- Page 2 The LAT-C is the sensor part of the measuring system. This means that the LAT-C sensor must be installed onto a leaf of the experimental plant, and connected to a data logger for continuous data recording.
- Page 3 LAT-C Leaf Sensor Never pull the cable from the sensor and avoid any tension between the cable and sensor during handling, set up and operation. Pay attention to connections to data logger. Wrong connections will provide wrong read- ings. 4. Installation 4.1 Required tools...
- Page 4 Campbell Data Logger (CR1000) The LAT-C sensor must be measured in differential voltage mode, measurement range must be set to 7.5 mV. One CR1000 can record 4 LAT-C sensors in differential mode. Differential Voltage Mode ( 3 LAT-C sensors) Connection...
- Page 5 LAT-C Leaf Sensor 6. Data Calculation According to its two electronic components, thermopile and thermistor, the sensor has two analog output signals: Thermopile (Leaf-to-Air temperature difference): Signal ranges within ± 10mV. This range covers temperature differences between the leaf surface and the surrounding air of over ± 20°C. If wired as indicated in section 5., a nega- tive sensor signal indicates a lower, a positive sensor signal a higher leaf surface temper- ature, as compared to air temperature.
- Page 6 In regions with a pronounced winter season, the sensor should be deinstalled before snow fall. 8.
