Der CS100 misst den barometrischen Luftdruck im Bereich von 600 zu 1100 mbar. Dieser Bereich entspricht von unter dem Meeresspiegel, etwa in einer Mine bis zu etwa 3600 m über dem Meeresspiegel. Der CS100 ist mit allen Datenloggern von Campbell Scientific kompatibel.Lesen Sie mehr
The CS100 is a Campbell Scientific version of Setra's model 278 barometer. It uses Setra’s Setraceram capacitive sensor and IC analog circuit to measure barometric pressure.
The CS100 is encased in a stainless steel and polyester case fitted with an 1/8 in. barbed fitting for pressure connection. It includes an internal switching circuit that allows the datalogger to power the barometer only during measurement, which reduces power consumption.

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 CS100 is typically mounted next to the data logger inside an ENC12/14 or larger enclosure. The very small ENC100 is available for housing the CS100 separately, in its own enclosure.

Yes, but only if certain conditions are met:
Noisy measurements may be caused by several factors:
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.
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.
