  • Page 13: Overview

    As the temperature of the PV module increases, its output decreases. The 110PV-L consists of a thermistor encased in an aluminium disk (see FIGURE 5-1). The aluminium disk protects the thermistor and promotes heat transfer from surfaces. An adhesive tab on the probe’s aluminium disk fastens the 110PV to the measurement surface.

    PV module does not have distinctive solar cells, center the 110PV on the back of the PV module. If the module has several distinctive photocells, center the 110PV on the back of the photocell that is the middle of the PV module.
  • Page 16: Mounting To A Pv Module Or Other Device

    FIGURE 7-1. Types of PV modules Mounting to a PV Module or Other Device The 110PV includes an adhesive mounting strip adhered to the flat surface of the aluminium disk. To mount the 110PV, remove the paper from the mounting strip and adhere it to the back of the PV module or other device.
  • Page 17: Cable Strain Relief

    The 110PV’s cable must be properly strain relieved after mounting the probe to the measurement surface. To accomplish this, the probe comes with cable ties and a cable tie mount. A yellow label on the 110PV’s cable indicates where the cable should be tied down (see FIGURE 7-3).
  • Page 18: Wiring

    Short Cut. Connections to Campbell Scientific dataloggers are given in TABLE 7-1. Most CRBasic dataloggers can measure the 110PV using either a 4-wire half bridge or 3-wire half bridge. The CR200(X) dataloggers can only use a 3-wire half bridge.
  • Page 19: Resistance Measurement

    7.5.1 Resistance Measurement The CR300 series, CR6, CR800, CR850, CR1000, CR1000X, CR3000, CR5000, and CR9000(X) can use either the BrHalf4W() instruction or BrHalf() instruction to measure the 110PV. The BrHalf4W() instruction reduces cable errors, but the BrHalf() instruction requires fewer input channels.
  • Page 20: Operation

    AC power lines, pumps, and motors, can be the source of electrical noise. If the 110PV probe or datalogger is located in an electrically noisy environment, the 110PV probe should be measured with the 60 or 50 Hz rejection option as shown in Appendix B.1.1, Half Bridge CR1000 Program , and Appendix (p.

    (p. 8) damage and possible moisture intrusion. CAUTION If the 110PV needs to be sent to Campbell Scientific for repairs, remember that the probe must be heated to 70 to 80 °C before removing it from the measurement surface. Prying the probe off without heating it will likely damage both the probe and the PV module.
