The C.A 1725 from Chauvin Arnoux is a portable digital rotational speed meter for industrial use, enabling both non-contact and contact-based measurements. The device is designed for measuring the rotational speed of moving parts and covers a measurement range from 60 to 100,000 rpm. The precision is 10⁻⁴ L ± 6 points, ensuring reliable and accurate capture of rotational speeds in various application scenarios. The compact design with dimensions 216 x 72 x 47 mm and a weight of 250 g makes the device easy to handle and suitable for mobile use.

Applications
The C.A 1725 is suitable for a wide range of industrial applications where precise rotational speed measurement is required, such as machine monitoring, maintenance, servicing, or quality control. It can be used on motors, gearboxes, conveyor belts, machine tools, or other rotating components. The ability to measure both non-contact and contact-based significantly expands its application range, as the appropriate method can be selected based on accessibility and requirements.

Functions and Equipment in Detail
The device features a rotary switch for selecting measurement units. There are 7 selectable measurement units available, including rpm, RPM, and Hz, making the device usable in various industries and countries. Operation is performed via dedicated buttons, each assigned to a specific function such as MIN/MAX values, smoothing, or alarms for exceeded thresholds. These functions support monitoring and documentation of measurement values and enable quick response to deviations.

Technology Explained Simply
Non-contact measurement is performed optically via a reflective marker, which is attached to the rotating object. The device detects the reflection and calculates the rotational speed from the pulse frequency. For contact-based measurements, a mechanical adapter (e.g., cylinder, cone, or measuring wheel) is used, which converts the rotational motion into electrical pulses that are evaluated by the device. The digital display shows the measurement value alongside a 42-segment bargraph visually representing the current value, as well as information about set functions and alarm thresholds. This facilitates quick interpretation of measurement results.

Compatibility and Accessories
To extend functionality, various accessories are available, including FRB F connectors, reflective adhesive tape (15 pieces, each 0.1 m), a set of mechanical adapters, a USB-A / USB-B cable, and attachments (set of 3 pieces). These components allow adaptation of the device to specific measurement tasks and different object geometries.

Mounting and Installation
Mounting the C.A 1725 requires no special tools. For non-contact measurement, the reflective marker is directly attached to the rotating component. For contact-based measurements, the mechanical adapter is mounted according to the object’s geometry. Operation is performed via the rotary switch and function buttons, requiring no additional installation or configuration.

Operational Advantages
The C.A 1725 offers high flexibility through the combination of non-contact and contact-based measurement. The user-friendly operation with rotary switch and dedicated buttons reduces error susceptibility and shortens training time. The integrated display with bargraph and function indicators enables quick and intuitive interpretation of measurement values. The precision and measurement range make the device a reliable tool for precise measurement tasks in industry.
