Section 4 Overview
4.1 Operation
The SBE 37 MicroCAT measures conductivity (C) and temperature (T).
Optional equipment includes:
• Pressure (depth)
• Internal pump
• Optical Dissolved Oxygen (ODO)
The sensor can operate as a stand-alone or is easily integrated with other platforms.
If so equipped, the internal pump operates for one second each time the sensor collects a
sample. The internal pump has several advantages over sensors without pumps:
• The pump flushes the water from the flow path after each sample and quickly moves
a new sample into the flow path so that conductivity and oxygen measurements are
more accurate.
• Water does not flow freely through the flow path so it stays saturated with the anti-
fouling chemicals.
• The ODO sensor (SMP-ODO only) is integrated in the flow path to better align with
the CTD measurement.
The user can operate the sensor in one of several modes:
Autonomous
• Operates at user-selected intervals (10–21600 seconds).
• Transmits data real-time if #iiTxRealTime=Y.
• Operation sequence:
1. The pump operates for one second (uses #iiMinCondFreq=)
2. The sensor makes one measurement
3. The data is stored internally
4. The sensor goes into a low power mode until the next sample is collected.
Polled operation
• Polled data collection is useful when the sensor is integrated with satellite, radio, or
wire telemetry equipment.
• Operation sequence:
1. The pump operates on command for one second
2. The sensor makes one measurement
3. The sensor sends the data to the controller
4. The sensor goes into a low power mode until the next command to operate.
There are two ways to deploy the sensor.
1. Cable installed—the sensor is controlled remotely and transmits data on command.
The sensor can also operate autonomously and transmit data at a user-set interval.
Data can be transmitted while the sensor is deployed.
2. Dummy plug installed—the interval at which data is collected is set by the user before
deployment. Data is transmitted to a PC after deployment.
4.2 Sample times
The time it takes for the MicroCAT to collect a sample depends on several factors, such
as the data collection mode, and whether the optional pressure sensor is installed.
11

The time that shows with the data is the time at the start of the sample. For example, if
the sensor is set to sample at 12:00:00, the stored time shown in the data will be
12:00:01 or 12:00:02.

No pressure sensor 2.0 sec 2.0 sec 2.7 sec
Pressure sensor — 2.6 sec 3.1 sec
Communications time, the time it takes to request and transmit data with the Dataii
command: 0.5 seconds.
4.3 Battery life
The battery pack is 4 cells in series of 3 parallel strings. The battery holder has a yellow
cover plate. It is NOT compatible with the older battery holder that has a red cover plate.
The manufacturer recommends the user uses a conservative capacity value:
• SM, SMP—8.8 amp-hours, even though the nominal capacity is calculated at 10.6 A-
hours.
• SMP-ODO—6.0 amp-hours, even though the nominal capacity is calculated at 7.8 A-
hours.
The current draw varies if the sensor is set to transmit data in real-time (15 mA) or not
(13 mA). The current draw of the pump is 0.026 µA-seconds per pulse (1.0 second
pulse). Low power current draw is 30 µA (0.26 amp-hours/year).
The time required for each sample depends on the user-set data collection mode, and
whether the MicroCAT has a pressure sensor. The MicroCAT is shipped with Deployment
Endurance Calculator software to calculate the maximum deployment time. An example
of a manual calculation is shown below.
Example: 10 SBE 37 SMPs with pressure sensors are set up to take a sample every 10 minutes, or 6 samples/hour. Real-
time data is requested once every hour. How long can it be deployed?
Autonomous sample time = 2.4 seconds
Current draw for data collection = 0.013 A × 2.4 seconds = 0.031 A-seconds/sample
6 × 0.031 = 0.19 A-seconds/hour
Polled sample time (with pressure sensor) = 2.6 seconds
In one hour, 1 sample with GData = 0.015 A × 2.6 seconds = 0.04 A-seconds/hour
Pump operation current draw = 0.026 A-seconds/pulse
In one hour, pump current = (6 autonomous + 1 GData sample) × 0.26 A-seconds/sample = 1.82 A-seconds/hour
Communication current draw/query = 0.15 mA × 0.5 seconds/MicroCat queried × 10 MicroCATs on line = 0.001 A-
seconds/hour
Low power current draw = 30 µA, or 0.03 mA
In 1 hour, 0.03 mA × 3600 seconds/hour = 0.11 A-seconds/hour
Total current draw/hour = 0.19 + 1.82 + 0.0011 + 0.11 = 2.12 A-seconds/hour
Capacity = (8.8 A-hours × 3600 seconds/hour) ÷ 2.12 A-seconds/hour = 14900 hours = 622 days = 1.7 years
Number of samples = 14900 hours × 6 samples/hour = 89400 samples
Overview
12

Example: 10 SBE 37 SMP-ODOs with pressure sensors are set up to sample autonomously and take a sample every
10 minutes, or 6 samples/hour (GData and Dataii). Real-time data is requested once every hour. Adaptive Pump Control is
enabled. Deployment is at approximately 500db, at a temperature of approximately 10 °C. OxTau20 is manufacturer-set at
5.5. OxNTau is 7.0. How long can they be deployed?
CTD-DO operation 0.155 watts × 2.8 second sample time = 0.434 Joules/hour
In one hour, operation power draw = 6 samples/hour × 0.434 Joules/sample = 2.60 Joules/hour
Pump
ft = A + (B × T) + (C × T2) = 2.549 + (-1.106 × 10-1 × 10) + (1.571 × 10-3 × 10 ×10) = 1.600
fp = e(pcor × P) = e(1.45e-4 × 500) = 1.075
tau = OxTau20 × ft × fp = 5.5 × 1.600 × 1.075 = 9.46
Pump time = OxNTau × tau = 7.0 × 9.46 = 66.2 seconds (> minimum pump time of 3 seconds)
In one hour, pump current = (6 autonomous + 1 GData sample) × 0.26 A-seconds/sample = 1.82 A-seconds/hour
Pump operates for an additional 2.8 seconds during data collection.
Pump operation, 0.12 watts × (66.2 + 2.8 seconds) = 8.28 Joules/sample = 49.68 Joules/hour
CTD-DO in standby, pump operates = 0.016 watts × 66.2 seconds = 1.06 Joules/sample
ln one hour, power draw = 6 samples/hour × 0.16 Joules/sample = 6.36 Joules/hour
CTD-DO in standby, between samples = 0.0004 watts × (600 - [66.2 + 2.8]) seconds = 0.21 Joules/sample
In one hour, power draw = 6 samples/hour × 0.21 Joules/sample = 1.26 Joules/hour
Additional sample taken one per hour with Gdata approximately 0.434 Joules/sample + 8.28 Joules/sample =
8.72 Joules/hour
Communications = 0.065 watts × 0.5 seconds/MicroCAT × 10 MicroCATs on line =0.32 Joules/hour
Total power draw/hour = 2.60 + 49.68 + 6.36 + 1.26 + 8.72 + 0.32 = 68.94 Joules/hour
Battery pack capacity
Nominal voltage of 14 V and 85% DC-DC converter efficiency
14 V × 6 amp-hours × 3600 seconds/hour × 0.85 = 257040 Joules
Capacity = 257040 Joules ÷ 68.94 Joules/hour = 3728 hours = 155 days = 0.42 years
Number of samples = 3728 hours × 6 samples/hour = 22368 samples
4.4 Cable length and external power
The sensor can use an external power source that supplies 9–24 VDC in addition to or
instead of the internal batteries. The MicroCAT uses power from the source that supplies
the highest voltage.
Calculate the maximum cable length after IR loss to make sure that an external power
source supplies enough voltage to the MicroCAT.
For 37 SM and 37 SMP:
• Supply a minimum of 10 V, after IR loss, so the MicroCAT does not get any power
from the internal batteries. V - IR > 10 V.
• Supply a minimum of 9 V, after IR loss, so the MicroCAT uses the internal batteries,
or if no batteries are installed. V - IR > 9 V.
• I = required communication current = 0.5 amps
What is the maximum cable length needed to supply 12 volts of power from an external power source to the SM or SMP with
20 gauge wire?
12 V - 0.5 amps × (0.0107 ohms/ft × 2 × cable length) > 9 V
3 V > 0.5 amps × (0.0107 ohms/ft × 2 × cable length) = cable length 280 ft (85 m)
For 37 SMP-ODO:
• Supply a minimum of 16 V, after IR loss, so the MicroCAT does not get any power
from the internal batteries. V - IR > 16 V.
Overview
13

