Calibration is the comparison and adjustment of a reading from an instrument in correlation with the reading of a higher accuracy piece of equipment. The overall goal of this process is to minimize measurement uncertainty and ensure the accuracy of an instrument.
There are three main types of temperature sensors, and each one has its own strengths and weaknesses. Today we’ll be discussing the advantages/disadvantages of each RTD temperature sensors, thermistors, and thermocouples. Continue reading “How to Choose a Proper Temperature Sensor”
In the past few years, oil production in the United States has skyrocketed. In fact, the U.S. is out-producing many OPEC countries and is currently on track to become one of the largest oil-producing countries in the world, alongside Russia and Saudi Arabia. The top oil producing region in the U.S. is known as the Permian Basin, which includes parts of Texas and New Mexico. Other major oil-producing states include Colorado, Oklahoma, North Dakota, Alaska, and California. Continue reading “Hydraulic Fracturing for Oil Extraction”
Dwyer Instruments, Inc. offers a wide variety of temperature sensors that use RTDs as the sensing element.
RTDs are based on the principal that the electrical resistance of the wire is a function of the temperature, with the resistance increasing as temperature increases. The resistance varies nearly linearly with temperature per the Callendar Van-Dusen equation. The wire used in RTDs as the sensing element is usually constructed of platinum, copper, or nickel. Platinum is the best material for this element, as it has the widest useful temperature range of these materials. It also has a very repeatable and linear temperature to resistance correlation.
