    Step 1 — Mount Sensor to an Enclosure Backplate The mounting holes for the sensor are one-inch-centered (three inches apart), and will mount directly onto the holes on the backplates of the Campbell Scientific enclosures. Mount the sensor with the pneumatic connector pointing...

  • Page 8: Step 2 - Use Scwin Short Cut To Program Datalogger And Generate Wiring Diagram

    Generate Wiring Diagram The simplest method for programming the datalogger to measure the CS100 is to use Campbell Scientific's SCWin Short Cut Program Generator. 1. Open Short Cut and click on New Program. 2. Select a datalogger and scan interval.

Remove the yellow warning label from the pigtails and wire according to the wiring diagram generated by SCWin Short Cut. WARNING Improper wiring may damage the CS100 beyond repair. Overview The CS100 is a capacitive pressure transducer that uses the Setra's electrical capacitor technology for barometric pressure measurements over the 600 to...

    Setra’s custom Application Specific Integrated Circuit (ASIC). The analog signal generated by the barometer can be directly measured by a Campbell Scientific datalogger. The CS100 is supplied in the triggered mode, in which the datalogger switches 12 VDC power to the barometer before the measurement.

  • Page 14: Installation

    Failure to protect the sensor from condensation may result in permanent damage. The CS100 is typically mounted in a Campbell Scientific enclosure next to the datalogger. Campbell Scientific also offers the ENC100 for situations where it is desirable to house the CS100 in its own enclosure. The ENC100 is a 6.7-in.

  • Page 15: Wiring

    CS100 Barometric Pressure Sensor 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. NOTE For user-supplied enclosures, it may be necessary to make a vent hole on the outer wall.

  • Page 17: Programming

    CS100 Barometric Pressure Sensor Programming The CS100 sensor is measured using the singled-ended voltage measurement instruction (VoltSE() in CRBasic and Instruction 1 in Edlog). Atmospheric pressure changes little with time. In most weather station applications measuring pressure once an hour is adequate. 7.3.1 Conversion Factors In the example programs, the pressure is reported in millibars (mb).

In the example, the CR10X datalogger turns on the CS100 one minute before the top of the hour using a control port.

  • Page 21: Output Resolution

    The default resolution (low resolution) for Campbell Scientific dataloggers is limited to a maximum of four digits. Even then, the maximum digit value that can be displayed is 6999 for Edlog dataloggers, and 7999 for the CRBasic dataloggers.

  • Page 22: Maintenance And Calibration

    The external case can be cleaned with a damp, lint-free cloth and a mild detergent solution. Contact Campbell Scientific, Inc. (435-227-9000) for an RMA number before returning the sensor for recalibration. You may also return the unit directly to Setra for recalibration.
