Which of the following devices is used to measure relatively high temperatures, such as encountered in furnaces?

Which of the following devices is used to measure relatively high temperatures, such as encountered in furnaces? Correct Answer Pyrometer

The correct answer is Pyrometer.

Key Points

  • Pyrometer 
    • The device for measuring relatively high temperatures, such as are encountered in furnaces. Hence, Option 2 is correct.
    • Most pyrometers work by measuring radiation from the body whose temperature is to be measured.
    • Radiation devices have the advantage of not having to touch the material being measured.
    • Radiation Pyrometers are used to measure the temperature of red hot metals up to 3000°C.
    • It is also known as an Infrared thermometer or Radiation thermometer or non-contact thermometer used to detect the temperature of an object’s surface temperature, which depends on the radiation (infrared or visible) emitted from the object.
    • It acts as a photodetector because of the property of absorbing energy and measuring EM wave intensity at any wavelength.
    • These are used to measure high-temperature furnaces.
    • These devices can measure the temperature very accurately, precisely, pure visually, and quickly.
    • Pyrometers are available in different spectral ranges ( since metals – short wave ranges and non-metals-long wave ranges).

​Additional Information

An ammeter

 
  • It is a measuring instrument used to measure the current in a circuit. Electric currents are measured in Amperes, hence the name.
  • The ammeter is usually connected in series with the circuit in which the current is to be measured.

Barometer
  • It is used to measure local atmospheric pressure.
  • Fluid pressures can be measured regarding an arbitrary datum.
  • The common datum is
    • Absolute zero pressure
    • Local atmospheric pressure
Fluxmeter
  • The search coil magnetometer or induction magnetometer, based on an inductive sensor, is a magnetometer that measures the varying magnetic flux.
  • An inductive sensor connected to a conditioning electronic circuit constitutes a search coil magnetometer.

Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. What inference can be drawn from the above?
The question given below consists of a statement, followed by three arguments numbered I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments and which is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: India’s telecom watchdog has suggested regulation of all entities dealing with consumer data—devices such as iPhones, operating systems such as Android, browsers like Google’s Chrome and apps such as Facebook, Paytm, Uber or Zomato— by bringing them under licence conditions that apply to telecom service providers until a general data protection law is put in place by the government. Which of the following argument weakens the above statement in the best possible manner? Arguments: I. The Telecom Regulatory Authority of India (Trai) said the framework for protection of personal information is ‘not sufficient’ and that the issue of data ownership, privacy, and security is complex and multi-dimensional. It suggested expanding the ambit of licence conditions governing telcos to all entities handling customer information and empowerment of customers to keep their data secure. II. The telecom watchdog further said that individual users owned their data, or personal information, and entities such as devices were ‘mere custodians’ and do not have primary rights over that information. III. Telcos and internet service providers (ISPs) though welcomed recommendations that sought to bring app makers under the same regulations. However, content providers have been opposed to being brought under more regulation.
