Digital Calipers.

What are Digital Calipers?

A digital caliper is a precision measuring tool used to determine the dimensions of an object with incredibly high accuracy. Unlike traditional calipers, a digital caliper features an electronic display that shows measurements instantly, eliminating the need to interpret scales manually.

These electronic calipers come equipped with the same precision internal, external and depth-measuring jaws, providing versatility for a wide range of applications. The digital vernier caliper combines the classic vernier scale with modern electronic technology, enhancing precision and user experience.

How Digital Calipers Work

Digital calipers operate using a linear encoder system that translates the physical movement of the jaws into electronic signals. When you slide the jaws of an electronic digital caliper, the encoder detects the position and displays the measurement on a digital screen. This technology allows for quick switching between metric and imperial units, catering to diverse measurement requirements.

Industries like aerospace, automotive and manufacturing rely on electronic vernier calipers to measure components with stringent tolerances. For instance, a digital caliper can accurately measure the diameter of engine pistons or the thickness of brake discs, ensuring they meet exact specifications. There's even the option to send a digital readout of the measurement into software to accurately log the data should it need to be referred back to.

Materials Digital Calipers Are Made From

Accu's selection of digital calipers is made from hardened plastic or stainless steel. Hardened plastic electronic calipers are lightweight and resistant to conduction, making them suitable for environments where metal tools might interfere with sensitive electronic components.

Stainless steel digital calipers on the other hand offer superior durability and are ideal for heavy-duty applications where a quick readout is paramount. The robust construction of a stainless steel electronic digital caliper ensures longevity and consistent accuracy, even in demanding industrial settings. The choice of material impacts the tool's resilience and suitability for specific working conditions.

Size and Types of Digital Calipers Available

At Accu, we offer a comprehensive range of digital calipers to suit various measurement needs. Our digital calipers range from the smallest size of 100mm (4 inches) to the largest size of 300mm (12 inches), accommodating both small and large-scale projects.

Some models come with advanced features such as Bluetooth connectivity for seamless data transfer, external readouts for enhanced visibility, and IP67 or IP54 ratings for dust and water resistance.

The jaws of our digital vernier calipers are designed for internal, external and depth measurements, providing versatility in one tool. We stock leading brands like Fowler and Insize, known for their quality and reliability.

For specialised applications, you might also consider our range of dial calipers or vernier calipers, which offer alternative methods of precise measurement without the need for a power source.

FAQs

Q: Is a digital caliper accurate?

A: Yes, digital calipers are highly accurate, typically offering precision within 0.02mm or 0.001 inches. The electronic display provides instant, clear measurements, minimising human error. This makes them ideal for precise tasks in machining, engineering and quality control.

Q: Which is better: digital or analog vernier caliper?

A: It depends on your needs. Digital vernier calipers offer easy-to-read displays, quick unit conversions, and reduce reading errors making them convenient for most users. Analog calipers don't require batteries and can be more durable but require skill to read accurately. For convenience and precision, digital calipers are generally the better choice.

Q: What are the disadvantages of a digital caliper?

A: Digital calipers rely on batteries, so you'll need replacements on hand to avoid downtime. Without proper IP ratings like IP54 or IP67, they can be sensitive to dust and moisture. They are also typically more expensive than analog versions due to their electronic components.

Q: Do digital calipers need to be calibrated?

A: Just like any caliper, regular calibration checks to using a gauge block are important to confirm their accuracy. Over time, even high-quality digital calipers can experience slight deviations this can be due to wear or damage. Unfortunately, if this is the case, the best case of action is to order a replacement as re-calibration is often not an option.
