Dial gauges are used to measure machined parts with high accuracy, using plunger, lever, or vernier inputs. They come in analog or digital formats and can measure in small increments up to 500 thousand inches. Plunger gauges are held in place while the workpiece is rotated, while vernier gauges use the movement of the jaws. […]
An optical comparator magnifies and projects an image of an object onto a screen for comparison and measurement. It was developed in the 1920s and is used in production to ensure compliance with standards. The latest advances include video measurement systems that allow ultra-accurate measurements. An optical comparator is a device that magnifies and projects […]
A comparator circuit monitors electrical currents and performs a specific function based on readings from two or more sensors. It is commonly found in timer thermostats and can automate machinery without human intervention. The circuit is limited to the number of inputs implemented and requires a circuit diagram to show the path leading to each […]
A comparator circuit monitors electrical currents and performs a specific function based on readings from two or more sensors. It can be found in devices such as timer thermostats and is preprogrammed to react differently to changing values. Multiple circuits can be wired together for complex equations. A comparator circuit is a programmable device that […]
A digital comparator compares two binary signals using logic gates to determine their equivalence or if one is greater than the other. It is used in CPUs and can handle multiple bits simultaneously. It can also be used in devices that contrast visual images, convert analog signals, or act as a monitor in an industrial […]
