Descripción detallada
The ClariVue 10 is an ISO 7027-compliant, side-scatter turbidity sensor. It returns data via SDI-12 to a data logger. Turbidity is a common surrogate measurement for suspended sediment concentration in aquatic systems. The ClariVue 10 is designed to operate in fresh and saline environments. It will require regular maintenance to keep the optical window clean in high bio-fouling environments. The face of the sensor is made from copper to slow biological growth over the optical windows.

The CR5000 does not natively support communication with serial sensors; however, SDM-SIO1 modules can be added to collect data from serial sensors.
-
The SDM-SIO1 has lower power biasing of its inputs and no internal termination resistors, so it operates in the lowest power state. However, this means it can quite easily detect noise on the RS-422 cable, which can, for instance, be picked up from power leads. A simple solution to this is to add 120R termination resistors at one or both ends of the cable. Although termination resistors are only normally needed on long cable runs, they are also quite effective at reducing noise.
-
The SDM-SIO1 acts as a virtual serial terminal to a CRBasic data logger. The data logger’s serial functions can be used to control the device.
-
Yes. This feature was added in 2013. Ensure that both the data logger operating system and the SDM-SIO1 firmware are up to date. Using an SDM-SIO1, the data logger can be a Modbus client or server, although the intended and most common use is for client operation. In CRBasic, use the SerialOpen() instruction to configure the SDM-SIO1 interface and the ModBusClient() instruction to issue Modbus commands.
-
An interface is required. This can be done using an SDM-SIO1, or a third-party RS-422 to RS-232 converter.
-
Use four SDM-SIO1s or a single SDM-SIO4.
-
It depends. It is possible to connect serial sensors to a datalogger without the use of an SDM-SIO4. However, if the sensors require hardware flow control or true RS-232 voltage levels, an SDM-SIO4 may be needed. The SDM-SIO1 also works with RS-485 signals and is a preferred alternative to the SDM-SIO4.
-
The MD485 RS-485 Multidrop Interface is a general communication interface or serial converter. Additionally, the MD485 can be used without a datalogger and offers collision avoidance for PakBus communications.
The SDM-SIO1 Serial Input/Output Module is designed for acquiring data from smart serial sensors, rather than for general communications like data collection or program downloads. The SDM-SIO1 can operate in half- and full-duplex modes, has a smaller form factor, works with RS-422, and can be daisy-chained in quantities of up to 15 on a single three-wire SDM port.
-
The CR1000, CR3000, and CR800-series dataloggers can be used to collect and process binary data from smart sensors via serial or TCP/IP socket connections. In some cases, a converter or communications peripheral may be required.
Note: The capabilities mentioned above are not available for the CR200X-series, CR5000, and CR9000X dataloggers.

ClariVue SDI-12 Program Example (1 KB) 11-08-2021
This example CR1000X program uses the M1! SDI-12 command to retrieve 100 burst measurements from a ClariVue 10 or ClariVue 20. The sensor makes 100 measurements to calculate turbidity statistics (median, mean, standard deviation, minimum, maximum) and mean temperature.
