Dial gauges are mechanical measuring instruments which are used with the highest levels of precision for different measurements. dk Fixiersysteme offers various dial gauges with a measuring range from 0.1 to 10 mm.

Dial gauges have been used as mechanical measuring instruments since the end of the 19th century to measure lengths or length differences as precisely as possibly. Nowadays, dial gauges are used for exact measurements in numerous areas. The main area of application is the industrial sector, where measuring technology is a key priority with regard to quality assurance. However, measuring instruments in the form of dial gauges are being used more and more in research and development.

With a mechanical dial gauge, the linear movement of a pin is translated into the rotary movement of a pointer via an internal mechanism. With the aid of a gear rack and a transfer pinion, it is possible to achieve a level of precision of up to one thousandth of a millimetre when reading the dial gauge. So that precise measuring results could be guaranteed with different dial gauges, a DIN standard was introduced for the German dial gauge industry. According to DIN 878, all dial gauges made and sold in Germany must have an indicator which can rotate through 360 degrees. Furthermore, a consistent scale regulation applies to all dial gauges so that there is no risk of deviations with regard to readability.

There are two types of dial gauge. Traditional dial gauges include analogue dial gauges which work mechanically. They are characterised by a round dial on which the measurement can be read with the help of a scale division. The gauging force is nearly always constant by several measuring procedures as the dial gauge features a built-in spring. No batteries are required for analogue dial gauges, unlike with the second type – digital dial gauges. This means that with regular maintenance, they can be used without any problems for several decades without losing their precision.

Digital dial gauges have an integrated battery which supplies the display, as well as other parts of the measuring instrument with power. The user profits from the operating ease and readability of the digital display. What’s more, the internal memory means that measured distances can be read precisely and several decimal places can be displayed or rounded correctly.


A dial gauge is made up of numerous components which work together to ensure the gauge works properly. The externally visible individual parts are the probe, the measuring pin, the clamping shaft and the scale. The scale has two functions: it shows the measured numerical values for reading and also can be used to set the measuring instrument. There is usually a rotatable outer ring around the circumference of the scale which can be used to adjust the zero point. The advantage of this is that it is possible to measure several size differences.

To be able to ensure a reading which is as precise as possible, dial gauges are equipped with a precise scale and the specified scale division values. So that the pointer can actually move, the longitudinal movement of the measuring stylii is transferred to the pointer by a precise rack and pinion mechanism. As a result, the dial gauge indicator can make several full rotation. An additional, smaller pointer ensures that the number of rotations is indicated.

The laterally moving pin which holds the stylii is constantly under pressure from an internal spring, which applies the same thrust irrelevant of whether the pin moves in or out. When the object being measured is removed, the spring ensures that the pin, and the connected pointers return to the start position.

Dial gauges from dk:

The dk product range includes the following dial gauges:


Analogue precision dial gauges (DIN 878) are available in three different versions. All versions feature a housing diameter of 58 mm. The models also boast interchangeable M2.5 stylii and an Ø8 mm clamping shaft. In addition to the standard version, dk Fixiersysteme also offers a premium version with an extremely long service life. One of the versions features impact protection to ensure the precision of the dial gauge display, even with robust use.

Precision indicators (DIN 879-1) have a housing diameter of 62 mm and also boast interchangeable M2.5 stylii as well as an Ø8 mm clamping shaft. dk offers two versions of precision indicator. The standard version is equipped with spindle release and impact protection. The second version is also water-tight.

Lever gauges (DIN 2270) are ideal for measurements which are carried out in testing areas which are not easily accessible. The movable stylii eases the measuring process considerably. With a housing diameter of 32 mm, lever gauges have a rather small dial compared to other dial gauges. Nevertheless, they are resistant to impacts as they are fitted with a friction coupling. dk offers lever gauges with a measuring range of 0.8 or 0.2 mm.
