Why You Need a Temperature Gauge
A temperature gauge is often used to monitor the temperature of an object or area. A thermometer normally measures the amount of heat that is in an object or area by using a mercury or thermocouple element. The difference in a mercury or thermocouple element and the surrounding atmosphere is what is measured by the thermocouple element. The thermocouple element can also be replaced with a mercury plug if the environment is hot and cold at the same time. If the temperature is higher, the plug will be heated up and thus the temperature that is measured by the thermocouple element is the one that is read.
An example of a thermocouple gauge would be the one you would use to monitor a refrigerator. The mercury element that the thermocouple is fitted to will detect the amount of heat that is in the room. This will allow the person who is reading this to know if the room is overheated or not. The meter that is connected to the temperature gauge can tell you the exact temperature the room has reached. If the person reading the gauge has their hands near the mercury plug when the gauge reads that the room is cool, then they will be reading the temperature of the room to see if it is too warm.
A temperature gauge used for an air conditioner is a bi-metal gauge. These are usually used for the air conditioning systems and are used with the help of two mercury plugs and one thermocouple. The difference in the two elements, depending on the season, can be used by the air conditioner to tell whether the system needs to work harder or if it is working correctly. It is vital that the air conditioner uses the correct gauge for the system in order to get the correct readings. You would need a gauge that is specifically made for the type of air conditioner you have so that the measurements that are being made will be accurate. A good gauge should be able to give you the correct information so that you know what changes need to be made to make your system run more efficiently.
