This product is no longer available and has been replaced by: CS106. Some accessories, replacement parts, or services may still be available.


The CS105 measured barometric pressure for the range of 600 to 1060 mb (approximately sea level to 12,000 feet). A 12 V switching circuit was included in the sensor; a datalogger control port was used to control 12 Vdc power to the sensor, reducing power consumption. A sensor warm-up time of up to 1 second was recommended.



Accuracy ±0.5 mb (@ +20°C)
Temperature Range -40° to +60°C
Dimensions 6.1 x 6.1 x 2.0 cm ( 2.4 x 2.4 x 0.8 in.)


Datalogger Considerations

A 2.5-ft cable is supplied with the sensor for connection to the datalogger. The cable connects to a control port, single-ended analog input terminal, 12 V power terminal, and ground terminal on the datalogger.

The CS105 is typically mounted next to the datalogger inside an ENC12/14 or larger enclosure. The very small ENC100 is available for housing the CS105 separately, in its own enclosure.
