Spring driven or pneumatic driven inductive micrometer
The contacts of traditional 'pen style' probes are pushed outward under the influence of internal springs. When installed in a fixed frame, a mechanical device is required to continuously make contact between the probe and the measuring part.

On the contrary, pneumatic operation reduces the number of moving parts in the fixed frame, thereby improving reliability and reducing the cost of the fixed frame; It can also safely and quickly automatically load components into measuring tools when needed.

Inductive Micrometer | Introduction to Micrometer Performance
The touch sensitive digital probe is specifically designed for measuring delicate surfaces, such as car windshields, TV tubes, medical bottles, electric components, and plastic parts. The contact force applied by a typical probe is about 70 grams, while the light touch digital probe only weighs 18 grams when used in a horizontal position. This is achieved by replacing the traditional natural elastic rubber sleeve with a closed tolerance cover. The pneumatic type limits air leakage through the cover to 6.0 milliliters per second at 1 bar to minimize contamination of the measuring surface.

Although tungsten carbide can be installed for measuring hot glass, using replaceable nylon contacts for protection can prevent surface damage. There are also various diameters of ruby contact options for weaving steel mesh covers on cables to provide further protection, which is suitable for applications with strict contact time requirements.

For applications that require ultra-low force, the touch sensitive digital probe can be spring free (Suffix -/F) at all. Use pneumatic push/vacuum retraction to initiate forward and backward travel, but adjust the air pressure to ensure that all probes have the same contact force and remain constant throughout the entire travel. If the probe is installed vertically (with the contact at the top), the static load from the moving parts can be retracted without the need for vacuum.

Measure with a digital probe

Although digital probes are superior to LVDT/half bridge probes, it is still recommended to set standardized hosts using traditional methods. This can prevent any long-term offset or error caused by the expansion and contraction of the supporting bracket or machine.

The provided performance data includes all mechanical errors within the probe head and errors in any electronic interface module.

Absolute determination

The Solartron digital measuring probe is an absolute measuring device, which means that when opened, it will return to the correct position regardless of whether it is moved during the closed period.

Multi purpose fixed bracket

LVDT measurement probes provide optimal performance close to their zero point, requiring dedicated mounting brackets for each size of component being measured. On the contrary, digital probes can be used at any point throughout their entire stroke, allowing for the measurement of components of different sizes in a fixed frame.

technical information

Sensors convert one physical parameter (such as pressure, temperature, or position) into another parameter, typically an electronic signal. LVDT and half bridge sensors convert the motion of a core shaft within a coil magnetic field into various electronic signals. The movement of the core shaft changes the relative signal between the two windings, and LVDT (Linear Variable Difference Transformer) and half bridge are two alternative ways to reach the coil plate.
