The CS225 Temperature String 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 CS225's quality testing and validation process.
The CS225 temperature string utilizes multi-point temperature profiles and SDI-12 digital technology for simple integration and reliability. The CS225 Temperature String 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 CS225 Temperature String is custom manufactured.
Temperature profiling with the CS225 is suited for a wide variety of applications and environments, including the following:
The CS225 is available with a 1KG stainless steel weight kit designed for use in water profiling or borehole applications. The weight fits over the string’s last temperature node and is secured with a collar. This kit ensures the temperature string remains at the appropriate depth, and can be secured to prevent it from drifting if necessary.
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 CS225 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 CS225.
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.
