Technical Description

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.
