e (= CS225 SDI-12 Temperature Sensor String CAMPBELL SCIENTIFIC MATTER I5 N WHEN MEASUREMENTS Overview The CS225 is a prime example of our commitment to provide the highest-quality monitoring products in the world. Our revamped design, rigorous validation process, and stringent quality standards are all focused on providing the fantastic quality you require to reliably generate data you can trust, even in the harshest of environments. Learn more about the C5225's quality testing and validation process. The C5225 temperature string uses multi-point temperature profiles and SDI-12 digital technology for simple integration and reliability. The C5225 consists of an arrangement of temperature sensors mounted in rugged steel-reinforced cable, permitting it to be buried, submerged, or integrated directly into structures. Temperature points are over-molded to provide long-term protection in all mediums. Each C5225 is custom manufactured. Benefits and Features ) One SDI-12 channel is used to connect all temperature sensors ) Low power—suitable for remote applications ) No calibration required Rugged Construction Digital temperature measurements Temperature profiling with the CS225 is suited for a wide variety of applications and environments, including the following: ) Borehole temperature profiling and borehole ground measurement ) Measuring geothermal heat gradient ) Lake stratification and thermal stratification measurement ) Soil temperature profiles ) Water temperature profiling ) Frost heave monitoring ) Active layer thickness permafrost monitoring and permafrost depth measurement ) Talik ground temperature ) Heat flow measurement ) Comprehensive measurement range ) Makes use of the included SGB3 to protect against electrical surges ) Extremely rugged and thoroughly tested For comprehensive details, visit: www.campbellsci.eu/cs225 ‘
Rigorous Quality Testing of the CS225 Temperature String We know clients need a really tough temperature string. These strings will be pulled through conduit, buried under concrete, frozen underground, and submersed in water, so quality is of the utmost importance. We put the C5225 through various tests to ensure it can withstand bending, pulling, pressure, freeze/thaw cycles, and temperature cycles. This series of tests confirmed the physical and electrical integrity of the C5225. When power is supplied to the CS225 probe, the internal electronics will continuously measure the temperature at an approximate rate of 1 measurement per second. Every output measurement obtained from the sensor is a running average of 10 consecutive 1-second readings. The accuracy specification is based on an average of 10 consecutive readings. For this purpose, after initial power-up, it is recommended to delay 10 seconds to obtain the best accuracy. Because the sensor is obtaining a measurement every 1 second, it is recommended to use the Continuous measurement command to obtain the temperature readings. Using the "R" commands will reduce the time taken to obtain a reading with the SDI-12 protocol.
