Over the years, temperature measuring devices have gone through various upgrades. It is now at a point where they can provide minute details and readings within a few minutes. These tools are widely popular in industries where the precision of temperature measurement is essential.
Scientists have spent a lot of resources, time, and effort to put the science of temperature measurement in such equipment, thus satisfying the requirements of this industrial niche.
The Equipment
Let’s take an in-depth look into the technology involved in monitoring and measuring the temperature with this super-sensitive device.
- Resistance Temperature Detectors (RTD)
Also known as resistance thermometers or resistive thermal devices, these are the most accurate temperature measuring devices you will ever come across. They are available in different styles but their working principle regarding temperature measurement remains the same. The RTDs contain metal, such as platinum, nickel, or copper to measure the fluctuations in temperature. These devices convey the rise and fall of temperature through a monitoring source like a PC or other device. They are capable of measuring extreme industrial temperatures that can go way beyond 1,000 degrees Fahrenheit.
- Smart Sensors
Sensors usually record any change in temperature or movement of electrical signals and they send relevant data to the monitor assigned to them. But smart sensors go one step further. They not only record normal temperatures but also transmit information to its temperature indicator faster than ordinary sensors. Moreover, these sensors are more accurate than others. Their advanced processing capabilities ensure that they don’t provide any inaccurate information.
- Thermocouple
Thermocouples are not just easy to use; they are also inexpensive. And, they are the most durable type of sensors suitable for sensitive temperature measurement. They can capture even the minute temperature differences, thus making them the appropriate sensors to measure a wide range of temperatures. These sensors are very useful when you need to take temperature measurements quickly.
- Thermistor
It can record temperature within a limited range accurately. A thermistor consists of silicon, polymer, and ceramic. Although a thermistor is inexpensive, it’s not as durable as some of the other sensors like a thermocouple.
The Industries
Many industries depend on the sensitive temperature measuring devices. Here are some of those industries below:
- The steel industry – You will find steel industries using thermocouples widely at various stages of production.
- Power plants – Power plants usually use RTDs to check the temperatures of their fuel and coolant. Additionally, these also use RTDs to monitor the temperature of nuclear power plant reactors.
- Microprocessor Manufacturers – They use programmable RTDs, specially calibrated to record the air temperature in very sensitive environments.
- Aerospace – NASA and the military use multiple temperature measurement devices. Their records provide crucial information regarding jet and rocket engines.
- HVAC – Cooling, heating, and ventilation systems need accurate temperate readings and so, they use thermistors to monitor the temperature fluctuations in the HVAC industry.
- The food industry and the medical field also require consistent temperature monitoring.
The technology in the temperature measurement industry improves every year. These upgrades meet the demands of the ever-changing needs of customers. Monitoring temperature accurately and within a small range are two crucial factors that are essential for these devices.
