Chauvin Arnoux P01174902 Set of mechanical adapters content_copy

The accessory kit for tachometers from Chauvin Arnoux extends the functionality of the devices C.A 25, C.A 27, C.A 1725 and C.A 1727. It is designed for precise measurement of rotational speeds on shafts and axles, as well as for determining linear speeds, for example on conveyor belts. The kit is designed for a maximum rotational speed of 10,000 min-1 and consists of an adapter and three specific attachments that can be exchanged depending on the application.

Applications
This accessory is designed for use in industrial and technical environments where precise rotational speed and speed measurements are required. It enables measurement at shaft ends, axles and flat surfaces, as well as determination of the linear speed of linearly moving parts. Application areas include, among others, machine maintenance, drive system servicing and monitoring of conveyor systems.

Functions and equipment in detail
The kit includes an adapter that connects the tachometer to the individual attachments. The conical attachment is suitable for shaft ends with a minimum diameter of 5 mm and ensures a secure, non-slip connection. The cylindrical attachment is suitable for shafts or axles with a diameter over 5 mm as well as for flat surfaces, thus ensuring broader applicability. The measuring wheel is used for measuring linear speed; it has a diameter of 31.83 mm and a circumference of 10 cm ± 0.1 mm, enabling high accuracy in speed determination.

Technology explained simply
The maximum permissible rotational speed of 10,000 min-1 represents the upper limit for safe use of the accessory. The precise calibration of the measuring wheel with a circumference of 10 cm ± 0.1 mm ensures high measurement accuracy when determining linear speeds. The mechanical design of the attachments ensures a stable and non-slip connection with the components to be measured, increasing the reliability of measurement results.

Compatibility and accessories
The accessory kit is specifically developed for tachometers C.A 25, C.A 27, C.A 1725 and C.A 1727. It is not intended for other devices, as the adapter design is tailored to these models. The combination of different attachments allows flexible adaptation to various measurement objects without requiring additional tools or adapters.

Installation and mounting
Mounting is done by simply inserting the attachments into the adapter, which is then attached to the tachometer. The connection is mechanically stable and does not require additional fastening elements. The selection of the appropriate attachment depends on the geometry of the object to be measured – conical for small shafts, cylindrical for larger axles or flat surfaces, and the measuring wheel for linear movements.

Advantages in operation
The variety of attachments significantly extends the application range of tachometers. The precise calibration of the measuring wheel and the mechanical stability of the attachments ensure reliable and reproducible measurement results. The simple handling and quick exchange of attachments reduce measurement time and increase efficiency during maintenance and servicing activities.

Scope of delivery
The kit includes the adapter, the conical attachment, the cylindrical attachment and the measuring wheel. Delivery is made in the described composition, without additional elements.
