They usually work in the range of -50 to 250 °C. Since sometimes the temperature of the liquid/solid is way too high or way to low and then its hard to make contact with it and read its temperature then in that scenario we will need a temperature sensor which can tell the temperature without even touching the object and that kind of temperature sensor / Thermometer is called as non contact Thermometer. To accommodate the variety of instruments, they provide an effective aperture of ~ 1 in. Because the sensor is not necessarily exposed to the same temperature that it is measuring, it can read a wide range of temperatures. A thermocouple is a type of temperature sensor which is used to measure the internal temperature of an object. Advanced optical and electronic signal processing modules greatly extend the accuracy and performance capabilities of noncontact temperature measuring. Field of View. Pressure Transducers  |   Reset is triggered by an external signal. A thermocouple (T/C) is made from two dissimilar metals that generate an electrical voltage in direct proportion with the change in temperature. The spectrum is frequently divided into "atmospheric windows" that provide maximum loss-free transmission through water vapor in air: 0.7-1.3 um; 1.4-1.8 um; 2.0-2.5 um; 3.2-4.3 um; 4.8-5.3 um; 8-14 um Emissivity is determined in part by the type of material and its surface condition, and may vary from close to zero (for a highly reflective mirror) to almost 1 (for a blackbody simulator). Such temperature sensors fall under the category contact-type. The temperature change is directly proportional to the diode’s resistance. Usually, temperature sensors have a wide range of applications, geotechnical monitoring field, being one of them. Here we are going to tell you what is a temperature sensor, how does it work, where is it used, and what are its different types. The oldest brightness pyrometers compared optical brightness in the visible (red) spectrum at 0.65 um by matching the glowing object to a hot "disappearing" filament. The low- and high-temperature versions differ in performance, as shown in Table 2. The resistance element is housed in a closed-end robust stainless steel tubing which protects the element against moisture. pH meter  |   Hence, wires made up of distinct materials are needed. Thermowell  |   Integrated Circuit Sensors  |   Small Targets. A simple temperature sensor is a device, to measure the temperature through an electrical signal it requires a thermocouple or RTD (Resistance Temperature Detectors).
