The most commonly measured physical parameter is temperature whether in process industry applications or in laboratory settings. Exact measurements are critical part of success. Exact measurements are needed for many applications such as medical applications, materials research in labs, studies of electronic or electrical components, biological research, and geological studies. There are different types of temperature sensors used in the market today including resistance temperature detectors RTDs , thermocouples, thermistors, infrared sensor , and semiconductor sensors. Each of them has a particular operating parameters.
The four most common types of temperature sensors, ranging in responsiveness and accuracy from high to low are:. A thermistor is a thermally sensitive resistor that exhibits a continuous, small, incremental change in resistance correlated to variations in temperature. An NTC thermistor provides higher resistance at low temperatures. As temperature increases, the resistance drops incrementally, according to its R-T table. The output of an NTC thermistor is non-linear due to its exponential nature; however, it can be linearized based on its application. An RTD consists of a film or, for greater accuracy, a wire wrapped around a ceramic or glass core.
Ed Edwards. The term temperature sensor refers to a class of devices that provide a measurement of the temperature of objects, and either display a reading directly or produce an output signal whose value can be translated into a temperature reading. Temperature is a fundamental measurement of thermal energy and can be thought of as a measure of the average kinetic energy of the atoms and molecules of a material. There are several types of temperature sensors used in industrial applications. This article will review the different types of temperature sensors and provide information on how they function and their applications. The majority of these the exception being infrared temperature sensors are contact sensors, meaning that the sensor or probe must physically contact the object whose temperature is being measured in order to take a reading.
We all use temperature sensors in our daily lives, be it in the form of thermometers, domestic water heaters, microwaves, or refrigerators. Usually, temperature sensors have a wide range of applications, geotechnical monitoring field, being one of them. Temperature sensors are a simple instrument that measures the degree of hotness or coolness and converts it into a readable unit. But, have you ever wondered how the temperature of the soil, boreholes, huge concrete dams or buildings is measured? Well, this is accomplished through some of the specialised temperature sensors. Temperature sensors are designed to keep a regular check on concrete structures, bridges, railway tracks, soil, etc. 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.

Temperature is the most often-measured environmental quantity. This might be expected since most physical, electronic, chemical, mechanical, and biological systems are affected by temperature. Certain chemical reactions, biological processes, and even electronic circuits perform best within limited temperature ranges. Temperature is one of the most commonly measured variables and it is therefore not surprising that there are many ways of sensing it. Temperature sensing can be done either through direct contact with the heating source or remotely, without direct contact with the source using radiated energy instead.

Temperature is defined as the energy level of matter which can be evidenced by some change in that matter. Temperature measuring sensors come in a wide variety and have one thing in common: they all measure temperature by sensing some change in a physical characteristic. Thermocouples are voltage devices that indicate temperature measurement with a change in voltage.
There are many applications where maintaining a specific temperature is vital, for example, if products must be kept at a certain temperature or for patient monitoring, the responsiveness and accuracy of the temperature sensor is critical. More frequently temperature sensor applications will also incorporate instances where although the temperature is not the forefront of the process, other components may not be able to function at certain temperatures so the temperature must be monitored within the application for this reason. The temperature sensor will indicate when the environment becomes too hot or cold and preventative action can be taken to ensure that the entire device is not compromised. There are Temperature Sensor applications in many industries including medical, motorsport, HVAC, agriculture, industrial, aerospace and automotive. Here are some of the specific temperature sensor applications which we have come across. Here at Variohm, we are pleased to offer a complete range of temperature sensors from our trusted suppliers as well as our own manufactured products. All of our temperature sensors can be seen here.
Он терпеть не мог эти ярусы. Он был там только один раз, когда проходил подготовку. Этот враждебный мир заполняли рабочие мостки, фреоновые трубки и пропасть глубиной 136 футов, на дне которой располагались генераторы питания ТРАНСТЕКСТА… Чатрукьяну страшно не хотелось погружаться в этот мир, да и вставать на пути Стратмора было далеко не безопасно, но долг есть долг. Завтра они скажут мне спасибо, - подумал он, так и не решив, правильно ли поступает. Набрав полные легкие воздуха, Чатрукьян открыл металлический шкафчик старшего сотрудника лаборатории систем безопасности.
Все трое как завороженные смотрели на это зрелище, не лишенное какой-то потусторонней величественности. Фонтейн словно окаменел. Когда же он пришел в себя, его голос был едва слышен, но исполнен решимости: - Мидж, вызовите аварийную команду.
