The back plunger analog dial gauge Kafer<\/strong> is an instrument used to detect linear displacements<\/strong> and perform comparative dimensional inspections when immediate reading of deviations relative to a reference is required. It is a practical solution for workshops, tooling departments and quality control environments where it is not necessary to read an absolute dimension like with a caliper or micrometer, but rather to verify a variation, a positional difference or a very small deviation.<\/p>\n

The distinguishing feature of this model is the back plunger configuration<\/strong>. This design is particularly useful when frontal reading is less convenient or when the available space is limited and the operator needs to observe the indication from above or from a more favorable position compared to a traditional dial gauge. It is therefore an interesting solution for fixtures, supports and measuring stations where the mounting geometry makes the frontal dial less practical to read.<\/p>\n

The operating principle is the typical one of an analog dial gauge<\/strong>: the contact point moves when touching the part and the movement is transferred to the pointer, which displays the detected variation on the dial. For this reason, the dial gauge is widely used for checks of runout, alignment, flatness, parallelism, eccentricity and concentricity<\/strong>, meaning all inspections where rapid observation of dimensional variation is required.<\/p>\n

The 0.01 mm resolution<\/strong> places this model in the category of analog dial gauges<\/strong>, making it suitable for inspections where hundredth-of-a-millimeter deviations must be detected. The available configuration for this instrument includes a 0-5 mm range<\/strong>, 40 mm or 58 mm dial diameter<\/strong> and 0.01 mm resolution<\/strong>.<\/p>\n

From an operational point of view, the back plunger analog dial gauge<\/strong> is very useful when the inspection is carried out in positions where the operator does not have a direct frontal view of the instrument. In these conditions, the upper dial configuration helps make reading more immediate and can improve usability during repetitive inspections, installations on supports and controls inside dedicated fixtures. This configuration can also be advantageous when working in restricted spaces or near other elements that limit frontal visual access.<\/p>\n

This instrument represents an effective solution for users looking for an analog dial gauge<\/strong> intended for continuous technical use. It is suitable whenever readability, ease of use and a configuration better suited for installations where the upper dial improves visibility are required.<\/p>\n

Upon request, interchangeable threaded contact points<\/strong> are available to adapt the contact point according to the inspection type and the geometry of the part to be checked.<\/p>\n

    FAQ – Back plunger analog dial gauge<\/h2>\n

    What is a back plunger analog dial gauge?<\/strong>
    \nIt is an instrument used to detect linear displacements and control dimensional deviations, featuring a configuration designed for easier top reading.<\/p>\n

    What is a back plunger analog dial gauge used for?<\/strong>
    \nIt is used to inspect dimensional differences, runout, alignments and other small deviations relative to a reference, especially when frontal reading is less practical.<\/p>\n

    What advantage does the back plunger configuration provide?<\/strong>
    \nIt makes reading easier in applications where space is limited or where the dial gauge is mounted in a way that makes frontal viewing less convenient.<\/p>\n

    When should a back plunger dial gauge be chosen instead of a standard model?<\/strong>
    \nIt is recommended when the inspection is performed on fixtures, supports or workstations where the operator can read the instrument more easily from above or from a different angle.<\/p>\n

    How does an analog dial gauge work?<\/strong>
    \nThe contact point moves when touching the part and the movement is transferred to the pointer, which displays the detected variation on the dial.<\/p>\n

    What does hundredth-reading dial gauge mean?<\/strong>
    \nIt means the instrument has a 0.01 mm resolution and can therefore detect variations at the hundredth of a millimeter.<\/p>\n

    What measuring range is available?<\/strong>
    \nThis model is available with a 0-5 mm range.<\/p>\n

    What is the dial diameter?<\/strong>
    \nThe dial is available in 40 mm and 58 mm versions.<\/p>\n

    Does the back plunger dial gauge measure absolute dimensions?<\/strong>
    \nNo, it is normally used for comparative inspections, meaning to control deviations relative to a known reference.<\/p>\n

    Can interchangeable threaded contact points be supplied?<\/strong>
    \nYes, interchangeable threaded contact points are available upon request to adapt the contact point according to the inspection to be performed.<\/p>\n

    In which applications is it most commonly used?<\/strong>
    \nIt is commonly used in comparative inspections, runout checks, alignments and applications where the back plunger configuration makes deviation reading more practical.<\/p>\n

    Who is this instrument intended for?<\/strong>
    \nIt is intended for workshops, tooling departments and quality control areas looking for an analog dial gauge suitable for installations or workstations where top viewing is more convenient.<\/p>\n","protected":false},"excerpt":{"rendered":"\n\n\n\n\n
