Low Drift Thermistors and Thermistor Assemblies
When using a thermistor as the temperature sensor, it becomes the most important component for the temperature regulating system. To achieve high system performance, the 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 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 thermistors are of this type. When choosing the 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 (+/-0.25C@25C), compact size (bare version down to 0.8mm diameter), and are coated with glass material on all the bare thermistors and the 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 thermistors and thermistor assemblies, let us know. We try our best to help.

The ATH10KR8 is a high precision, low drift, high stability, and extremely compact glass encapsulated thermistor. Comparing with conventional epoxy encapsulated thermistors, the ATH10KR8 features much lower short and long term drifts and wider operating temperature range, especially on the high end: up to 250C. The ultra compact size makies it the best choice for precise, prompt, and specific point temperature sensing applications, such as sensing the laser diodes temperatures, etc. We offer 3 forms of finish: thermistor with bare lead, thermistor with non-sealed tubed leads, and thermistor with sealed tubed leads. The bare lead thermistor can be used for sensing air temperature, the non-sealed tubed lead thermistor can be used for sensing solid material temperature, and the sealed tubed lead thermistor can be used for sensing liquid temperature. The accuracy of ATH10KR8 is 1%.

ATH10K0.6%R8 has higher accuracy of 0.6%, with higher prices.

The ATSC230K-100 thermistor assembly is housed by a stainless steel housing with a stainless flange. The thermistor inside has glass encapsulation to ensure long time operation, wide temperature range, and no parameter drift of either short time or long term. The flange can be used for mounting the thermistor assembly onto a chassis. Both the cap and the flange are made of stainless steel, making them long time lasting even under harsh environment, such as acid, moisture, etc. The output terminals use a pair of heavy duty PVC insulated wires of 26 AWG. The ends are terminated by a standard 2 pin plug, which can be customized for other types of connectors according to customers need. The length of the wires can also be specified.
