Types et nombre de capteurs de température

There are a thousand and one reasons to measure temperature. You can prevent a fever by taking body temperature, save energy by controlling the room temperature. You can improvise as a chef with a cooking probe for a perfect Christmas turkey. However, all thermometers have a very distinct use. A barometer for the ambient air, a hygrometer for the humidity level, a recorder for scientific research; there is something for all professions. These measuring instruments also have different functions. Depending on the type and model of thermometer there may be one or several sensors. Some sensors use multiple sensors to improve accuracy and measuring range.

Experts in temperature taking Thermometre.fr come back for you on the different types and number of sensors to help you choose your equipment.

Thermometer sensors called thermocouple

THE thermocouples are one of the most used temperature sensors in different trades. Their high precision, versatility and affordable price make thermocouples an ideal measuring tool.

And thermocouple is a temperature sensing device that consists of two different metals that are joined to form a junction. When the temperature changes at the junction, an electrical voltage is generated. This can be measured and used to determine the temperature.

The main advantage of thermocouples: their versatility.

You can use these thermometers in a wide range of temperatures, from sub-zero to over 2000°C. They are available in different shapes and sizes, making them suitable for many different applications. Thermocouples are relatively inexpensive compared to other types of temperature sensors.

Thermistor thermometer sensors

THE thermistances are small, compact and highly accurate temperature sensors that are widely used in many fields of activity. We are thinking in particular of the processing of food products in industry, in the kitchen, as well as in laboratory cold rooms. Unlike thermocouples, thermistors work by exploiting the relationship between the strength of a material and its temperature.

The main advantage of thermistors: their precision.

Thermistor thermometers provide high-resolution temperature measurement. Digital thermometers are ideal for applications that require precise temperature control. Moreover, thermistors are relatively small and compact, making them very convenient for use in limited spaces. Thanks to their temperature probe, you can also reach hard-to-reach surfaces.

Resistance temperature sensors

THE resistance temperature detectors (also called RTDs) are temperature sensors used more in industrial and commercial applications. Indeed, its high-end functions offer reliable temperature measurements. How do they work? RTDs measure the electrical resistance of a material, usually made of a metal like platinum, which changes with temperature.

The main advantages of resistance thermometers: their high precision, their stability and their versatility.

While these qualities make them an ideal choice in the many cases where precise temperature control is required, they are relatively expensive compared to other types of temperature sensors. Additionally, their limited temperature range may make them less suitable for use in extreme temperatures.

Digital thermometer sensors

THE digital temperature sensors are a type of temperature taking device that provides an electrical output proportional to temperature changes. You can find them in every office and industry today. From industrial processes, to HVAC systems, to medical practices and consumer electronics. All professionals use them.

The main advantage of digital thermometers: their speed.

Unlike analog or mercury temperature sensors, digital temperature sensors are very practical. Direct reading on LCD screen, quick tip change, and programming of an alert: this is only the beginning of its practical features ! They give you the possibility of transmitting the collected measurement data to a PC or smartphone. Also, these little technological jewels are relatively inexpensive compared to other types of temperature sensors.

A digital thermometer may use a thermistor, RTD, thermocouple, or i-circuit digital temperature sensornintegrated. The nThe number of sensors depends on the type and application of the digital thermometer.

How to choose your temperature sensor?

To choose wisely your professional thermometer, it is necessary to know the precise use you will have of it subsequently. This way, you will be able to know if you need a thermometer with contact or sans contact, wireless or wired, etc. You might prefer a thermometer with probe also. You can first find out about the Thermometre.fr Mag' to find out more about these everyday thermometers. However, we recommend that you contact an advisor directly in taking your temperature to guide you in the purchase of your thermometer. If you have any doubt about the type of sensor suitable for your activity, it makes more sense.
