技术说明
CS106使用Vaisala的BAROCAP硅电容传感器来测量大气压力。封装在塑料壳（ABS/PC 混合）内，配有进气阀来平衡压力。
CS106输出0 至 2.5 Vdc的线性信号，因而CS106可以直接地连接到Campbell Scientific数据采集器。内部的切换电路，可以让数据采集器仅在测量时给大气压传感器供电，减小了电源消耗。

Additional Compatibility Information
Data Logger Considerations
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.
Mounting
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.

常见问题解答

-
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.
-
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.
-
Generally, these sensors are designed to measure the pressure of the environment where they are installed. The CS100 or CS106 can measure the air pressure within a snowpack if the enclosure is adequately sealed away from the snow while allowing the vent to have access to the snow. Note that it may be difficult to accomplish this.
-
Yes, but only if certain conditions are met:
- The sensor resides in a non-condensing environment.
- The vent tube accessing the high humidity environment is extremely well desiccated to keep any moisture from reaching the sensor’s components. Moisture in the sensor will damage the sensor, often to an un-repairable state.
-
Noisy measurements may be caused by several factors:
- The sensor was not allowed to warm up adequately.
- The sensor is placed in an electrically noisy environment, which makes other analog measurements noisy.
- The power supply for the sensor or station is dirty. (There is not a clean regulated voltage.)
-
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.
-
Either the CS100 or the CS106 can fit inside an ENC100. For more information, refer to the Specifications information on the ENC100 product page.
-
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.
-
The manufacturer recommends calibration on a yearly basis. However, conformance to published standards or regulations may require this on a more frequent basis.
