Temperature Sensors
Moisture and temperature sensors: process sensors every industry rely on
Industries nowadays cannot put a product for sale into the market or distribute it to wholesalers or other manufacturers if it does not keep up with the strictest and highest industrial quality standards. Industry managers and factory operators are well aware of the fact that their products need to meet certain specific standards so that the final customer is pleased with them and is willing to acquire another one soon.
Industries and factories nowadays, therefore, have to keep a close control of the different steps comprised in their manufacturing process. Sometimes, operators can use their own hands and eyes to make sure that everything is running on smoothly but most of the times they need to rely on external monitoring devices to help them check if there is something that needs to be changed. For instance, they can be using extremely hot materials that cannot be touched to see if they are too hot or not hot enough, or they are drying malt seeds to prepare beer and they drying oven is too hot and they cannot just stick their heads into it to see if the environment is dry enough for the seeds to be used properly in the following steps of the process.
In such occasions, as it has already been said, industries rely on process sensors that enable them to control those aspects of the manufacturing process that they cannot monitor themselves. Process sensors are highly sensitive devices that are used in different industrial procedures to monitor all different kinds of stages and elements. There are different types of process sensors but the two most common ones are temperature and moisture sensors.
Temperature sensors are, of course, thermometers but, unlike the ones you are probably most familiar with and that you use to check if your children have a fever, these can measure extremely high temperatures without putting the factory operators at risk. There are different types of temperature sensors that can tolerate different temperature ranges and that have different levels of accuracy. Most of them are made of specific metals that, when in contact with the surface to be measured, they can automatically tell the operators if the temperatures are right or if they need to be modified. The most sophisticated ones can even measure temperatures without even touching the surface to be measured.
Humidity sensors or hygrometers can help factory operators know if a product being manufactured is dry enough or if the humidity level in the environment is the correctly. Some products are very sensitive to moisture and if the environment is too wet or too dry they can alter severely the final quality of a product.

What type of sensors measure temperature and how does it work?
How do sensors work?
First and most obvious is the mercury or alcohol in glass thermometer.After that are thermocouples ;two different metal wires welded together at their tip(called the 'hot junction) and then joined to two conductor wires to the measuring apparatus.The joint at the conductor wires is the 'cold junction' which is kept a a constant temperature (usually the melting point of ice or some other controlled temperature.The thermocouple hot junction develops a voltage in the millivolt range which is used by potentiometric methods to measure and control temperatures either above or below the cold junction temperature.Some thermocouple devices use non-metallics instead of metals; an example is the graphite /silicon carbide junction.
Other methods include the platinum resistance thermometer and also the bending of a bimetallic strip.In the bimetallic strip two metals with different coefficients of thermal expansion are fixed face to face often the compound strip is wound as a loose spiral.On heating or cooling the strips expand at different rates and the compound bends ,or if a spiral,rotates and this idea is used to measure temperature and with electrical contacts,control it.
Others I forgot I forgot,because I never used them, are the radiation pyrometer (Based on the Stephan -Boltzman Law) one such is the Fery total radiation thermometer ;following would be the disappearing filament pyrometyer and last the old pottery device called a Seger cone,not accurate, it depends(depended?) on the cone in the furnace melting and bending over under gravity-OK for a rough idea in a hot remote cave.Edit.There you go, I forgot the new medic's infrared thermometer and thermal imaging in general.
