SBE 37 IMP with Titanium Housing, 1000 dbar Pressure Sensor, Inductive Modem Telemetry, No Oxygen Sensor

MicroCAT C and T (pressure optional) Recorder with Inductive Modem - Includes mooring clamp for jacketed wire, 8 MB Flash memory, lithium battery (non-hazardous), AF24173 Anti-Foulant Devices, Seasoft software, and complete documentation.

37-IM MicroCAT includes:

• Inductive Modem interface
• Memory

Communicating with 1 or more 37-IMs requires use of Sea-Bird Inductive Modem Module (IMM) or Surface Inductive Modem (SIM), which provide serial interface between user’s computer & up to 100 IM instruments coupled to single cable. Purchase IMM/SIM & optional Inductive Cable Coupler (ICC) separately.

• 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)

Cable fits loosely through IM coupling core / wire guide, & is clamped only at mounting clamp. See document 67142. '.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
• 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:

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-IM 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-IM.

• 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.

37-IMP MicroCAT includes:

• Inductive Modem interface
• Memory
• internal, integral Pump — pump provides improved conductivity response & improved anti-foul protection over 37-IM
