What Do You Need to Know Before Looking for RTD Temperature Sensors?
Do you know that temperature is the most frequently recorded and substantial measurement? Understanding the temperature is important for the proper working of everything from an automobile engine to the human body and all that comes in between.
Temperature is measured with accurate temperature sensors. Various temperature sensors, such as thermocouples, RTDs, and Thermistor sensors, are employed for measuring temperature.
In this post, we will talk specifically about the RTD temperature sensors, one of the most prominent temperature sensors among different industries.
Understanding RTD Temperature Sensors
RTD is the short form of Resistance Temperature Detector. It is a kind of temperature sensor that works on the assumption that the electrical resistance of a material varies as its temperature varies.
The basic idea behind RTD temperature sensors is that definite materials show some modifications in their electrical resistance when there are variations in temperature. This variation in resistance can then be employed as an intermediary to check the exact temperature of the material and, by expansion, the surroundings.
Important Things to Know Before Buying RTD Temperature Sensors
Here are some significant points about RTD temperature sensors:
1. Structure and Construction
This sensor normally consists of a fine platinum wire covered all over a ceramic or glass core. The wire’s resistance alters with temperature.
2. Temperature Variations
RTD temperature sensors can be employed over an extensive temperature range, generally from -200°C to 850°C. Even though the accurate range can differ on the basis of the particular construction and design.
3. Precision
These sensors are recognised for their correct temperature measurements, specifically over constricted temperature ranges. The resistance difference in response to temperature in a Resistance Temperature Detector is usually sensitive. This sensitivity makes them helpful for uses where accuracy is needed.
4. Linearity or Dimension
The resistance modification in the sensor is quite linear with temperature variation, specifically compared to different temperature sensors such as thermocouples. This signifies that for each degree change in temperature, the resistance varies by an identifiable and constant amount over a factual range.
5. Constancy
Unlike other sensors that may clump or diminish over time, Resistance Temperature Detectors, particularly those constructed of platinum, manage their features over extended periods. This long-term constancy is precious in uses where recalibration may be difficult or expensive.
6. Configuration
Resistance Temperature Detectors can be configured in setups of 2, 3, or 4-wire. The 3 and 4-wire structures reduce the impact of lead wire resistance on the temperature evaluation, which makes them more precise.
7. Types
The most general type is the Pt100, which has 100 ohms resistance at 0°C. Other types, such as Pt500 and Pt1000, have resistances of 500 and 1000 ohms at 0°C, consequently.
Different Applications of RTD Temperature Sensors
There are various industry applications of RTD sensors. These sensors are utilised in a wide variety of applications because of their accuracy, constancy, and dependability. Many times, they are used in industrial surroundings where a higher standard needs to be maintained. You will see this equipment on factory floors, refrigeration units, labs, manufacturing plants, oil rights, and more.
1. Pharmaceuticals Industry
In pharma manufacturing and storage, keeping precise temperatures can be essential. These temperature sensors assist in ensuring that products are manufactured and stored under proper conditions, following the strict rules that pharma companies must conform to.
2. HVAC Systems
HVAC or Heating, Ventilation, and Air Conditioning systems use Resistance Temperature Detectors to make sure surroundings are kept at the required temperatures. For example, they are ideal for cooling towers because their precision and stability change into lasting stability for the system.
3. Labs
In science and research labs, Resistance Temperature Detectors help maintain and monitor the temperatures of critically stored materials. Thus ensuring precision and trustworthiness in results. Their increased accuracy and linearity ensure that experiments do not generate defective data.
4. Semiconductor Production
The semiconductor manufacturing needs accurate temperature control, and RTDs play an important role in making sure that these temperatures are managed properly.
5. Refrigeration industry
Resistance Temperature Detectors help track and control the temperatures in refrigeration units, assuring the most favourable conditions for the stored goods. They are specifically precious for conditions where very increased accuracy is needed in the case of medical laboratories.
6. Renewable Energy
In solar thermal power, RTDs can check the temperature of the heat transfer liquid, making sure that the system is working effectively. They are also used in automatic solar systems where the panels move on the basis of optimising the solar emission intake in association with the operating temperature.
7. Oil and Gas
In the oil and gas industry, RTDs can be employed downhole to assess temperature in wells or to check the temperature of devices and procedures at refineries. They are the preferred option, as a minute of variation in the temperature can lead to severe incidents. Therefore, a highly sensitive sensor is needed.
