    (ABS/PC blend) fitted with an intake port for pressure equalization. The CS106 outputs a linear 0 to 2.5 Vdc signal that corresponds to 500 to 1100 mb. It can be operated in a shutdown or normal mode (see Section 7.1, Jumper Settings).

    CS106 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 CS106 is in normal mode and powered continuously.

    Campbell Scientific also offers the ENC100 for situations where it is desirable to house the CS106 in its own enclosure (see Figure 7-2). The ENC100 is a 17 cm (6.7 in) x 13.9 cm (5.5 in) x 9.3 cm (3.7 in) enclosure that includes a...

    User Manual Figure 7-2. ENC100 is a very small enclosure that can house one CS106 Remember that for the sensor to detect the external ambient pressure, the enclosure must vent to the atmosphere (i.e., not be “hermetically sealed”). Enclosures purchased from Campbell Scientific properly vent to the atmosphere.

    This connector is removable and may be replaced. The replacement connector may come with a connector key attached to it to ensure that the connector is plugged into the CS106 right side up (see Figure 7-4). When the connector is right side up, it will easily plug into the barometer.

    In most weather station applications, measuring the barometer pressure once an hour is adequate. See Appendix B, Example Programs, for more information. 7.4.2 Edlog Instructions The Volt (SE) (P1) measurement instruction programs Edlog dataloggers (CR500, CR510, CR10(X), CR23X, CR7, and 21X) to measure the CS106.

    User Manual Volt (SE) (P1) Reps 2500 mV 60 Hz Rejection Range SE Channel Loc [ CS106 0.240 Multiplier Offset At sea level, a multiplier of 0.24 and an offset of 500 will report the barometric pressure in mbar or hPa. The offset will need to be adjusted if the barometer is not at sea level (see Section 8.5, Correcting Pressure to Sea Level).

  • Page 22: Long Lead Lengths

    Torr 0.75006 Long Lead Lengths There is a 0.06 mV/foot voltage drop in the CS106 signal leads. This voltage drop, in long lead lengths, will raise the barometric reading by approximately 1.44 mb per 100 feet. For lead lengths greater than 20 feet, use the differential instruction (VoltDiff() in CRBasic or Volt (DIFF) (P2) in Edlog) to measure the CS106.

  • Page 23: Maintenance And Calibration

    Vaisala recommends recalibration every two years under normal use. In areas where a lot of contaminants are present, recalibration every year is recommended. Contact Campbell Scientific Ltd for an RMA number before returning the sensor for recalibration. Should you lose the five terminal connector (pn #16004), the replacement part can be purchased from Campbell Scientific Ltd.

    Appendix A. Importing Short Cut Code Into CRBasic Editor Import wiring information to the program by opening the associated .DEF file. Copy and paste the section beginning with heading “-Wiring for CRXXX–” into the CRBasic program, usually at the head of the file. After pasting, edit the information such that a ' character (single quotation mark) begins each line.

  • Page 27: Example Programs

    In the example, the CR1000 measures the CS106 once an hour. To do this, the CR1000 uses a control port to turn on the CS106 one minute before the top of the hour. On the hour, the datalogger measures the CS106, and then turns the CS106 off.

  • Page 28: Example Cr1000 Program Using Pipeline Mode

    Although this example is for the CR1000, other CRBasic dataloggers, such as the CR6, CR200(X), CR800, CR850, CR3000, and CR9000(X) are programmed similarly. In the example, the CR1000 measures the CS106 once an hour in a program that runs at 1 Hz. In order to keep the CR1000 running in a pipeline mode, the measurement instruction is placed outside the “If”...

    CR510, CR23X, 21X, and CR7, are programmed similarly. In the example, the CR10X turns on the CS106 one minute before the top of the hour using a control port. On the hour the datalogger measures the CS106, and then it turns the CS106 off.
