The item from Chauvin Arnoux, manufacturer number P01174903, is a set of three replacement adapters for the mechanical adapter set (P01174902), specifically developed for use with rotational speed measuring devices. These adapters are designed for precise measurement of rotational speeds on shafts and axles, as well as for determining linear speeds in linear movements, for example on conveyor belts. The components are designed as replacement parts to maintain or extend the functionality of the original adapter set, especially when the original adapters are worn or damaged.

Applications

The adapters are intended for industrial and technical applications where mechanical contact measurement is required. The conical adapter is suitable for shaft ends with a minimum diameter of 5 mm, with the conical shape ensuring a secure and slip-resistant connection. The cylindrical adapter is suitable for shafts or axles with a diameter greater than 5 mm, as well as for flat surfaces, thereby enabling broader application possibilities. The measuring wheel is used to determine linear speeds, for example on conveyor belts or other linearly moving components, thus enabling monitoring of transport or production processes.

Functions and Equipment in Detail

The set consists of three clearly defined components: a conical adapter, a cylindrical adapter, and a measuring wheel. The conical adapter is designed for shaft ends with a minimum diameter of 5 mm to ensure a secure mechanical connection. The cylindrical adapter offers more universal application, as it can be mounted on axles with a diameter greater than 5 mm or on flat surfaces. The measuring wheel has a diameter of 31.83 mm and a circumference of 10 cm ± 0.1 mm, enabling precise measurement of linear speeds. The precision of the circumference is critical for the accuracy of speed measurement, as any deviation directly affects the measurement results.

Technology Explained Simply

The adapters operate mechanically through direct contact with the surface to be measured. For rotational speed measurement, the adapter is placed onto the rotating shaft or axle, thereby transferring the rotational movement to the measuring device. In contrast, the measuring wheel is placed onto the linear surface to be measured; the number of wheel rotations is recorded by the measuring device and converted into speed based on the known circumference. The accuracy of the measurement depends on the mechanical fit and the surface condition. The design of the adapters ensures a stable and slip-resistant connection to avoid measurement errors due to slippage.

Compatibility and Accessories

The replacement adapters are specifically designed for the mechanical adapter set (P01174902) and are compatible with the tachometer models CA 1725 and CA 1727. The adapters are intended as replacement parts to maintain the functionality of the original adapter set.

Mounting and Installation

Installation is performed by directly placing the adapters onto the respective measurement points. The conical adapter is fitted onto the shaft end, the cylindrical adapter onto axles or flat surfaces, and the measuring wheel is placed onto the linear surface to be measured. The connection is purely mechanical, without additional fastening elements. Correct positioning is crucial for measurement accuracy.

Advantages in Operation

The replacement adapters allow continuous use of the rotational speed meter, even if the original adapters are worn. The precise fit and defined dimensions ensure reliable measurement results. The variety of adapter shapes expands application possibilities and enables measurement on different surfaces and shaft geometries. The mechanical contact measurement provides a simple and robust method that requires no additional power supply or complex installation. Compatibility with models CA 1725 and CA 1727 ensures direct interchangeability without modifications to the measuring device.
