Considering Different Bead Type Thermistors

There are several different types of thermistors on the market today, and each of them offers a unique function. In the following article, we will be going over several different types of bead-type thermistors. These thermistors, although different, provide users with incredible stability and consistency. thermistorsThese thermistors operate with an extremely fast response time, and they can all work under hot temperatures. These items provide users with great functionality, but that comes at a cost for the user. These thermistors are usually more expensive to make than thermistors that have a metalized surface. Different types of bead thermistors are available, and it is important to understand the difference between them before making any purchases.

Glass can be made thin, and when used in thermistors the combination provides a very stable product. Glass seals are some of the best on the market, but there is a big consideration. Considering they are made of glass, they are rather fragile. The glass can crack easily and then the seal is broken. If purchasing and using these devises, you should be extremely careful when handling. 

Bare beads are great and inexpensive, but they only work in certain environments. These thermistors have almost no protection whatsoever against the environment and weather. These devices shouldn't be used unless proper care is taken when setting them up. This means getting the exact mounting and stain relief where needed.

A ruggedized version of beaded type thermistors gives users the ability to continue assembly and handling. It is made of a thick glass, so it gives the same stability as glass-coated beads but also provides more durability. These are more expensive than their thinner counterpart, but they are for a reason.

If you need a thermistor that handles well while being submerged, then you will want to consider a miniature glass probe. It has an elongated body, which makes them handle and function better when under liquids. This is a very stable device.

A glass probe is different than a glass rod. First, a glass probe is something that is sealed inside of the top of a wide solid glass rod. These probes are usually the simplest to use and most durable bead type thermistor. A rod is has the thermistor sealed in the middle of the rod. The other difference is that the rod has axial leads, which make then easier to mount on circuit boards.
