SBE 53 BPR Spares & Accessories
801225 Data I/O cable, Standard connector (RMG-4FS) with DB-9S, 2.5 m (DN 32421) These test cables are used for setting up system & uploading data from memory after recovery. Applicable cable is included with SBE 53; listing here is for spare cable.
801374 Data I/O cable, Wet-pluggable (MCIL-4FS) with DB-9S, 2.5 m (DN 32715)
20200 USB to Serial Port Adapter, FTDI UC232R-10 (connects computers with USB ports to RS-232 instruments) Many newer PCs & laptop computers have USB port(s) instead of RS-232 serial port(s). USB serial adapter plugs into USB port, & allows a serial device to be connected through adapter. Multi-port adapters are available from other companies; see Application Note 68.
801542 AF24173 Anti-Foulant Device pair (spare, bagged, labeled for shipping)
50315 --

50315 provides fittings (2) to hold AF24173 Anti-Foulant Devices at each end of optional SBE 4M 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 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 AF24173 Anti-Foulant Devices 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 2002 include 50315 installed on SBE 4M. Order 801542 AF24173 Anti-Foulant Devices as needed.
Useful life of AF24173 Anti-Foulant Devices varies, depending on several factors. We recommend that customers consider more frequent replacement when high biological activity & strong current flow (greater dilution of anti-foulant concentration) are present. Moored instruments in high growth & strong dilution environments have been known to obtain a few months of quality data, while drifters that operate in non-photic, less turbid deep ocean environments may achieve years of quality data. Experience may be strongest determining factor in specific deployment environments.
50315 Anti-foul holder kit - installs on SBE 4M to allow use of AF24173 in place of obsolete 24012 Anti-Foulant Devices. Order AF24173 separately.

  • Mount bracket 50286 included if SBE 53 is ordered with SBE 4M (option 53-3a); this is spare.
  • Cable 17695 included if SBE 53 is ordered with SBE 4M (option 53-3a); this is spare.
  • Cable 171752 included if SBE 53 is order with SBE 4M (option 53-3a) & wet-pluggable connectors (option 53-4b); this is spare.

171752 SBE 4 to SBE 26/26plus/53 interface cable, Wet-pluggable (MCIL-3FS to MCIL-3FS), 28 cm (DN 32671)
801575 Battery Cover Spacer / Adapter, 12 D alkaline cells to 6 DD Electrochem Lithium cells This battery cover spacer/adapter is required if using DD lithiums (six DD drop-in batteries with buttons), because 1 lithium DD battery is shorter than 2 alkaline D batteries.
Note: Sea-Bird does not supply Electrochem lithium batteries; you must purchase them elsewhere (see WGT's website for purchasing information). Shipping restrictions apply for Electrochem lithium batteries & assembled battery packs.
