Chauvin Arnoux P01654402 CA 1631 calibrator for process signals content_copy

The CA 1631 process signal calibrator from Chauvin Arnoux is a compact, portable measuring instrument for precise measurement and simulation of direct current signals and direct voltages. It is particularly used in industrial measurement technology and process automation, where verification and calibration of signals in field devices, sensors or control systems are required. The device is designed for mobile use and enables flexible on-site application, for example during maintenance work, commissioning or diagnostic operations in manufacturing or the energy sector.

Applications
The CA 1631 is used to measure or simulate direct current signals in the range of 0 to 24 mA and direct voltages from 0 to 20 V. These signals are typical for industrial process control, for example in the chemical industry, energy supply or process engineering. The device is suitable for checking the function of transmitters, controllers or displays by either measuring actual signals or generating artificial signals to test device response.

Functions and equipment in detail
The device features a large display area that enables clear and easy readability of measurement values. The operation is designed to be simple, ensuring quick and safe handling even in limited space or under difficult environmental conditions. Measurement of direct current is performed with an accuracy of 0.015 %, providing high precision for calibration and testing purposes. Measurement of direct voltage is performed with an accuracy of ± 0.02 %, which is also sufficient for precise applications.

Technology explained simply
The CA 1631 operates as a process signal calibrator, functioning both as a measuring instrument and a signal generator. It generates direct current signals in the range of 0 to 24 mA, which corresponds to the standard for industrial 4-20 mA loops. Direct voltages in the range of 0 to 20 V can also be simulated or measured. The accuracy of 0.015 % for current signals and ± 0.02 % for voltages ensures reliable calibration. The device is battery-operated and independent of mains power, making it suitable for use in locations without electrical supply. Alternatively, it can also be operated via mains connection, enabling uninterrupted operation.

Compatibility and accessories
To extend functionality and adapt to various connection types, various accessories are available. These include test leads with 4 mm straight/angled plugs, suitable for CAT IV-1000 V, as well as alligator clips CAT IV-1000 V 15 A for flexible connections. For precise measurements on small contacts, test probes 4 mm / 4 mm socket CAT II 300 V are available. For transport and storage of the device, a transport case with dimensions 120 x 245 x 60 mm is available. Additionally, 10 pcs. fuse flink 125 mA (250 V / 5x20 mm) are available as replacement fuses.

Mounting and installation
The CA 1631 is designed as a portable device and does not require mounting. It is directly connected to the devices to be tested, with the connection made via the provided terminals. Operation is performed via buttons and the display area, without requiring additional software or external devices.

Advantages in operation
Operation of the CA 1631 is simple and requires no special preparation. The combination of battery and mains operation enables flexible use. The high accuracy and compact design make the device a reliable tool for technical personnel who need to perform precise measurements and simulations on site. The use of standardized connection types (4 mm plugs) ensures universal compatibility with common measuring and testing equipment.
