Chauvin Arnoux P01174830 CA 1727 speed meter incl. software content_copy

The C.A 1727 from Chauvin Arnoux is a portable digital tachometer designed for industrial use. It enables measurement of the rotational speed of moving parts both non-contact and contact-based, with a measurement range from 60 to 100,000 rpm. The device functions are designed for simple and intuitive operation, featuring a rotary switch for selecting measurement units and dedicated buttons for specific functions. Display is digital with a 42-segment bargraph, showing not only the measured value but also set functions and alarm thresholds.

Applications
This tachometer is suitable for monitoring and documenting rotational speeds in various industrial applications, such as maintenance of motors, gearboxes, pumps, or conveying systems. Non-contact measurement using reflective marks allows capturing rotational speeds without physical contact with the object, which is particularly advantageous for rotating or hard-to-reach parts. For contact-based measurements, mechanical adapters such as cylinders, cones, or measuring wheels are used to convert rotational movement into impulses detected by the device.

Functions and Equipment in Detail
The device offers a wide range of functions, including storage of up to 4,000 measurement points, automatic data acquisition, event counting, and the ability to individually program alarm thresholds and recording intervals. Recording intervals are adjustable from 10 seconds to 99,999 seconds, enabling flexible adaptation to different measurement tasks. Additional functions include MIN/MAX value display, signal smoothing, and event counting.

Technology Explained Simply
The device's precision is 10⁻⁴ L ± 6 pts, ensuring high accuracy in rotational speed measurement. Measurement is performed either optically via reflective marks glued to the rotating object or mechanically via adapters that make direct contact with the rotating shaft. The integrated memory capacity of 4,000 points allows recording of measurement data over extended periods. The USB interface enables connection to a PC to evaluate and analyze stored data using the included Tachograph software.

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 support adapting the device to different measurement conditions and objects. The reflective marks and mechanical adapters are included in the delivery scope, as well as the USB cable, Tachograph software, and user manual.

Mounting and Installation
Installation of the device requires no special mounting work. For non-contact measurement, a reflective mark is glued to the object to be measured, positioned so that the device is sufficiently exposed to the reflection signals. For contact-based measurements, the mechanical adapter is selected according to the object’s geometry and attached to the rotating shaft. Operation is performed directly on the device using the buttons and rotary switch.

Operational Advantages
The C.A 1727 offers high flexibility through the combination of non-contact and contact-based measurement. The integrated memory capacity and USB interface enable efficient data evaluation, making the device suitable for precise diagnostics and maintenance analysis. User-friendliness, achieved through clear operation with a rotary switch and dedicated buttons, reduces training time and minimizes measurement errors. The Tachograph software supports analysis of stored data on a PC, simplifying documentation and evaluation of measurement results.

Batteries are not included in the delivery scope.
