There are a thousand and one reasons for measure the temperature. You can prevent fever by taking body temperature, saving energy by controlling room temperature. You can improvise chef with a cooking probe for a perfect Christmas turkey. Only here, all thermometers have a very distinct utility. A barometer For the ambient air, a hygrometer For the humidity, a recorder for scientific research; There is something for all trades. These measurement instruments also have different functions. Depending on the type and thermometer model there can be only one as several sensors. Some sensors use several sensors to improve precision and measurement range.
Experts in temperature of Thermometre.fr come back for you on different types and number of sensors To guide you in the choice of your equipment.
The thermometers so -called Thermocouple
THE thermocouples are one of the most used temperature sensors in different trades. Their great precision, their versatility and their affordable price make thermocouples an ideal measurement tool.
A thermocouple is a temperature detection device that consists of two different metals which are attached to form a junction. When the temperature changes at the junction, an electrical voltage is generated. You can measure and use this to determine the temperature.
The main advantage of thermocouples: their versatility.
You can use these thermometers in a wide range of temperatures, ranging from zero to more than 2000 ° C. They are available in different forms and sizes, which makes them suitable for many different applications. Thermocouples are relatively inexpensive compared to other types of temperature sensors.
Thermometers with thermistor
THE thermist are small, compact and very precise temperature sensors that are widely used in many areas of activity. We think in particular of the treatments of food products in industry, in the kitchen, as well as in the cold rooms of the laboratories. Unlike thermocouples, Thermists work by exploiting the relationship between the resistance of a material and its temperature.
The main advantage of thermists: their precision.
Thermistor thermometers provide a high resolution temperature measurement. Digital thermometers are ideal for applications that require precise temperature control. Moreover, Thermists are relatively small and compact, which makes them very practical for use in limited spaces. Thanks to their temperature probe, you can also reach difficult to access surfaces.
Resistance temperature sensors
THE resistance temperature detectors (also called RTD) are more used temperature sensors in industrial and commercial applications. Indeed, its high -end functions offer reliable temperature measures. How do they work? RTD Measure the electrical resistance of a material, generally made up of a metal such as platinum, which changes with temperature.
The main advantages of resistance thermometers: their high precision, their stability and their versatility.
If these qualities make it an ideal choice in the many cases where precise temperature control is required, they are relatively expensive compared to other types of temperature sensors. In addition, their limited temperature range can make them less suitable for use at extreme temperatures.
Digital thermometers
THE digital temperature sensors are a type of temperature intake device that provides an electrical output proportional to temperature changes. You can find them in all offices and industries today. From industrial processes to CVC systems, including medical firms and consumer electronics. All professionals use it.
The main advantage of digital thermometers: their speed.
Unlike analog temperature sensors or mercury, digital temperature sensors are very practical. Direct reading on LCD screen, quick change of tips, and programming an alert: this is only the beginning of its practical functionalities ! They give you the possibility of transmitting the measurement data collected to a PC or a smartphone. Also, these little technological jewels are relatively inexpensive compared to other types of temperature sensors.
A digital thermometer can use thermistor, RTD, thermocouple or a digital temperature sensor with circuit intégré. The NShadow of sensors depends on the type and application of the digital thermometer.
How to choose your temperature sensor?
To choose the right Your professional thermometer, it is necessary to know the precise use that you will have later. So you will be able to know if you need A thermometer with contact Or contactless, wireless or with wire, etc. You might prefer a Thermometer with probe also. You can first inquire about the Mag ’Thermometre.fr to find out more about these daily thermometers. However, we recommend that you contact an advisor directly Taking temperature to orient yourself in the purchase of your thermometer. If you have a doubt about the type of sensor adapted to your activity, it is more judicious.
