The purpose of calibrating services is to take a measurement of the precise output of a device, usually in terms of its power. This reading can then be compared with the manufacturer’s standards to find out if the device is running both safely and efficiently. A calibration device uses electrical signals as a means of calibrating instruments or other devices. After the exact margin of error has been discovered, the calibrator can adjust the instrument to the manufacturer’s specifications for improved output.
Usually an instrument that needs calibration must be taken to an expert, or a field technician should be called to visit. In industrial settings, any device that depends on pressure, temperature, or speed should be calibrated to ensure efficiency. This could create a significant cost-savings and maintain the safety of the equipment.
In medical and lab settings, pipette calibration is used, while in more basic applications torque wrench calibration is common on nuts and bolts. For scales, load cell calibration helps to yield accurate weight measurements. A hardness test measures the hardness of a given material, providing valuable information like the level of resistance to deformation. To maintain accuracy, regular calibration is the best solution. In many industries, regular calibration is not only recommended but required to meet safety and efficiency standards. Read More…
Not all calibration is done on a work site. Smaller devices and instruments are often sent to calibration laboratories for further testing by professionals. In these labs, pipettes are a common tool. A pipette dispenses measured quantities of liquid for lab or medical use. Accuracy is critical in these environments, so the pipette must be calibrated correctly. For instruments that measure or control pressure, pressure calibration is performed. Temperature calibration is specifically for devices that measure or control temperatures, like detectors or thermostats.
To accurately measure speed in a vehicle or some other piece of machinery, speedometer calibration is used to keep the reading precise and account properly for distance. In automotive applications, this precision keeps drivers safe by giving them the information that they need to drive within the speed limit. Torque, the product of force and distance, can be calibrated on a torque wrench for improved accuracy. This is important for the threading of nuts and bolts so that over or under-tightening does not occur.
The many different types of calibration make it necessary for a variety of calibration methods and tools to be used. A load cell converts a force into an electrical signal that can be measured to help show accurate weight measurements. Machines wear down over time, causing a decline in performance and efficiency. This is why machine calibration is important, particularly in industrial settings.
Calibration tools vary greatly. Some are handheld, some are fixed, and some are even portable. A handheld calibration device is usually small and manually operated. Portable devices may be large and mounted on wheels so that they can be moved around a facility as needed. In factories or other workplaces, fixed calibration instruments remain stationary and are used during production as needed.
Electronic technology has served to dramatically improve the ability of calibration services. Most sensors and transducers can now provide more accurate measurements than ever before. These tools are also more versatile than they were in the past, and some are even capable of measuring different types of instruments in multiple locations for comparison. This high degree of precision was never possible when manual calibration methods were used. Advanced in electronic technology have made it possible to gauge exact numbers on high tech equipment to maintain high performance.
National regulations for performance and calibration are enforced by agencies like the National Institute of Standards and Technology. This helps to create standards that are applicable for safety and efficiency across the country. It should be noted that although calibration devices are powerful, they are not perfect. To be truly accurate, every factor that affects the calibration of an instrument must be known. The possibility of error is always present, but electronic calibration methods have greatly reduced the margin of error.
