Rating of the best gap gauge sets for 2022

In the in-line production process of products, it is not possible to manually check each part. Therefore, the accuracy of working machines should minimize the risk of defects. In the past, manually setting the desired location of milling or turning heads was often ignored due to the hassle of such an exercise. However, this attitude is now unforgivable. As a result, special devices play a special role in the production process when adjusting and setting up equipment - probes for measuring gaps. In addition, they are of great importance when servicing cars, when it is necessary to adjust spark plugs, valves or other parts.

What it is

The measuring probe is a device for contact measurement of small distances.

Represents a set of perfectly polished thin plates, differing in thickness, with applied dimensions and enclosed in a holder. They are usually made from brass or stainless steel. Nickel plating provides additional anti-corrosion properties. Most belong to the 2nd class of accuracy, but there are high-precision 1st class.

Mainly used for internal measurements:

• when adjusting valves and bearings;
• for selection of gaps in spark plugs;
• for equipment alignment;
• half-coupling openings;
• to clarify the distance between the piston groove and the ring;
• to determine the "soft foot" by inserting a probe into the space between the foot and the foundation.

Device

The design is quite simple and consists of a set of calibration elements. All plates are connected in a cage with a hinged lock, which allows replacement if necessary.

What are

The standard provides for the production of seven sets (No. 1 - No. 7), which differ in the number of plates and their dimensions. Usually the thickness is 0.03-1.0 millimeters with a length of 5, 10 and 20 centimeters.

Thickness difference:

• 0.03-1.00 - 0.01 mm;
• 0.1-1.0 - 0.05 mm.

The thickness value is printed on each plate.

Standard Ingredients:

Deep gaps are measured with gauge wedges, which can be:

• Wedge - measurement of distances up to 9 mm with an accuracy of 0.1. Used with a slider that slides over the surface. In its absence, paint is applied to determine the gap in the painted areas.
• Cylindrical.
• Digital - with the function of displaying numerical values ​​on the monitor, which is very convenient for equipment alignment.

In addition, modern models are:

• turnouts;
• star-shaped;
• straight;
• ceramic with a hemisphere;
• with disc tip;
• pointed;
• elongated;
• curved.

How to use

In order to measure the gap between two surfaces, one or more calibration plates from the kit must be inserted into it in turn or simultaneously. As soon as they completely fill the space, their thickness will be equal to its distance. At the same time, they do not have free play, and they should not fall through, but move with little effort.

• high accuracy;
• universality;
• ease of use without the need for special skills and abilities.

During the measurement process, the probe is brought to the workpiece, and not vice versa!

Criterias of choice

In order not to make mistakes when choosing, you need to pay attention to the following characteristics:

1. The thickness of the elements. With a total thickness of 1 mm, the thickness of the individual plates differs in increments of 0.01-0.05. The error depends on the thickness of one element - as it increases, the accuracy decreases. Many of the best manufacturers indicate the value in millimeters, but some foreign models are characterized by an inch measuring system.
2. Working length - some measurements may require a specific value.
3. The number of probes in the set.The number of calibration elements with different thicknesses ranges from several pieces to 20 probes. The choice is made depending on the type of work planned for execution.

Where could I buy

Popular models are bought in building supermarkets or stores that offer tools and fixtures for various measurements. Consultants will be happy to give recommendations and advice - what tools are there, how to choose, which company is better to buy, how much it costs.
