There are different types of sensors ranging from brands and materials used. With the increasing sensors in the market, the custom resistance temperature detectors are the best at detecting changes in electrical temperatures. Most of these detectors are made up of a coiled wire that is wrapped around a glass or ceramic core. Choosing the sensor with the most durable material is the best bet towards having a long lasting sensor.
The most common materials used to make these sensors are copper, nickel and platinum. The material that has proven to be the best is platinum. This is because it is one of the metals that have the most resistance even in the largest temp ranges. This is because it is one of the most stable elements since it can withstand extremely high temperatures unlike other elements. Platinum is also chosen as the best due to its chemical inertness a characteristic that makes it the best.
Also, the platinum which is the best material to use for the temperature sensors has a wide range of pros. For instance, it is very stable, highly accurate and is very suitable for applications that require high precision. Platinum detectors are a double edged sword of some sort. This is because; with the many pros so are the cons depending of the set function. With increased temperatures above a certain point, it becomes extremely easy for the detector to be contaminated by impurities. Ones contaminated, the effectiveness of the detector suddenly decreases drastically.
On the other hand, copper is also a very good material for sensors. It has a very stable resistance. The only shortcoming is that it easily gets oxidized and can thus not be used beyond a certain temperature. This makes it less favorable since constant replacements will be required unlike the platinum sensors.
With the many brands in the market, it is important to avoid being scammed. This can only be done if the buyer does a thorough research on the different manufactures. This is done by going through the different customer reviews to rule out all doubt on the detectors. This also helps in knowing any defects and problems to expect if they choose the given brand.
Also, the sensors are very easy to calibrate and give the anticipated readings over very narrow temperature periods. This is as a result of the enhanced features that have been added to each of them. This has not only improved performance but also contributed towards creation of great inventions.
The wire wound sensors work by providing an interaction between the mechanical stability and allowing expansion of the wire to minimize strain and any changes that may take place as a result. The winding core is always an electrical insulator. It is far much more accurate than the thin filmed as is mostly recommended over the thin filmed.
The thin filmed detectors work by depositing a thin film of the resistant material which could be platinum nickel or copper around the ceramic material. The film is then covered with a glass or ceramic that helps protect the deposited film and also acts as protection for the external lead-wires.
