Magnetic platinum thermistorIt is a high-precision and high stability temperature measurement component widely used for temperature control and measurement in various industrial production processes. However, due to the wide variety of platinum thermistors on the market, there are many factors to consider when selecting. Therefore, the following will provide you with a detailed guide for selecting thermistors.

　　

Firstly, we need to understand the basic characteristics of platinum thermistors. Platinum thermistors are mainly composed of magnetic materials and platinum wires, and their working principle is based on the characteristic of the magnetization strength of magnetic materials changing with temperature. When the temperature rises, the magnetization of the magnetic material decreases, resulting in a change in resistance value. By measuring this change in resistance value, the temperature change can be obtained.

　　

When choosing a magnetic platinum thermistor, we need to consider the following factors:

　　

1. Measurement range: Different platinum thermistors have different measurement ranges, and we need to choose the appropriate measurement range based on actual measurement needs. If the measurement range is too large or too small, it may affect the accuracy of the measurement.

　　

2. Accuracy: The accuracy of platinum thermistors refers to the deviation between their measurement results and actual values. Generally speaking, the higher the accuracy, the higher the price. Therefore, we need to choose products with high accuracy as much as possible while meeting the measurement requirements.

　　

3. Stability: The stability of platinum resistance refers to the degree of change in its measurement results over a period of time. The better the stability, the stronger the anti-interference ability of the product, making it more suitable for use in complex environments.

　　

4. Durability: The durability of platinum thermistors refers to their ability to maintain good performance over a long period of use. Generally speaking, the better the durability, the longer the service life of the product.

　　

When choosing a magnetic platinum thermistor, we also need to pay attention to the following points:

　　

1. Choose the appropriate installation method: Platinum thermistors have two installation methods: plug-in and surface mount. We need to choose the appropriate installation method based on the actual installation environment and requirements.

　　

2. Pay attention to the protection level of the product: If there is high humidity, dust, etc. in the working environment, we need to choose products with higher protection levels.

　　

3. Choose a supplier with good after-sales service: Good after-sales service can provide us with timely assistance and support in case of product problems.
