|SBE 37-SMP-IDO Mooring Clamp Wire Size Selections (Specify clamp to match O.D. of mooring wire jacket) -- MUST SELECT ONE|
|37SMP-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
Thread for clamping to mooring cable:
|37SMP-1b||Wire guide & mounting clamp for 5/16 in. diameter mooring wire|
|37SMP-1c||Wire guide & mounting clamp for 3/8 in. diameter mooring wire|
|37SMP-1d||Wire guide & mounting clamp for 1/2 in. diameter mooring wire|
|37SMP-1e||Wire guide & mounting clamp for 6 mm diameter mooring wire|
|37SMP-1f||Wire guide & mounting clamp for 8 mm diameter mooring wire|
|37SMP-1g||Wire guide & mounting clamp for 10 mm diameter mooring wire|
|37SMP-1h||Wire guide & mounting clamp for 12 mm diameter mooring wire|
|37SMP-1i||Wire guide & mounting clamp for 16 mm (5/8 in.) diameter mooring wire|
|37SMP-1j||Alternative mounting - plastic brackets to provide through-bolt mounting to a flat surface||See document 67218.|
|SBE 37-SMP-IDO ShallowCAT Option -- Plastic (PET-P) Housing with 250 meter depth rating|
|37SMP-2||250 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-SMP-IDO Pressure Sensor Range (Depth) Options|
|37SMP-3a||20 m strain gauge pressure sensor||
sensor is installed in end cap, & is not field replaceable / swappable. While highest
pressure rating gives you most flexibility in using 37-SMP-IDO, 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 --
|37SMP-3b||100 m strain gauge pressure sensor|
|37SMP-3c||350 m strain gauge pressure sensor|
|37SMP-3h||600 m strain gauge pressure sensor|
|37SMP-3d||1000 m strain gauge pressure sensor|
|37SMP-3e||2000 m strain gauge pressure sensor|
|37SMP-3f||3500 m strain gauge pressure sensor|
|37SMP-3g||7000 m strain gauge pressure sensor|
|SBE 37-SMP-IDO Alternate Serial Interface Option|
|37SMP-5||RS-485 (half duplex ONLY) serial interface (replaces RS-232 interface)||
Two-wire, RS-485 interface provides communication
with individual 37-SMP-IDO or with all 37-SMP-IDOs 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-SMP-IDO have separate manuals; see manual links at top of page.
|SBE 37-SMP-IDO Wet-Pluggable Connector Option|
|37SMP-6b||Wet-pluggable (MCBH) connector instead of Standard (XSG) connector (includes data/power interface cable)||
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.37SMP-6b includes a data/power interface cable compatible with wet-pluggable connector.
|SBE 37-SMP-IDO Storm Shipping Case Option -- holds up to 3 SBE 37-SMP-IDOs|
|37SMP-7I||Storm shipping case (iM2950) instead of standard wood crate -- holds up to 3 SBE 37-SMP-IDOs||
Price for 37SMP-7I reflects a credit for deletion of our standard wood crate.
|SBE 37-SMP-IDO Spares & Accessories|
|801542||AF24173 Anti-foulant Device (pair, bagged, labeled for shipping)||
devices fit into anti-foulant device cups at
conductivity cell intake and plumbing exhaust, under the
conductivity cell guard. 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-SMP-IDO
801863 is battery holder,
without batteries. Battery holder is included with standard
shipment; this is a spare.
|801863||Yellow top battery holder (14V nominal, Version 2) for use with twelve 3.6V AA lithium cells, for pumped SBE 37 (SMP & IMP with firmware version > 4.0 & all SMP-ODO, IMP-ODO, SMP-IDO, & IMP-IDO)|
|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 37SMP-6b specified; 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.|
|TBD||Storm shipping case (iM2950) -- holds up to 3 SBE 37-SMP-IDOs||
