Pressure sensor is installed in end cap, & is not field replaceable / swappable. While highest pressure rating gives you most flexibility in using MicroCAT, 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 pressure sensor's full scale range. For example, comparing 2000 & 7000 m sensors:

• 2000 m sensor:
  initial accuracy = 2 m (= 0.1% * 2000 m),
  resolution = 0.04 m (= 0.002% * 2000 m)
• 7000 m sensor:
  initial accuracy = 7 m (= 0.1% * 7000 m),
  resolution = 0.14 m (= 0.002% * 7000 m)

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 XSG/AG connectors. Like XSG/AG connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.

Note: Each interface version of 37-SM has a separate manual.

Cable fits loosely through wire guide, & is clamped only at mounting clamp. See document 67094. '.I' designation indicates that guide and clamp are to be installed on instrument at factory.

Thread for clamping to mooring cable:

• 1/4 in. diameter: 1/4-28 UNF
• 5/16 in./8 mm diameter: 5/16-24 UNF
• 3/8 in. diameter: 3/8-24 UNF
• 1/2 in. diameter: 9/16-12 UNC
• 5/8 in./16 mm diameter: 5/8-18 UNF
• 6 mm diameter: 1/4-20 UNF
• 8 mm diameter: 5/16-24 UNF
• 10 mm diameter: 7/16 -14 UNF
• 12 mm diameter: 1/2-13 UNF

Clamp Size Note: Mooring wire is typically specified by wire size, not by outer diameter (O.D.) of the mooring wire jacket. Verify the wire jacket O.D. before selecting the clamp size. The clamp size must be less than or equal to the wire jacket O.D. but larger than the wire diameter. For example, Mooring System Inc.’s specifications for 3x19 wire rope (in 2016) are as follows:

For mounting on a rope, verify the rope outer diameter, and select a clamp smaller than the rope O.D. to account for the rope compressibility (for example, for 5/16 inch rope, select a ¼ inch clamp; a 5/16 inch clamp will be too large).

See document 67096. '.I' designation indicates that brackets are to be installed on instrument at factory.

One set of batteries is included with standard shipment; 50441 are spares. Batteries are easily accessed by removing 2 screws from connector end cap & pulling out end cap. Shipping restrictions apply for lithium batteries; see SBE 37-SM manual for details. Click here to buy Saft LS 14500 from Amazon.

In 2008, original battery pack was replaced with red top battery holder, which uses 12 AA lithium batteries instead of 50243.1 battery set. See Application Note 89 for details.

801797 is battery holder, without batteries.

Price for 50442, which includes both battery holder (801797) & batteries (50441), is less than price when ordering battery holder & batteries separately. Sea-Bird is helping to absorb some cost for new battery holders by providing a reduced price.

Note: Newer MicroCATs (SMP & IMP with firmware > 4.0, and all IDO & ODO MicroCATs) use a battery pack with a yellow cover plate; the wiring of that pack is different from this one, and cannot be used with SBE 37-SM.

Anti-foulant cap holds AF24173 Anti-Foulant Device in place. This cap, without a hose barb, is a spare, and is intended for use during deployment.
Note: Do not deploy MicroCAT with barbed anti-foulant device cap(s)!

• Cleaning instructions require use of syringe & tubing assembly at intake end of conductivity cell (requiring 1 barbed cap).
• Storage instructions require looping Tygon tubing from end to end of conductivity cell (requiring 2 barbed caps).

Storm shipping case with custom foam inserts holds up to 4 MicroCATs that do not include dissolved oxygen — IMP, IM, SMP, SM, SIP, SI.

• Injection molded case with HPX resin plastic body, recessed wheels, automatic pressure equalization valve, hinged push-button latches, fold-down padded handle, & O-ring seal. Meets airline luggage regulations.
• Inner dimensions:
  29 x 18 x 10.5 inches (74 x 46 x 27 cm).
• Outer dimensions:
  31.3 x 20.4 x 12.2 inches (80 x 52 x 31 cm).

MicroCAT C and T (pressure optional) Recorder with Serial interface, Memory and internal Pump - Includes mooring clamp, 8 MB Flash memory, serial interface, external power input capability (power plus serial on connector), lithium battery (non-hazardous), AF24173 Anti-Foulant Devices, data/power interface cable (cable may be deleted for credit), Seasoft software, and complete documentation.

37-SMP MicroCAT includes:
