    LoggerNet, PC400, RTDAQ, or PC200W to make sure it is making reasonable measurements. Overview The CS231 offers the same precise temperature profiling as our CS230 SDI-12 Temperature Profiler, but designed for easier use in borehole and road applications. The two profilers have the same programming, wiring, and measurement specifications.

  • Page 14: Specifications

    The CS230/CS231 is suited for a wide variety of applications and environments. The completely sealed probe assembly and external probes permits the CS230/CS231 to be used in roadbeds, soils, and water (snow and ice). Examples of some applications include spring load adjustment, frost and permafrost monitoring, soil and water temperature profiling, and snowpack temperature profiling.

  • Page 15: Installation

    Installation 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 17: 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 18: Sdi12Recorder() Instruction

    7.4.1 SDI12Recorder() Instruction The 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 Section 8.1, Sensor Measurements , for more information.

If changing the SDI-12 addresses, Campbell Scientific recommends starting the readdressing process with the largest temperature sensor address to avoid duplicate addresses. TABLE provides the SDI-12 addresses and positions.

    U terminals 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.

    CS230/CS231 Temperature Profiler Maintenance, Calibration, and Troubleshooting The CS230/CS231 probe requires no maintenance nor calibration. The following are symptoms and possible corrections. Symptom: –9999 or NAN for temperature 1. Verify the green wire is connected to the control port specified by the SDI12 measurement instruction.