• Supply a minimum of 9 V, after IR loss, so the MicroCAT uses the internal batteries,
or if no batteries are installed. V - IR > 9 V.
• I = required communication current = 0.25 amps
What is the maximum cable length needed to supply 12 volts of power from an external power source to the 37 SMP-ODO
with 20 gauge wire?
12 V - 0.25 amps × (0.0107 ohms/ft × 2 × cable length) > 9 V
3 V > 0.25 amps × (0.0107 ohms/ft × 2 × cable length) = cable length 560 ft (170 m)

5.2 Install batteries
WARNING
Explosion hazard. If the batteries are not installed correctly, explosive gases can be
released. Make sure that the batteries are of the same approved chemical type and are
inserted in the correct orientation.
WARNING
If the user thinks that a sensor has water in the pressure housing: Disconnect the
sensor from any power supply. Put on safety glasses and make sure that the sensor is
pointed away from the body and other people. In a well ventilated area, use the purge
port (if the sensor is so equipped), or very SLOWLY loosen the bulkhead connector to
let the pressure release.
WARNING
If the user thinks that the lithium batteries have leaks, pressure may have built up inside
of the pressure housing. Follow ESD protocols to release internal pressure. Put on
safety glasses and protective gloves and make sure that the sensor is pointed away
from the body and other people. In a well ventilated very SLOWLY loosen the bulkhead

3. Install these two screws into the sides of the end flange to start to loosen the end
flange.
4. If necessary, hold the bulkhead connector with a crescent wrench to make it easier to
turn the end flange.
5. Turn the end flange counter-clockwise to loosen it from the pressure housing.
6. Pull gently to disconnect the battery wires in the end flange from the battery pack.
7. Use a lint-free tissue to remove any water from the O-ring surfaces inside the
pressure housing and end flange.
8. Use a 7/64" hex key to loosen the captured screw in the battery cover plate.
9. Remove the battery pack from the pressure housing.
10. Turn the yellow cover plate counterclockwise to remove it from the battery pack body.
11. Move each of the two O-rings on the outside of the battery holder from the grooves.
It makes it easier to remove or insert batteries.
12. Examine the O-rings and surfaces for dirt, cuts, or other damage.
Clean or replace as necessary.
13. If necessary, remove the size AA batteries in the pack.
14. Insert new batteries.
Make sure to alternate the positive (+) and the negative (-) ends on the size AA
batteries to agree with the labels on the pack as they are installed.

assembly with the circuit board in the pressure housing.
19. Use a 7/64" hex key to tighten the captured screw on the yellow battery cover onto
the shaft in the pressure housing.
20. Attach the Molex connector on the end flange to the connector in the pressure
housing.
21. Examine the O-rings on the end flange. They must be pristine, with no lint or
scratches or chips.
• Apply a small quantity of Parker Super O Lube® to any new O-rings.
22. Align the end flange holes with the holes in the pressure housing.
23. Carefully push the end flange into the pressure housing.
It may help to rotate the end flange so that the wires do not bend too much.
24. If necessary, use a 9/64" hex key to remove the two screws from the end flange.
25. Use a 9/64" hex key to install the two screws into the pressure housing of the sensor
again.
5.3 Install software and test sensor
Make sure that the sensor is connected to a power supply and PC through the serial
connector on the supplied cable. Most PCs no longer have serial ports, and a serial-to-
USB adapter is necessary. Make sure that the USB driver software is installed on the PC
so that there is communication between the sensor and the PC.
1. Install the Seasoft V2 software from the manufacturer-supplied CD.
2. Remove the dummy plug from the sensor.
3. Connect the I/O cable to the sensor and to the PC and a power supply (9–24 VDC).
4. Supply power to the sensor.
