CS230/CS231 Temperature Profiler 

1. Introduction

The CS230/CS231 temperature profiler provides temperature measurements 

both in a rigid probe assembly and external probes using digital sensor 

technology. It uses the SDI-12 communication protocol to communicate with 

an SDI-12 recorder simplifying installation and programming.  

SGB3 Surge Protectors were  shipped with older CS230 

temperature profilers  (serial numbers < 1162).  Newer  CS230s 

(serial numbers 

  1162)  and all CS231s  include built-in surge 

protection, and therefore do not need the SGB3. For more 

information, refer to  Appendix 

D

SGB3 Electrical Surge 

Protector

 

(p. D-1)

 

2. Precautions

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.

The black outer jacket of the cable is Santoprene® rubber. This compound

was chosen for its resistance to temperature extremes, moisture, and UV

degradation. However, this jacket will support combustion in air. It is rated

as slow burning when tested according to U.L. 94 H.B. and will pass

FMVSS302. Local fire codes may preclude its use inside buildings

3. Initial Inspection

Upon receipt of the CS230/CS231, inspect the packaging and contents for

damage. File any damage claims with the shipping company. Immediately

check package contents against the shipping documentation. Contact

Campbell Scientific about any discrepancies.

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 are received.
