The CS106, manufactured by Vaisala, measures barometric pressure for the range of 500 to 1100 hPa (mBar). This range equates to from below sea level (as in a mine) to over 15,000 feet above sea level. Designed for use in environmental applications, the CS106 is compatible with most Campbell Scientific data loggers. The CS106 has an attached 76.2 cm (30 in.) cable.Read More

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
A 2.5-ft cable is supplied with the sensor for connection to the data logger. The cable connects to a control port, single-ended analog input terminal, 12 V power terminal, and ground terminal on the data logger.
The CS106 is typically mounted next to the data logger inside an ENC12/14 or larger enclosure. The very small ENC100 is available for housing the CS106 separately, in its own enclosure.

The sensor plug on the CS106 is the same as the one on the CS105. If the cable and connections are still working correctly, it should be possible to power down the station and swap out the sensors without any difficulty.
The CS106 is not a direct replacement. To use a CS106 in a system that previously used a CS105, the multiplier and offset will need to be changed in the program. Because the CS106 has a longer warm-up time, if the sensor is turned on and off, it may be necessary to make some adjustments to the warm-up time.
Noisy measurements may be caused by several factors:
Yes, but only if certain conditions are met:
Either the CS100 or the CS106 can fit inside an ENC100. For more information, refer to the Specifications information on the ENC100 product page.
In most cases, enclosures and buildings have enough little spaces for the pressure to stay at equilibrium with the outside pressure. Therefore, the sensor does not need to be vented to the outside. It is possible, however, that the rate at which the pressure equalizes is slowed by being in an enclosure, but the rate change usually is not noticeably significant.
If the sensor resides in an absolutely air-tight environment, and the pressure outside this environment needs to be measured, then the sensor will need to be vented to the outside. However, venting to the outside may change the rating of the enclosure or associated inside environment.
The manufacturer recommends calibration on a yearly basis. However, conformance to published standards or regulations may require this on a more frequent basis.
For a reading in millibars, the multiplier is 0.240, and the offset is 500. To convert the millibar reading to different units, add an equation to the code.
To correct the pressure to sea level, see the “Correcting Pressure to Sea Level” section in the CS100 instruction manual or in the CS106 instruction manual. Alternatively, use Short Cut for Windows to generate the program, and, when prompted, enter the appropriate site elevation.
A CS106 Barometric Pressure Sensor can be added to the station. However, the sensor needs to be wired into the wiring terminal inside the enclosure, and the data logger program needs to be edited to include the instructions to poll the sensor and store the values.
Note: Some versions of the ET107 station that are interfaced with irrigation companies may have proprietary programs or complicated programs that are not easily changed.
