    Safety section at the back of this manual. Although the CS230/CS231 is designed to be a rugged and reliable device for field use, care should be taken when handling or moving it to avoid damage. There are no user-serviceable parts and disassembling the device will void the warranty.

    . It is included in installations of LoggerNet, RTDAQ, and PC400. The following procedure also shows using Short Cut to program the CS230/CS231. 1. Open Short Cut and click Create New Program. 2. Double-click the data logger model. 3. In the Available Sensors and Devices box, type CS231 or locate the sensor in the Sensors >...
  • Page 6 4. Click the Wiring tab to see how the sensor is to be wired to the data logger. Click OK after wiring the sensor. 5. Repeat steps 3 and 4 for other sensors. 6. In Output Setup, type the scan rate, meaningful table names, and Data Output Storage Interval. CS230/CS231 Temperature Profilers...

  • Page 7: Overview

    The CS230/CS231 temperature profiler uses digital sensor technology allowing for a simple 3-wire integration. The CS230/CS231 consists of a rigid probe assembly and up to four optional external temperature probes. The rigid probe assembly maintains the precise position of the temperature points within the profile, while protecting the temperature sensors in all mediums.

    Second sensor from tee: 420 s Remainder of profiler: 300 s Maximum sensors per probe: 32 sensors in rigid probe assembly, 4 external sensors External probe length: 45 cm (18 in) Supply voltage: 9 to 28 VDC CS230/CS231 Temperature Profilers...

  • Page 9: Installation

    (p. 2) for a Short Cut tutorial. 7.1 Siting Install the CS230/CS231 directly in the medium that is to be measured. The types of medium that can be measured are varied, including soils, roadbeds, and water. To make the most representative measurement, it is important that consistent contact be made between the temperature profiler and the medium.
  • Page 10 (p. 7) is an example configuration with three external sensors and five internal sensors. Each profiler is custom built to the user’s specific requirements. FIGURE 7-2 (p. 7) shows the label for the first and last internal sensor locations. FIGURE 7-2. Internal sensor label CS230/CS231 Temperature Profilers...

  • Page 11: Mounting

    Orient the signal and power cable of the CS230/CS231 towards the data logger to avoid loops or strain on the cable. Also use a suitable trench or conduit to protect the signal and power cable from damage.

  • Page 12: Programming

    SDI12Recorder() instruction is used to measure the temperature sensors in the CS230/CS231. This instruction sends a request to the sensor to make a measurement and then retrieves the measurement from the sensor. See Sensor measurements (p. 10) for more information.

  • Page 13: Operation

    SDI-12 protocol. Outputs of both lifetime and user resettable minimum and maximum temperatures are also available during powered operation from each temperature point in the CS230/CS231. The user- resettable minimum and maximum temperatures can be used to monitor specific seasons or periods of measure, without having to review the entire data set.

  • Page 14: Sdi-12 Addressing

    If multiple SDI-12 sensors are connected to the data logger, Campbell Scientific recommends using separate terminals when possible. However, multiple SDI-12 sensors or multiple CS230/CS231 sensors can connect to the same data logger control or U terminal if they have different SDI-12 addresses. If changing the SDI-12 addresses, Campbell Scientific recommends starting the readdressing process with the largest temperature sensor address to avoid duplicate addresses.

  • Page 16: Metadata

    The original SDI-12 standard specifies the maximum total cable length for the cable as being 61 m (200 ft), but we are able to exceed this limit by: CS230/CS231 Temperature Profilers...

  • Page 17: Power Conservation

    U terminals 8.3 Power conservation The CS230/CS231 draws less than 1 mA of current per sensor between polling sessions from its 12 V supply. In many applications, this is minimal compared to overall system power use, so the sensor can be permanently powered to avoid the warm-up period.
  • Page 18 Use the aA{! command, where a is the affected address. This will reset the affected sensors to their factory configured address value. For example, if two sensors have address 2, sending 2A{! will reset both sensors to the original addresses. CS230/CS231 Temperature Profilers...

    Block. This adds an apostrophe (') to the beginning of each of the highlighted lines, which instructs the data logger compiler to ignore those lines when compiling. The Comment Block feature is demonstrated at about 5:10 in the CRBasic | Features video CS230/CS231 Temperature Profilers...

  • Page 20: Appendix B. Sdi-12 Sensor Support

    SDI-12, Serial Data Interface at 1200 baud, is a protocol developed to simplify sensor and data logger compatibility. Only three wires are necessary — serial data, ground, and 12 V. With unique addresses, multiple SDI-12 sensors can connect to a single SDI-12 terminal on a Campbell Scientific data logger.
