Why are thermistors preferred as temperature sensors in many applications?

• A. They are more accurate than RTDs
• B. They are less expensive
• C. They can measure a wider range of temperatures
• D. They are easier to calibrate

Answer: (B)

Thermistors are often preferred as temperature sensors in various applications primarily due to their cost-effectiveness. They are generally less expensive than other temperature sensing options, such as resistance temperature detectors (RTDs). This affordability makes thermistors an attractive choice for both manufacturers and consumers, especially in mass-produced equipment where budget constraints play a significant role. While thermistors can offer advantages in specific performance metrics, such as sensitivity and precision within a limited temperature range, their lower cost is a significant factor in their widespread use. This aspect allows for their implementation in a range of commercial and domestic equipment without significantly inflating production costs. Although thermistors have specific limitations in terms of temperature range and calibration complexity compared to other types of sensors like RTDs, their affordability and adequate performance for many applications justify their popularity.
