All you need to Know About NTC Thermistors

by Sanjeev Yadav SEO Consultant

The NTC Negative temperature coefficient thermistors are made up of sintered metal oxide. They show a large decrease in resistance in the proportion to the small increases in the temperature. Its resistance is calculated by passing a measured and small direct current through the thermistor and then measuring the produced voltage drop. There are many factors which you will need to know about the bead type NTC thermistors manufacturer.

Here are some of the factors which you must consider while selecting an NTC Thermistor.

Accuracy-

• An NTC thermistor has some of the basic types of sensors which can achieve the highest accuracy which stays within the range of -50°C to 150°C.

• And the thermistor’s which are glass encapsulated range till 250°C and its accuracy fall within 0.05°C to 1.00°C.

Temperature range-

• When you choose a temperature sensor, the very first thing which you should consider is the temperature range of application.

• The NTC thermistors are very well suited for a pretty wide range of different applications in various industries.

• And they perform pretty well in an operating range of -50°C and 250°C.

Stability-

• If you are searching for a long term operation, then it is important that you an application with good stability.

• The temperature sensors can over time, drift themselves depending upon the construction, material and the packaging.

• An NTC thermistor which is epoxy coated changes per year around 0.2°C. Whereas the one which is hermetically sealed only changes by 0.02°C every year.

Noise immunity-

• The NTC Thermistors offer excellent immunity to lead resistance and electrical noise.

Packaging-

• The packaging requirements are assigned by the surroundings the sensor will be used.

• The bead type NTC Thermistors wholesale supplier supplies products that can be potted and customised into different housings depending on the application requirements.
• For further protection, they can be glass encapsulated or epoxy coated.

Bead type NTC thermistors –

• These thermistors are made from alloy, platinum, lead wires all directly sintered into the ceramic body. These usually offer better stability, faster response time and allows operations at a higher temperature than Chip and Disk NTC sensors.

• However, as they are more fragile, it is safe if it is sealed in glass for protecting them from the damage which will happen during the assembly. And also for improving the measurement stability.

What are the different bead type thermistors-

In the market, you will find many types of thermistors and each of them has its unique functions. Here are some of the common bead type thermistors.

• These thermistors are pretty different but they provide amazing consistency and stability. They work with incredible response time, and they also work just fine under hot temperatures.

• The bead type thermistor is slightly more expensive than the other one’s which have a surface of the metal.

• Bare beads are inexpensive and work just fine, but they can only work in a particular environment. These thermistors almost have no protection against the weather and environment.

• When you set them up, you have to take proper care of them or else they can not be used. Which means getting stain relief and exact mounting wherever it’s needed.

• A rugged version of the bead type NTC thermistors supplier in India provides its users with an ability to continue handling. Thick glass is used for making it so that it provides the same amount of stability as the glass-coated beads. But it also provides more durability.

Choose such a bead type NTC thermistors supplier in India who are renowned for their great quality products. Choose such a supplier who delivers the fairest quality of products to its customers.

Before you choose a bead type NTC thermistors manufacturer make sure their products are all made with the supreme quality of raw materials. And are duly tested at each stage of packaging and production.
