Selecting Thermistors and Temperature Sensors

NTC thermistors have many typical applications. They are used in automotive applications for transmission oil temperature control, electronic airbag systems, and frost sensors. Thermistors are necessary for many domestic appliances like air conditioners, central heating systems, and refrigerators. ThermistorsThese devices can also be found in industrial, consumer, and telecommunication devices and systems. Because NTC thermistors operate in many different applications, there is a wide range of options available to consumers. There are five steps everyone should take before making a purchase. These steps include:

Step 1­­- Choose a sensor series you need. Choices are dependent upon more than just the operating temperature range. You must also factor in product size, accuracy, lead diameter and length, and needed mechanical execution.

Step 2- You must take the time to decide on R25 value. You can refer to the R/T characteristics of sensor series that are chosen in step 1. Making this determination gives users the best fit for electronic measuring of the current range and circuit voltage.

Step 3- After getting the value of R25, you now must determine the tolerance.

Step 4- Use R/T tables on specific datasheets to select a sensor from the series that meets your requirement (calculated in step 3).

Step 5- Selection charts allow you to make a smart decision about the length of part and response times. Standard ranges create narrow tolerance at 25 °C. Our custom thermistors can maintain the tightest tolerance at whatever tolerance needed. Make sure you give us your request for a custom thermistor.
