The simplest resistance-thermometer configuration uses two wires. It is only used when high accuracy is not required, as the resistance of the connecting wires is added to that of the sensor, leading to errors of measurement. This configuration allows use of 100 meters of cable. This applies equally to balanced bridge and fixed bridge system.
Polymers represent another large area in which thermal analysis finds strong applications. Thermoplastic polymers are commonly found in everyday packaging and household items, but for the analysis of the raw materials, effects of the many additive used (including stabilisers and colours) and fine-tuning of the moulding or extrusion processing used can be achieved by using differential scanning ...
FHF04SC is a self-calibrating version of the flexible FHF04 heat flux sensor. Sensors that are embedded in construction can sometimes be very troublesome to remove if they need to be re-calibrated (in a lab). Some sensors incorporate heaters in order to be able to leave the sensor in place while performing a re-calibration.
Figure 2: [8] Working principle of a thermal laser sensor (Adapted from figure 3 with permission) As shown in Fig 2, a thermopile laser sensor consists of several thermocouples connected in series with one junction type (hot junction at temperature T 1) being exposed to an absorption area and the other junction type (cold junction at temperature T 2) being exposed to a heat sink.
The 2000s have witnessed the rapid development of Fast-scan DSC (FSC), [11] a novel calorimetric technique that employs micromachined sensors. The key advances of this technique are the ultrahigh scanning rate, which can be as high as 10 6 K/s, and the ultrahigh sensitivity, with a heat capacity resolution typically better than 1 nJ/K.

A properly designed experimental program is the most reliable way of determining the viability of a thermometric titration approach. Successful applications for thermometric titrations are generally where titrant-titrand reaction kinetics are fast, and chemical equilibria are stoichiometric or nearly so.
Dielectric thermal analysis (DETA), or dielectric analysis (DEA), is a materials science technique similar to dynamic mechanical analysis except that an oscillating electrical field is used instead of a mechanical force. [1]
ThermoSensor is a coin-sized battery-powered RFID-enabled temperature sensor which is to be attached to the lower abdomen of patients by using 3M Tegaderm for body temperature monitoring. ThermoSensor was invented by the company Cadi Scientific in 2003 in Singapore for body temperature monitoring but it was later used for location tracking of ...
