According to the report of telescope website, we found out that Maniad Sanat Radin Azhand company has acquired technical knowledge in the field of manufacturing temperature sensors such as thermocouple sensor, RTD sensor and NTC sensor, and it supplies its products in all large and small industries.
You are probably right now collecting information on temperature sensors for your machinery. You may know what their function is, but you are still not clear on what types of temperature sensors exist. Knowing the types of temperature sensors will help you to know which is the most appropriate when installing one of these systems in your company.
For this reason, in the following post we are going to solve all your doubts: what types of temperature sensors exist, what are the differences between a thermostat and a temperature sensor and which of these sensors is the most recommended and used at the moment.
Stay with us to solve all these questions. Let's start:
What is a temperature sensor?
Temperature sensors are devices used in building applications to measure the temperature of a fluid, usually air or water. Usually, they are also known by the name of temperature probes.
What types of temperature sensors are there?
The operating principle of temperature sensors can be of many types. The most common sensors in buildings are the following:
Thermocouples Sensor
Thermocouples. They work through a principle of generating a current between two different metals joined together that have different electrical behavior as a function of temperature. The generated signal is processed and results in a temperature measurement. They are simple, cheap equipment with sufficient precision for use in construction. However, they have a slow response.
Correct and correct consultation with expert experts in the field of industrial electricity in the field of buying thermocouples, thermocouples, temperature probes, temperature probes (especially Thermocouple), will help you to buy the most correct temperature measurement sensor. So be sure to contact the professional experts and specialists of Maniad Sanat Radin Azhand before buying temperature probes and accessories. We will help you make the best purchase and be 100% satisfied with your product. It is also important to mention that the quality and brand of the sensor you choose is very, very important. If, God forbid, a mistake is made in this matter, you will have many problems in this field. As with all types of sensors, the best choice of thermocouple for the specific needs of the work you have in mind is largely influenced by the variety of types, temperature ranges intended for measurement, materials, configurations, and costs related to temperature probes available in the Iranian market.
Thermoresistances
They are made up of resistors whose conductivity varies depending on the temperature, which generates a signal that, once processed, allows the temperature measurement to be obtained. Its response speed depends on the mass of the resistor.
Electronic sensors
They work through electronic devices that generate a current or signal depending on the temperature. They are teams with a much faster response, but more expensive.
Temperature sensors measure the dry temperature of the air, therefore, if you want to obtain a measurement of the enthalpy of the air, which takes humidity into account, it must be integrated into a temperature and relative humidity probe. These probes make it possible to determine, by measuring these two parameters, all the other air parameters: dry temperature, absolute humidity and dew point. For this, a psychrometric diagram is used.
RTD Sensors
RTD sensors -an acronym for the English terms Resistance Temperature Detector– are resistance temperature measurement devices.
In a nutshell, the sensor detects and measures any change in temperature thanks to the variation in electrical resistance of a conductive material. The electrical resistance of a material is modified according to a temperature coefficient or thermal coefficient that the material varies.
What materials are RTD sensors made of?
Always, RTD sensors are made of wires made of materials with a positive temperature coefficient, such as copper, nickel or platinum. The latter, platinum, is one of the most used.
What are the advantages of platinum? Basically, it offers great long-term stability. It also resists in perfect conditions without yielding to corrosion and has the ability to detect a temperature range that ranges from -200ºC to over 800ºC positive. The PT1000 or PT100 specimens are known (More information in the blog post “PT100 temperature sensor”).
When the expected temperatures are lower and do not exceed 260ºC, another good option is RTD sensors with nickel wires. They are cheaper and offer good features.
However, both nickel and platinum are delicate materials. To prevent them from being easily damaged, they are usually protected with an outer casing made of more resistant materials. For example, some of which are used are stainless steel, resistant aluminum alloys or ceramics.
Important question: Is it possible to increase the length of RTDs? This is sometimes possible and sometimes impossible. They use connecting conductors for resistance temperature detectors. If you need a long wire, check the resistance of every 1 meter of wire to avoid errors.

This effect is usually approximated to a first or second order system to facilitate calculations. RTD sensors are usually associated with Wheatstone Bridge-type electrical assemblies, which respond to the variation of electrical resistance due to the effect of temperature to originate an analog signal of 4-20 mA, which is the one used in the corresponding control system. as a measurement signal. One type of RTD is the Pt100 or Pt1000. These sensors owe their name to the fact that they are made of platinum (Pt) and have a resistance of 100 ohms or 1000 ohms respectively at 0ºC. They are very linear devices over a wide temperature range. Platinum has the particularity of having an extremely linear resistance-temperature relationship, which is why it is the most widely used material and these thermometers are generally called IPRT (Industrial Platinum Resistance Thermometer) or RTD (Resistance Temperature Detector). Platinum has the advantages of:
