Analog waterproof dial gauge – SA021EW

The analog waterproof dial gauge is an instrument designed to detect linear displacement and perform comparative dimensional inspections in all contexts where, in addition to measurement readability, improved protection during use is required. It is a useful solution in workshops, quality control and machine-side inspection when deviations, dimension differences, runout or very small variations must be checked with immediate reading.

The operating principle remains that of a dial gauge: the contact point moves when it touches the part, and this movement is transferred to the dial, where the pointer shows the detected variation. In practice, it is not a direct instrument for measuring an absolute dimension, but a solution for checking differences against a reference.

The 0.01 mm reading places this instrument in the category of dial gauges, making it suitable for inspections where hundredth-of-a-millimetre deviations must be detected. For this reason, it is used in comparative inspections, runout checks, flatness, parallelism, eccentricity, concentricity and in all operations where displacement must be monitored immediately.

The distinctive feature of this model is its waterproof construction, making it more suitable for workshop environments where liquids or splashes may be present. This characteristic makes it particularly interesting in harsher working conditions, helping preserve normal workshop use when the instrument is used near machine tools, workbenches or inspection stations where emulsions or coolants may be present.

From a construction point of view, the gauge is equipped with a 60 mm dial, a size that makes reading easy during daily inspections. The measuring range is 0-10 mm with 0.01 mm resolution, a widely used configuration when practical travel is required for comparative inspection while keeping the reading simple. Interchangeable threaded tips are also available, useful for adapting the contact point to the type of inspection and the geometry of the component.

From an operational point of view, the analog waterproof dial gauge is a very versatile instrument. It can be used with supports, magnetic bases, inspection fixtures and dedicated devices, making it suitable for bench inspections as well as direct checks in production. Its configuration makes it suitable when a solution more protected than a standard dial gauge is required, without giving up the classic analog dial reading.

For users looking for dial gauges suitable for more demanding working environments, this instrument represents a practical solution combining reading practicality, immediate displacement inspection and improved protection during use. It is a suitable choice when operational reliability, simple interpretation and a configuration better adapted to workshop use are required.

FAQ – Analog waterproof dial gauge

What is an analog waterproof dial gauge?
It is an instrument used to detect linear displacement and check dimensional deviations, with a configuration more suitable for environments where liquids or splashes may be present.

What is an analog waterproof dial gauge used for?
It is used to check dimensional differences, runout, eccentricity, concentricity, flatness and other very small deviations, with the advantage of greater protection during use.

What is the difference between a standard analog dial gauge and a waterproof one?
The main difference is instrument protection. The waterproof version is more suitable for working contexts where liquids, emulsions or splashes may be present.

How does an analog waterproof dial gauge work?
The contact point moves when it touches the part, and the variation is shown on the dial by the pointer, exactly like a traditional analog dial gauge.

Does the waterproof dial gauge measure an absolute dimension?
No, it is normally used for comparative inspections, therefore to check displacement against a known dimension or preset position.

What does dial gauge with 0.01 mm reading mean?
It means that the instrument has a resolution of 0.01 mm and can detect variations of one hundredth of a millimetre.

What measuring range is available?
This model has a 0-10 mm measuring range.

What resolution does this dial gauge have?
The resolution is 0.01 mm.

What is the dial diameter?
The dial diameter is 60 mm.

Can the waterproof dial gauge be supplied with interchangeable threaded tips?
Yes, interchangeable threaded tips are available on request, useful for adapting the contact point to the type of inspection to be performed.

In which environments should a waterproof dial gauge be chosen?
It is suitable when the instrument is used in workshops, near machine tools or in stations where liquids, splashes or more demanding working conditions may be present.

Can the waterproof dial gauge be used with magnetic bases and supports?
Yes, it is suitable for use with the normal support systems used in measuring stations and dimensional inspections.

For which applications is it most commonly used?
It is used in comparative inspections, adjustments, runout checks and all situations where displacement must be monitored with immediate reading.

Who is this instrument suitable for?
It is suitable for mechanical workshops, production departments, fixtures and quality control areas that need a dial gauge more protected during use.

What are the most common errors when using a dial gauge?
The most frequent errors are unstable mounting, incorrect zero setting, inconsistent contact on the part and reading interpreted without the correct reference.
