Dây cảm biến đo nhiệt độ đa điểm kết nối SDI-12 Campbell Scientific CS225-L

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 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 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 is custom manufactured.

Temperature profiling with the CS225 is suited for a wide variety of applications and environments, including boreholes, soils, water, frost, and permafrost monitoring.

Detailed Description

The CS225-L consists of an arrangement of temperature sensors mounted in rugged steel-reinforced cable. Temperature points are over-molded to provide long-term protection in all mediums. Each CS225-L is manufactured to the client’s specific requirements.

The CS225-L is suited for a wide variety of applications and environments that require temperature profiling.

The assembly is completely sealed, which means that the CS225-L can be submerged, buried, or even incorporated directly within structures. Application examples of temperature profiling include boreholes, soils, water, frost, and permafrost.

The physical and electrical integrity of the CS225-L were rigorously tested during development to ensure it can withstand bending, pulling, pressure, freeze/thaw cycles, and temperature cycles.

When power is supplied to the CS225-L 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.
