CS105/CS105MD Barometric Pressure Sensor

Supply Voltage: 10 to 30 VDC

Supply Voltage Control: When enabled with an internal jumper, the CS105 is

on continually. When disabled, the CS105 can be turned on/off with 5 VDC/0

VDC.

Supply voltage sensitivity: Less than 0.1 mb

Current Consumption: <4 mA (active); <1

µA (quiescent)

Output Voltage: 0 to 2.5 VDC

Warm Up Time: 1 second

Pressure fitting: barbed fitting for 1/8” I.D. tubing

Overpressure limit: 2000 mb

The black outer jacket of the cable is Santoprene

rubber. This

compound was chosen for its resistance to temperature extremes,

moisture, and UV degradation. However, this jacket will

support combustion in air. It is rated as slow burning when

tested according to U.L. 94 H.B. and will pass FMVSS302.

Local fire codes may preclude its use inside buildings.

NOTE

3. Installation and Wiring

The CS105 can be operated in one of two modes: powerup and continuous.

The mode is selected by a jumper located underneath a black plug on the face

of the barometer. When the jumper is not installed, the CS105 is in powerup

mode and the datalogger turns the CS105 on and off with a control port or

excitation channel; to use the excitation channel the datalogger must be able to

provide an excitation voltage of 5 VDC. When the jumper is installed the

CS105 is powered continuously.

CS105s shipped from Campbell Scientific are configured for

powerup mode (jumper open).

NOTE

CS105MDs shipped from Campbell Scientific are configured for

continuous power mode (jumper closed).

NOTE

Mount the CS105 to the backplate in the same enclosure that the datalogger is

located in (Figures 1 and 2).

On the older (grey jacketed) cable pressure (VOUT) was brown

and signal ground (AGND) was white.
