Temperature changes are often a result of different interactions in the process. Monitoring these temperature changes is critical. If the temperature change becomes too big, equipment or process can be damaged, and dangerous conditions can occur. If the temperature change is too small, the system might not be working properly or has become highly inefficient. Fortunately, such temperature changes are easily monitored with a thermocouple.
It is a portable device that can be used to monitor the temperature changes in various types of equipment. The device is simple to use. Its two probes are attached to two different points. The difference in temperature is converted to electricity, and that electricity is measured by the device. This helps you to determine if what you are measuring is within acceptable parameters or if adjustments need to be made to the equipment.
They are able to do this because their two probes are made up of two different metals. These metals have a known expansion rate when heated. When they expand, they give off a certain amount of energy. Because they expand at different rates, the change in the energy is noted on the meter. These probes have to be composed of different metals in order to create a readable circuit. If they were composed of the same metal, the meter would essentially read zero because there would be no change in voltage to measure.
Some of the metals the probes are composed of include nickel, chrome and iron. The type of metals used for the probes depends on what types of temperatures are being measured. When determining which of them are used, it is important to read temperature ranges because they can vary. Some devices are designed for high levels of temperature changes, such as what you would find in a furnace. Others are designed for more subtle changes, such as what you would find in determining the temperature of a room in a thermostat.
The knowledge of temperature changes is a key part of many industries. Ensuring that they are measured correctly is essential in determining whether a machine is working properly.
