2- How to Choose Correct Thermistors
Choosing Correct Thermistors Thermistors are temperature-sensing tools that are sintered semiconductors. The device shows small changes in temperature based on large changes in resistance. Thermistors are made from a mixture of different metals and metal oxides. After the materials are mixed, the thermistor is formed to its required shape. Shaped can be customized and coating can be added to make form bead-style thermistors. There are two types of coating that are possible for thermistors, and this includes epoxy and glass. A glass coating is for high temperature applications. The normal range of temperature is -58 through 572 degrees Fahrenheit. Epoxy coating are the counter-point of glass, so it works best with low temperature. Despite the difference between coatings, they are used to mechanically protect the thermistor and wire connections. The coating also protects against corrosion and humidity. Base resistance is important for a thermistor's performance. The
