Shockproof and waterproof analog dial gauge Kafer – SA021KW

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

The operating principle is the typical one of a dial gauge: the contact point touches the part, moves linearly and transfers the movement to the pointer, which displays the detected variation on the dial. For this reason, the dial gauge is widely used for inspections of runout, alignment, flatness, parallelism, eccentricity and concentricity, meaning all checks where dimensional variation must be observed.

The 0.01 mm resolution places it in the category of analog dial gauges, making it suitable whenever hundredth-of-a-millimeter deviations must be highlighted. The analog dial provides immediate reading and helps the operator follow the pointer movement during inspections, particularly in repetitive checks and adjustments.

The special feature of this version is the combination of shockproof structure and waterproof construction. This makes the dial gauge more suitable for harsh working conditions than a standard model, especially when the instrument is used in environments exposed to accidental impacts, frequent movements, presence of liquids, sprays, emulsions and coolants. In practice, it is an excellent solution when the instrument must be protected both mechanically and during everyday workshop use.

From a practical point of view, these dual characteristics are particularly useful near machine tools, in production departments and in situations where the dial gauge does not remain fixed on a protected bench but is used in demanding operating conditions. In these cases, a shockproof and waterproof instrument helps maintain greater reliability and continuity during use.

The series is available with 0-10 mm and 0-30 mm ranges, both featuring a 61.5 mm dial diameter. This configuration allows the user to select the most suitable version according to the required travel while maintaining good readability during inspection.

Upon request, interchangeable threaded contact points are available to adapt the contact point according to the inspection type 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 and waterproof analog dial gauge is intended for users looking for an analog instrument suitable for everyday comparative inspections, with greater protection compared to a traditional model. It is a practical solution whenever immediate reading, robustness and ease of use are required in workshop environments.

FAQ – Shockproof and waterproof analog dial gauge

What is a shockproof and waterproof analog dial gauge?
It is an instrument used to control linear displacements and dimensional deviations, featuring a structure designed for harsh operating conditions.

What is a shockproof and waterproof 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.

What is the difference compared to a standard dial gauge?
This version combines shockproof protection and waterproof construction, making it more suitable for frequent workshop use and environments where liquids or sprays may be present.

When should a shockproof and waterproof dial gauge be chosen?
It is recommended when the instrument is frequently used in production, near machine tools or in workstations where accidental impacts and contact with liquids may occur.

Why is the shockproof version useful?
Because it makes the dial gauge more suitable for intensive operation, with frequent movements and higher stresses during use.

Why is the waterproof construction useful in workshops?
Because it helps make the instrument more suitable for environments where sprays, emulsions or coolants may be present.

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

What is the dial diameter?
The dial diameter is 61.5 mm.

Does the dial gauge measure absolute dimensions?
No, it is normally used for comparative inspections, meaning to read deviations relative to a known reference.

Can interchangeable threaded contact points be supplied?
Yes, interchangeable threaded contact points are available upon request to adapt the contact point according to the type of inspection to be carried out.

In which applications is it most commonly used?
It is commonly used in comparative inspections, adjustments, runout checks, alignments and repetitive dimensional inspections in workshops.

Who is this instrument intended for?
It is intended for workshops, tooling departments, production areas and quality control departments looking for an analog dial gauge more suitable for demanding operating conditions.

What are the most common errors when using a dial gauge?
The most common errors include unstable mounting, incorrect zero setting, improper contact on the part and interpretation without a correct reference.
