    READ AND UNDERSTAND the Safety Although the CS225 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.

  • Page 8: Initial Inspection

    3. Initial inspection Upon receipt of the CS225, inspect the packaging and contents for damage. File damage claims with the shipping company. The model number and cable length are printed on a label at the connection end of the cable. Check this information against the shipping documents to ensure the expected product and cable length were received.

  • Page 12: Overview

    The CS225 Temperature String uses digital sensor technology allowing for a simple three-wire integration. The CS225 consists of an arrangement of over moulded temperature points mounted in a rugged steel reinforced cable. Each CS225 is manufactured to the client’s specific requirements.

    Maximum voltage: ±28 VDC / 20 VAC (L1, L2, L3 with respect to G terminals) Maximum current: 2 A per terminal, 4 A total (requires both ground terminals for return current) Maximum rated surge: 1200 A (8/20 μs) CS225 Temperature String...

  • Page 14: Installation

    (p. 2) for a Short Cut tutorial. 7.1 Siting Install the CS225 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 15: Wiring

    For the CR6 and CR1000X, triggering conflicts may occur when a companion terminal is used for a triggering instruction such as TimerInput(), PulseCount(), or WaitDigTrig(). For example, if the CS225 is connected to C3 on a CR1000X, C4 cannot be used in the TimerInput(), PulseCount(), or WaitDigTrig() instructions.

  • Page 16: Programming

    For example, if a CS225 consists of 17 or more temperature sensors, the time required to poll all sensors and receive data can be greater than 5 seconds based on the 300 ms execution time for the aR0! command.

  • Page 17: Operation

    Table 8-1 (p. 11). When power is supplied to the CS225, the internal electronics continuously measure temperature at a rate of approximately once per second. Every output measurement (aR0! or aM0!) obtained from the sensor is a running average of 10 consecutive readings. The accuracy specification is based on an average of 10 consecutive readings.

  • Page 18: Sdi-12 Addressing

    Each temperature sensor has a different default SDI-12 address. The starting addresses is 1 and coincides with the top temperature point. The last address coincides with the bottom sensor. 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 CS225 sensors can connect to the same data logger control or U terminal if they have different SDI-12 addresses.

    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: CS225 Temperature String...

  • Page 21: Power Conservation

    U terminals 8.3 Power conservation The CS225 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 22 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. CS225 Temperature String...

  • Page 24: 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.
