A digital external micrometer, also known as an outside micrometer, is a handheld measuring tool used to measure the external dimensions of an object with high accuracy. It is commonly used in manufacturing, machining, and engineering applications where precise measurements are required.
Unlike traditional micrometers, which use a vernier scale or dial gauge to read measurements, digital micrometers use an electronic digital display to provide accurate readings. The measurement range of a digital external micrometer typically ranges from 0-25mm or 0-1 inch, but can vary depending on the model.
Digital External Micrometer
The micrometer consists of a calibrated screw and a measuring spindle that moves along the screw to provide precise measurements. The spindle is brought into contact with the object being measured, and the screw is turned until the two surfaces are in light contact. The reading is then taken from the digital display, which can be accurate to within a few thousandths of an inch or hundredths of a millimeter.
Digital external micrometers are known for their ease of use, accuracy, and speed, making them an essential tool for professionals in various fields. They are commonly used to measure the diameter of shafts, bolts, and screws, as well as thickness and width of various materials.
In addition to their accuracy and ease of use, digital external micrometers offer a range of other benefits. For example, they typically have a zero-setting button that allows the user to reset the measurement to zero at any point during the measurement process. This helps to eliminate errors caused by misalignment or accidental movement of the micrometer.
Another advantage of digital micrometers is that they often have a data output feature that allows the user to transfer measurement data to a computer or other device. This can save time and reduce the risk of errors associated with manual data entry.
Digital external micrometers are available in a range of sizes and styles to suit different applications. Some models have additional features such as a carbide-tipped measuring face for increased durability or a depth gauge attachment for measuring the depth of holes or recesses.
Overall, a digital external micrometer is a valuable tool for anyone who needs to take precise measurements of external dimensions. With their accuracy, ease of use, and range of features, they are an essential tool for professionals in many industries.
How to choose a outside micrometer?
When choosing a digital external micrometer, there are several factors to consider to ensure that you select the right tool for your specific needs. Here are some key considerations:
- Measurement range: Consider the range of measurements that you need to take. Choose a micrometer with a measurement range that is suitable for your application.
- Accuracy: Most digital micrometers have an accuracy of around 0.001 inches or 0.01 millimeters, but some models may offer higher or lower accuracy.
- Display: Digital micrometers typically have an LCD display, but some models may have additional features such as a backlight or larger display.
- Resolution: This is the smallest unit of measurement that the micrometer can display. A higher resolution means that the micrometer can provide more precise measurements.
- Material and durability: Look for a micrometer that is made from high-quality materials and is built to withstand repeated use.
- Additional features: that you may need, such as a zero-setting button, data output, or depth gauge attachment.
- Brand and price: Look for a reputable brand that offers a good warranty and customer support. Prices can vary widely depending on the features and quality of the micrometer.
By considering these factors, you can choose a digital external micrometer that meets your specific needs and provides accurate and reliable measurements for your applications.
How many type of outside micrometer?
There are several types of outside micrometers available, each with their own unique features and applications. Here are some of the most common types:
- Mechanical Outside Micrometer: This is the traditional type of micrometer that has been used for many years. It uses a vernier scale or dial gauge to provide measurements and is typically accurate to within 0.001 inches or 0.02 millimeters.
- Digital Outside Micrometer: uses an electronic digital display to provide measurements. It is typically more accurate than a mechanical micrometer and can provide readings to within 0.0001 inches or 0.001 millimeters.
- Vernier Outside Micrometer: This type of micrometer uses a vernier scale to provide precise measurements. It is typically more accurate than a mechanical micrometer and can provide measurements to within 0.0001 inches or 0.001 millimeters.
- Depth Outside Micrometer: used to measure the depth of holes or recesses. It has a longer measuring spindle than a traditional micrometer and can provide measurements up to several inches deep.
- Tube Outside Micrometer: This type of micrometer is used to measure the diameter of tubes or pipes. It has a cylindrical measuring face that can fit around the outside of the tube to provide accurate measurements.
- Blade Outside Micrometer: This type of micrometer is used to measure the thickness of blades or other thin objects. It has a narrow measuring face that can fit between the two surfaces to be measured.
The specific type of outside micrometer that you choose will depend on your specific application and the level of accuracy that you require.
