Page 11: Introduction
Two variants of the sensor are available, the IR100 has an ultra-narrow field of view whilst the IR120 has a narrow field of view (see specifications below). -

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). -
Page 15: A Cross-Sectional Diagram Of The Sensor Fitted Inside The Ir-Ss Shield
User Manual the sensor above the hole in the sensor nearest the cable (position A) so you can see the mounting hole through the centre of the pillar. Carefully lift the sensor and insert it inside the shield balancing the pillar on sensor as you do so. -

IR100/IR120 Infra-red Remote Temperature Sensor Figure 3. The shield fitted onto the IR1X0 mounting arm Optional band-clamp, pole mounts are available to allow the IR-SS to be mounted on the side of lamp posts and similar structures. The band-clamps are specified to match a specific range of size of pole. -

User Manual free at the end. 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. -
Page 18: Principles Of Measurement
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. -

6.3 Non-Blackbody Infrared Temperature Measurement The following example shows the additional line of code required to obtain an infrared temperature measurement from the IR100 sensor, corrected for a target surface emissivity of 0.94. and assuming that the adjacent surfaces are at the sensor temperature: Emissivity = 0.94... -
