RTDs are typically connected with other fixed resistors

Choose the right answer to the question; RTDs are typically connected with other fixed resistors from the following options and a detailed explanation.

  1. in a pi configuration
  2. in a bridge configuration
  3. and variable resistors
  4. and capacitors in a filter-type circuit

Answer - B. in a bridge configuration


The detailed solution to the question, RTDs, is typically connected with other fixed resistors provided here. 

A Resistance Temperature Detector sometimes referred to as a Resistance Thermometer or RTD, is an electronic device that measures the resistance of an electrical wire to determine the temperature. The term "temperature sensor" refers to this wire. An RTD is the best option if we want to monitor temperature accurately because it has good linear properties over a large temperature range.

Metals like copper, nickel, and platinum are frequently employed in RTD devices. Concerning temperature changes, these three metals exhibit various resistance fluctuations. Resistance-temperature characteristics are what those are.

A Wheatstone bridge-shaped temperature transmitter is typically employed to detect the RTD's slight resistance fluctuations. Three well-known and extremely accurate resistors are used in the circuit to compare the RTD value.
