DataMet BIG DEPTH 3-point internal micrometer set

Description

PRODUCT

The BIG DEPTH DataMet 3-point internal micrometer SET is an Industry 4.0-ready set for measuring internal diameters deep inside long bores. Each set combines a DataMet computerized 3-point internal micrometer with sub-micron resolution of 0.0001 mm, interchangeable measuring heads for its range, setting rings and an extension system for the selected maximum depth. A calibration certificate ISO/IEC 17025 (ILAC MRA) is included.

• 20–50 mm: 4 measuring heads, 2 setting rings; maximum depth 1000 mm or 2000 mm
• 50–100 mm: 2 measuring heads, 1 setting ring; maximum depth 1000 mm, 2000 mm or 3000 mm
• 100–250 mm: 2 measuring heads, 1 setting ring; maximum depth 1000 mm, 2000 mm or 3000 mm
• Resolution 0.0001 mm on all versions; Wireless + USB data output

Because the setting rings are part of the set, the instrument is zeroed directly against a reference of known size before measuring, and the full range of the set is covered by the supplied heads without additional purchases.

COMPUTERIZED MICS / DataMet FUNCTIONS

The DataMet system provides integrated measurement, visualization, tolerance control and data-management functions directly on the instrument:

• Go/NoGo tolerance evaluation against set limits
• Max/Min capture for finding the largest and smallest diameter in a section
• Formula and Timer functions
• Linear correction and Temperature correction
• Resolution selection
• Connection indication
• Memory for 2000 values organised in folders, with Statistics mode and memory data transfer
• Rechargeable Li-Pol battery, charging via USB-C

CONNECTIVITY & DATA

• Built-in connectivity: Wireless and USB data output on every version of the set.
• Software: MICROTECH software is available as a free download for receiving and processing measurement data on a PC.
• Data-transfer modes: single readings can be sent live during measurement, or values stored in the instrument memory can be transferred afterwards.

When the measuring head is several metres inside the part, the operator does not have to read a display at the bore entrance: the result is transmitted to a PC, which removes manual transcription of readings taken at different depths.

WHAT PROBLEM DOES IT SOLVE?

• Restricted access at depth: conventional internal micrometers measure near the bore entrance only. Extensions up to 1000, 2000 or 3000 mm bring the 3-point head to the measuring section inside long parts.
• Centring in the bore: with a two-point instrument the operator has to search for the true diameter by rocking the gauge, which is impractical at depth. Three contact points centre the head automatically and give a stable reading.
• Reading the result remotely: wireless and USB output deliver the value to a PC, so the result does not depend on viewing a display inside or at the mouth of a deep bore.
• Repeated data entry and tolerance checks: Go/NoGo, Max/Min, memory and statistics evaluate and record series of measurements along the bore without manual notes.
• Traceable zero: the supplied setting rings and ISO/IEC 17025 calibration certificate provide a defined reference for every measurement.

HOW DOES IT WORK?

The operator fits the measuring head for the required diameter and sets the instrument to zero on the matching setting ring. The required extension length is then assembled, and the head is inserted into the bore up to the measuring section.

The three measuring contacts are brought into contact with the bore wall, centring the head on the bore axis. The DataMet electronics display the diameter with 0.0001 mm resolution, compare it with the set tolerance limits and can capture maximum and minimum values. Each result is stored in memory or transferred via Wireless or USB to the PC software. Repeating the measurement at several depths and angular positions shows how the diameter changes along the bore.

WHERE IS IT USED?

• Hydraulic and pneumatic cylinders: bore diameter checked at several positions along the cylinder length; the depth extensions reach the middle and far end of the tube, and Max/Min reveals taper or wear zones.
• Long sleeves and bushings: internal diameter deep inside the part, where the 3-point head centres itself without operator rocking.
• Hollow shafts and deep-bored parts: diameter of bores drilled or bored over 1000 mm and more, measured at the actual working section instead of only at the entrance.
• Small deep bores from 20 mm: the 20–50 mm set with 4 heads covers narrow long holes at depths up to 2000 mm.
• Series inspection of long parts: readings at multiple depths are stored in folders and transferred to a PC, giving a documented diameter profile for each part.

CONFIGURATION & CUSTOMIZATION

The set is selected by diameter range and by maximum measuring depth:

• 20–50 mm: 4 measuring heads and 2 setting rings for small bores; depth 1000 mm or 2000 mm.
• 50–100 mm: 2 measuring heads and 1 setting ring; depth 1000 mm, 2000 mm or 3000 mm.
• 100–250 mm: 2 measuring heads and 1 setting ring; depth 1000 mm, 2000 mm or 3000 mm for large cylinders and housings.

Standard configuration: DataMet 3-point internal micrometer with 0.0001 mm resolution, measuring heads and setting rings for the range, extension for the chosen depth, Wireless + USB output and ISO/IEC 17025 calibration certificate. Choose the shortest depth that reaches the measuring section of your parts: a shorter assembly is easier to handle, while 3000 mm versions cover the longest bores.
