||
SBE 37-SM Mooring Clamp Wire Size Selections (Specify clamp to match O.D. of mooring wire jacket) -- MUST SELECT ONE | ||||
37SM-1a | Wire guide & mounting clamp for 1/4 in. diameter mooring wire |
Cable fits loosely through wire guide, & is clamped
only at mounting clamp. See document
67094. Thread for clamping to mooring cable:
|
||
37SM-1b | Wire guide & mounting clamp for 5/16 in. diameter mooring wire | |||
37SM-1c | Wire guide & mounting clamp for 3/8 in. diameter mooring wire | |||
37SM-1d | Wire guide & mounting clamp for 1/2 in. diameter mooring wire | |||
37SM-1e | Wire guide & mounting clamp for 6 mm diameter mooring wire | |||
37SM-1f | Wire guide & mounting clamp for 8 mm diameter mooring wire | |||
37SM-1g | Wire guide & mounting clamp for 10 mm diameter mooring wire | |||
37SM-1h | Wire guide & mounting clamp for 12 mm diameter mooring wire | |||
37SM-1i | Wire guide & mounting clamp for 16 mm (5/8 in.) diameter mooring wire | |||
37SM-1j | Alternative mounting - plastic brackets to provide through-bolt mounting to a flat surface | See document 67096. | ||
SBE 37-SM ShallowCAT Option -- Plastic (PET-P) Housing with 350 meter depth rating | ||||
37SM-2 | 350 m plastic housing instead of standard titanium housing (CREDIT) | Substituting plastic housing for standard 7000 m titanium housing provides lower cost option for shallow deployments. | ||
SBE 37-SM Pressure Sensor Range (Depth) Options | ||||
37SM-3a | 20 m strain gauge pressure sensor |
Pressure
sensor is installed in end cap, & is not field replaceable / swappable. While highest
pressure rating gives you most flexibility in using 37-SM, 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 --
|
||
37SM-3b | 100 m strain gauge pressure sensor | |||
37SM-3c | 350 m strain gauge pressure sensor | |||
37SM-3h | 600 m strain gauge pressure sensor | |||
37SM-3d | 1000 m strain gauge pressure sensor | |||
37SM-3e | 2000 m strain gauge pressure sensor | |||
37SM-3f | 3500 m strain gauge pressure sensor | |||
37SM-3g | 7000 m strain gauge pressure sensor | |||
SBE 37-SM Alternate Serial Interface Option | ||||
37SM-5 | RS-485 (half duplex ONLY) serial interface (replaces RS-232 interface) |
Two-wire, RS-485 interface provides communication
with individual 37-SM or with all 37-SMs attached to RS-485
interface. This allows for coordination of sampling among many
instruments. However, note that half-duplex communication is
one-direction at a time (i.e., you cannot send commands & receive
data at same time). Note that RS-232 & RS-485 versions of 37-SM have separate manuals; see manual links at top of page. |
||
SBE 37-SM Wet-Pluggable Connector Option | ||||
37SM-6b | Wet-pluggable (MCBH) connector instead of Standard (XSG) connector (includes data/power interface cable 801206) |
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. 37SM-6 includes a data/power interface cable compatible with wet-pluggable connector. |
||
SBE 37-SM Storm Shipping Case Option -- holds up to 4 SBE 37-SMs | ||||
37SM-7 | Storm shipping case (iM2950) instead of standard wood crate -- holds up to 4 SBE 37-SMs |
Storm
shipping case with custom foam inserts holds up to 4
MicroCATs that do not include dissolved oxygen -- IMP, IM, SMP, SM, SIP, SI.
Price for 37SM-7 reflects a credit for deletion of our standard wood crate. |
||
SBE 37-SM Spares & Accessories | ||||
801542 | AF24173 Anti-Foulant Device pair (spare, bagged, labeled for shipping) |
Anti-foulant
devices fit into anti-foulant device cups at each end of
conductivity cell. Anti-foulant devices included with standard
shipment; these are spares. Useful life 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. |
||
50441 | SBE 37 & 44 lithium batteries (spare), package of twelve 3.6V AA cells (Saft LS 14500) |
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 (RS-232
or RS-485)
for details. In July 2008, original battery pack was replaced with red top battery holder, which uses 12 AA lithium batteries instead of 50243.1 battery set. See MicroCAT Change Notice and 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.
|
||
801797 | Red top battery holder (7V nominal, Version 1) for use with twelve 3.6V AA lithium cells, for SBE 37 (SM, SMP, IM, IMP with firmware version < 4.0) & SBE 44 | |||
50442 | Red top battery holder (7V nominal, Version 1) (PN 801797) and twelve 3.6V AA lithium cells, for SBE 37 (SM, SMP, IM, IMP with firmware version < 4.0) and SBE 44 | |||
233540 | Anti-foulant cap without hose barb, black (for use with SBE 37 [SM, SMP, IM, IMP, SI, SIP] with firmware version < 4.0) |
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)! |
||
50087.1 | Cell filler/storage device with hose barbs (Application Note 34) |
This kit includes a syringe & tubing assembly, & 2
anti-foulant device caps with hose barbs. Remove installed
anti-foulant device cap(s) & replace them with caps with hose barbs
for cleaning & storage only.
|
||
801385 | Data/Power interface cable, RMG-4FS to DB-9S & red/black twisted wire leads, 2.4 m (DN 32277) |
801385 -- Included with standard shipment;
this is spare.
801206 -- Included with standard shipment if 37SM-6b specified (wet-pluggable connector); this is spare. |
||
801206 | Data/Power interface cable, Wet-Pluggable, MCIL-4FS to DB-9S & red/black twisted wire leads, 2.4 m (DN 32366) | |||
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. | ||
233186 | High-head pressure port plug for muddy/biologically productive environments (Application Note 84), for use with SBE 37 [SM, SMP, IM, IMP, SI, SIP] with firmware version < 4.0 | This pressure port plug extends beyond surface of instrument end cap, and has 4 horizontal vent holes connecting internally to a vertical vent hole. Horizontal orientation of external holes prevents deposit of sediment inside pressure port. Each of the 4 vent holes is larger than single vent hole in standard pressure port plug, significantly reducing possibility that biological growth will cover all holes. See Application Note 84: Using Instruments with Druck Pressure Sensors in Muddy or Biologically Productive Environments. | ||
31632 | Storm shipping case (iM2950) -- holds up to 4 SBE 37-SMs |
Storm
shipping case with custom foam inserts holds up to 4
MicroCATs that do not include dissolved oxygen -- IMP, IM, SMP, SM, SIP, SI.
