Rugged, digital temperature measurements
概述
CS230温度分析器使用SDI-12数字技术进行简单的集成。SDI-12与模拟测量不准确和对电噪声的易感性进行。CS230包括刚性探头组件，最多四个可选的外部温度探头。刚性探头组件在轮廓内保持温度点的精确位置，同时在长期的所有媒体中保护温度传感器。
The CS230 is suited for a wide variety of applications and environments. The completely sealed probe assembly and external probes permit the CS230 to be used in roadbeds, soils, and water (snow and ice). Applications where the CS230 is used include spring-load adjustment, frost and permafrost monitoring, and soil and water temperature profiling.

Detailed Description
When power is supplied to the CS230 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.

CS230/CS231 Program Examples (4 KB)08-26-2021
Three example programs that measure the temperature sensors on the CS230/CS231 probe. The number of temperature sensors and the SDI-12 control terminal are entered as constants at the beginning of the programs to allow users to easily change them to match their application. The example programs support the CR6 and CR1000X data loggers. Programs for other dataloggers will be similar.
CS231.CRB程序使用SDI-12地址1到9和A到A至F至F的15个传感器。每60秒，AR0！命令轮询每个温度传感器，然后数据存储在表中。其他公共站数据每60秒测量每60秒并存储到每日数据表。
The cs231-slow.CRB program measures 20 temperature sensors with SDI-12 addresses 1 through 9 and A through F. The program uses the SlowSequence instruction and the aR0! command to poll each temperature sensor every 60 seconds. The temperature sensor data is stored to a data table on the same interval. Other common station data is measured every 5 seconds and stored to daily and hourly data tables.
的cs231-metdata.CRB program measures 15 sensors with SDI-12 addresses 1 through 9 and A through F. Each temperature sensor is polled on power up and daily with the aR1! command to determine metadata, which is stored in a daily data table. Other common station data is measured every 60 seconds and stored to a separate daily data table.
