Environmental factors can make a huge difference in the quality of your facilities. As a result, it can be vital to ensure that the equipment that regulates those factors is fully functional and accurate. At Northeast Metrology Corp., we are fully equipped and ready to to calibrate a wide range of equipment, including Thermocouples (Type K, S, T), Thermometers and Temperature Controllers.
Infrared pyrometers measure the heat radiated from an object, through using electronic signals to sense emitted infrared energy. The the use of energy detectors concentrated though lenses, the pyrometer can read energy as a temperature unit. This is useful in that no direct contact is required with the object, which means it won’t interfere with the formation of the metal. If a sheet of metal receives insufficient heat, the end product is greatly weakened; the same is true if a metal product is overheated and becomes too brittle. The pyrometer allows you to have a sound reading of the temperature all throughout the process, ensure the highest quality result. Additionally, infrared pyrometers can save energy by increasing overall efficiency, eliminating machine downtime, and catching errors.
Thermocouples are devices used to measure temperature, composed of two different metals that produce a low voltage when joined together. A thermocouple then reads the voltage produced. Thermocouples are manufactured from a range of metals and typically register temperatures between 200 and 2,600 degrees Celsius (C). Depending on the types of metals in the thermocouple, the specific temperature range will vary.
For thermocouple calibration, various types of measuring equipment, standards, and procedures must be in place. A control temperature needs to be established that provides a constant temperature; it must be uniform and cover a large enough area that the thermocouple can adequately be inserted into it. Fixed points, sources of controlled temperatures, are composed of a metal sample inside a graphite crucible, with a graphite thermometer submerged in the sample. When this reaches the freezing point, it maintains a very stable temperature, between the solid and liquid phases. A reference temperature must also be established; typically, 0 degrees C is used. A measuring instrument, such as Fluke 702 calibrator, can be used to measure thermocouple output.
It’s important to maintain a constant temperature or adequately control temperature, especially in equipment that requires minimal operator involvement or is exposed to periods of extreme temperatures and frequent thermal cycling. Our Temperature Controller Calibration services will verify the accuracy of the device’s measured output to the expected output as stated by the manufacturer’s specifications or other requirements, ensuring that your equipment is functioning at the ideal level.
