  • Page 14: Installation

    The IR100 sensor should not be allowed to fill with water. Do not point skywards. The IR100 can be secured by means of one or two 6 mm screws to fix the sensor to a flat surface - such as a metal mounting bracket (screws not provided).

The band-clamps are specified to match a specific range of size of pole.

Then screw that bolt into the side of the shield, so the bolt is fully screwed into the metal insert in the shield, but not so far that the end is not touching the body of the sensor. Now mount the bracket on the pole using the band, rotating the band so the sensor points in the right direction.

    The IR100 will also be more sensitive to moisture in the atmosphere compared to the IR120 so the distance to the target should be minimised.

  • Page 19: Correction For Non-Blackbody Surfaces

    (IRcan_Temp -25) 5.4 Correction for Non-Blackbody Surfaces The IR100 sensor is calibrated against a blackbody target. The proportion of energy it emits to that which it reflects is known as its Emissivity (ε). A black body is said to have an emissivity of 1.

  • Page 20: Getting The Best Measurements

    This is because reflection can lead to significant errors and reflection increases the more acute the angle. Those reflections can be long wave IR and/or from reflected sunlight (the IR100 is more prone to this as it has a little sensitivity at lower wavelengths). ...

  • Page 21: Program Examples & Explanation Of Terms

    The following CR1000 program example shows the code required to obtain a raw infrared radiation measurement from the IR-100 sensor. To minimise the effect of noise on the signal the IR100 has an internal amplifier that requires a positive 2500 mV excitation and at least a75 mS settling time before taking the measurement.

  • Page 22: Correcting For An Enclosure Window

    This correction is not needed for the sensor fitted in an IR-SS shield. Campbell Scientific have supplied enclosure with a thin plastic white film that has high IR transmission or an enclosure with a hard germanium window.
