Ametherm is pleased to announce its participation in Sensors Converge, a prominent event for the sensor industry, taking place in Santa Clara from June 20th to June 22nd, 2023. Ametherm will be unveiling its latest advanced thermistors, designed to deliver exceptional performance and reliability in temperature sensing applications. Ametherm’s thermistors provide exceptional accuracy and precision, enabling access to quick and accurate data during the most critical of applications. With their versatility and reliability, these thermistors provide manufacturers with reliable temperature sensing.
Ametherm NTC Thermistors as temperature sensors
NTC, short for Negative Temperature Coefficient, represents a type of thermistor leveraging the resistance properties of ceramic/metal compounds for temperature measurement. Ametherm's comprehensive range of NTC sensors presents numerous benefits in temperature detection, including compact size, enduring stability, and precise accuracy. NTC Thermistors exhibit a resistance alteration of 3 to 5% per degree Celsius, making them widely utilized as temperature sensors in various electronic applications.
Originally uncovered in 1833 by Michael Faraday during his exploration of silver sulfide semiconductors and subsequently brought into commercial use by Samuel Reuben in the 1930s, NTC thermistors feature oxide semiconductor ceramics containing elements like manganese (Mn), nickel (Ni), and cobalt (Co).
Due to their characteristic of decreasing resistance with rising temperature, NTC thermistors find ubiquitous application in everyday life. They serve as key components in thermometers, air conditioners, smartphones, kettles, irons, and even as current regulators in power supply systems. With the ongoing shift towards automotive electrification, there has been a proliferation of NTC thermistor products tailored for automotive usage.
In contrast to conventional metals whose resistance escalates with temperature, NTC thermistors exploit this negative coefficient behavior, wherein increased temperature diminishes the average mobility of free electrons due to heightened lattice vibration within the crystal structure.
Ametherm NTC thermistors are used in a wide variety of applications:
- The medical industry relies on NTC's in various applications including catheters, dialysis equipment, and patient monitoring.
- Appliances from dryers to coffee makers use NTC thermistors to accurately measure temperature.
- HVAC and refrigeration equipment use NTC sensors to measure temperature in building controls and processes, resulting in increased efficiency and control.
- Automotive and aerospace industries use NTC thermistors for test and measurement as well as production applications.
