Thermistors for Temperature Measurement, Compensation, and Control

Negative Temperature Coefficient NTC Thermistors are semi-conductor non-linear resistors, which alter their resistance characteristics with temperature and the resistance of the NTC thermistor will decrease as the temperature increases.

Ametherm’s NTC thermistors are manufactured from a specially-formulated high quality metal oxide ceramic material which is extremely accurate in sensing temperature used in Temperature Measurement, Compensation, and Control applications.

Designing a Furnace Fan and Limit Controller Using an NTC Thermistor and an Arduino Microcontroller

Written By Joe Conti NTC thermistors are a great way to control the power functions of a residential furnace system. These thermistors can sense the air temperature in the furnace heating chamber and turn the power on and off. Replacing the power control of the furnace with a temperature sensor is easy to do. This article will walk you through how to do this starting with an Arduino microcontroller and … Continue Reading

Using Epoxy to Protect NTC Thermistors

One common way to protect NTC thermistors from damage that might impair performance is to encase them or house them in epoxy. The chemical characteristics used to protect NTC thermistors are found in industrial grade epoxy with a high dielectric strength and thermal conductivity. An epoxy coated NTC thermistor temperature sensor appears as a tear-drop-shaped bead with two radial wire leads. Very often these types of NTC thermistor temperature sensors … Continue Reading

When to Use NTC Thermistor Probes and Why It’s Necessary

NTC thermistor probes have long been employed to measure liquid levels and temperature in industries that extend from automotive electronics to medical technology to green energy. Their applications are endless, and their purpose is significant. A thermistor probe is otherwise identified as a bead thermistor manufactured as a bare bead encapsulated with epoxy or glass that is usually potted in a metal or plastic housing with two high temperature insulated … Continue Reading
