NTC Thermistors and Thermistor Assemblies

Advantages of Thermistor vs. All Other Temperature Sensors
Temperature snesors are widely used in industry and consumer products. Among them, thermistors are the most commonly used type. It has the highest sensibility, low noise, is simple to use and of low cost. Its main shortcoming is low accuracy. In otherwise, interfacing with a same circuit, using different thermistors of the same value can result in different temperature readings. Therefore, for high accuracy applications, thermistor temperature sensors are not interchangeable. RTDs, on the other hand, has high interchangeability, linear characteristics, wide temperature range, but low sensibility and higher cost. Temperature ICs has good linearity and sensibility, but limited temperature and high cost. Thermal couple has the widest temperature, good linearity, but low sensibility and requires high cost temperature compensation circuit on connectors.

When using a ntc thermistor as the temperature sensor, it becomes the most important component for the temperature regulating system. To achieve high system performance, ntc thermistors should have low short term and long term drifts in the R-T relationship, the resistance vs. the temperature, compact size, and reliable. Some low cost ntc thermistors are coated with epoxy materials and have large short and long term resistance drift, i.e., when sensing the same temperature, the resistance changes with time, causing the system with a wrong sensed temperature, thus, the target object temperature is drifted. Glass coated thermistors, on the other hand, have almost zero short and long term drift, all our ntc thermistors are of this type. When choosing ntc thermistor for a temperature control system, these are the main specifications to consider: operating temperature range, sensitivity, drift, size, mounting approach, etc. Our thermistors and thermistor assemblies are mainly ntc thermistors, and can be used with our TEC controllers and TEC modules for building high stability low drift temperature control systems. These ntc thermistors and thermistor assemblies have high precision (+/-0.25°C@25°C), compact size (bare version down to 0.8mm diameter), and are coated with glass material on all the bare thermistors and ntc thermistor of which the thermistor assemblies are made, resulting in low both short and long term drift. The ntc thermistors come in bare and lugged forms, the former is for point sensing to achieve high accuracy for specific points, such as laser diode die, etc.; the latter is for bulk temperature sensing, such as optical components, etc. If you have any questions about choosing and using ntc thermistors and thermistor assemblies, let us know. We try our best to help.
