How to select the right thermistor / temperature sensor ?
1. Resistance Value
2. Resistance Temperature Characteristics
3. Resistance Tolerance and Temperature Tolerance
4. Operating Temperature
5. Mounting and Assembly
6. Configuration
7. Cost
8. Special Requirement
Resistance Value
NTC thermistors are typically specified or referenced with a resistance value at 25 °C. However, it is equally important to consider the minimum and maximum resistance values at the extremes of the operating temperature range.
Resistance Temperature Characteristics
Thermistors may be specified with either a temperature tolerance or a resistance tolerance at either a single temperature point or over a temperature range
Configuration
NTC thermistors come in several forms: bare discs, bare chips, glass coated beads, radial leads, thin film, surface mount, etc. The leaded styles are available with different housings, lead lengths, and encapsulation.
Mounting
Depending on application, mounting methods vary from screw mounts, pipe straps, tape or glued in. Please contact our sales representative for more information.
Special Requirement
Should special requirement such as space limitation, harsh environment, response time be considered, please be sure to let our sales representative know.
