Shockproof analog dial gauge Kafer – SA021K

The shockproof analog dial gauge Kafer is an instrument used to detect linear displacements and perform comparative dimensional inspections in workshops, tooling departments and quality control. It is used when it is not necessary to read an absolute dimension like with a caliper or micrometer, but when it is necessary to check a deviation from a reference, a positional variation or a difference between two points.

The operating principle remains that of the classic dial gauge: the contact point moves when it touches the part and this movement is transferred to the pointer, which displays the detected variation on the dial. In this model the instrument is particularly suitable for checks of runout, alignment, flatness, parallelism, eccentricity and concentricity, and for all inspections where the dimensional deviation must be monitored.

The 0.01 mm resolution places this model in the category of dial gauges, making it suitable for inspections where variations at the hundredth of a millimeter must be detected. The analog dial allows immediate reading because the operator can directly observe the movement of the pointer and quickly interpret the trend of the measurement during the inspection.

The distinguishing feature of this series is the shockproof construction. A shockproof dial gauge is particularly useful when the instrument is used in workshop environments where accidental impacts, small drops during positioning, frequent movements from one workstation to another or repetitive use on machine tools and fixtures may occur. In these situations, a shockproof version represents a more suitable choice for intensive operation compared to a traditional model.

This instrument represents an effective solution for those looking for an analog dial gauge intended for continuous technical use. It is suitable when readability, ease of use and a construction designed for normal workshop conditions are required.

The series is available with ranges of 0-10 mm, 0-30 mm, 0-50 mm, 0-80 mm and 0-100 mm. The dial diameter is 58 mm for ranges up to 80 mm, while the 0-100 mm model features an 80 mm dial. This variety allows the user to select the most suitable model according to the required travel and readability during inspection.

The 8 mm mounting shank makes the dial gauge compatible with the most common dial indicator magnetic stand, bench supports and inspection fixtures. This is important because it allows easy integration into normal measuring stations without requiring special solutions.

Upon request, interchangeable threaded contact points are available, useful for adapting the contact point according to the type of inspection and the geometry of the part to be checked. This makes the dial gauge more versatile in different applications, especially when the inspection requires different contact configurations.

From an operational point of view, the shockproof analog dial gauge is suitable for users looking for a reliable instrument for everyday comparative inspections in the workshop. It is a practical solution when immediate reading, easy mounting on supports and greater reliability in production environments are required.

FAQ – Shockproof analog dial gauge

What is a shockproof analog dial gauge?
It is an instrument used to detect linear displacements and control dimensional deviations, featuring a shockproof construction suitable for intensive workshop use.

What is a shockproof analog dial gauge used for?
It is used to inspect dimensional differences, runout, eccentricity, concentricity, flatness and other small deviations relative to a reference.

How does a dial gauge work?
The contact point moves when touching the part and the movement is transferred to the pointer, which displays the detected variation on the dial.

What does hundredth-reading dial gauge mean?
It means the instrument has a 0.01 mm resolution and can therefore detect variations at the hundredth of a millimeter.

When should a shockproof dial gauge be chosen?
It is recommended when the instrument is frequently used in workshops, on fixtures, near machine tools or in situations where accidental impacts may occur during operation.

Why is the shockproof version useful in workshop environments?
Because it is more suitable for continuous operation where frequent movements, mounting on supports and repetitive use are common.

What measuring ranges are available?
The series is available in 0-10 mm, 0-30 mm, 0-50 mm, 0-80 mm and 0-100 mm ranges.

What is the dial diameter?
The dial diameter is 58 mm for ranges up to 80 mm, while the 0-100 mm model features an 80 mm dial.

What mounting shank does the dial gauge have?
The mounting shank is 8 mm, making the dial gauge compatible with the most common dial indicator magnetic stand.

Can it be mounted on magnetic bases or supports?
Yes, the 8 mm shank makes it suitable for normal supports and measuring stations commonly used in workshops.

Does the shockproof dial gauge measure absolute dimensions?
No, it is normally used for comparative measurements, meaning to verify deviations relative to a reference value.

Can interchangeable threaded contact points be supplied?
