General
Mains operation

The CA 1623 from Chauvin Arnoux is a portable temperature calibrator for resistance sensors, specifically designed for measuring and simulating resistance thermometers. The device enables precise calibrations and inspections on-site and is suitable for mobile applications due to its compact design and easy operation. It supports work with up to seven different types of resistance sensors, including Pt10, Pt50, Pt100, Pt200, Pt500, Pt1000, and Pt100 JIS, and can perform both measurements and simulations. The resistance generation function allows defined resistance values to be simulated, which is useful for testing measurement systems or calibrating sensors.

Applications

The calibrator is designed for technical inspections and maintenance work in the field of temperature measurement. It is particularly used in industry, for maintenance of measurement systems, or in manufacturing, where precise calibration of resistance thermometers is required. The support for various thermometer types makes it flexible to use, regardless of the exact sensor type. Mobile use is enabled by battery operation, allowing the device to be used even in locations without direct power supply.

Functions and Equipment in Detail

The device allows both the actual temperature of a resistance sensor to be measured and its electrical resistance value to be simulated. These functions are especially important for validating measurement chains, where the accuracy of the sensor or the subsequent evaluation unit must be checked. Simulating resistance values enables testing the behavior of measurement systems under defined conditions without requiring a physical sensor. Operation is via an intuitive interface, ensuring quick and error-free input.

Technology Explained Simply

The CA 1623 operates with an internal power supply using batteries, allowing it to function independently of mains power. If required, it can also be connected to the mains to ensure continuous use without interruption. Measurement and simulation are performed based on the electrical properties of resistance sensors, which rely on a defined resistance value correlated with temperature. Support for the Pt100 standard, which is standard in many industrial applications, as well as the JIS variant, common in Japan and other regions, demonstrates the device’s international applicability. The resistance generation function enables precise resistance values to be simulated, which can then be detected by a measuring device or system.

Compatibility and Accessories

The device can be combined with various accessories to extend its application. These include test leads with 4 mm connectors (straight and angled), ensuring secure connections, as well as crocodile clips and test probes, providing flexible connection options at different measurement points. The test leads are rated for CAT IV-1000 V and are therefore suitable for use in high-voltage environments. A transport case is also available to safely transport the device and protect it from damage.

Mounting and Installation

The CA 1623 is designed as a handheld device and requires no mounting or installation. It is simply picked up and started via the control interface. The connection leads are attached to the corresponding measurement points, with the use of suitable accessories such as crocodile clips or test probes enabling adaptation to various connection types.

Operational Advantages

The combination of portable design, battery operation, and support for various resistance thermometer types makes the CA 1623 a flexible tool for mobile calibrations. The ability to both measure and simulate reduces the effort required for testing measurement systems. Independence from mains power allows use in locations without fixed power supply, and continuous operation when connected to mains ensures uninterrupted work. The simple operation reduces error susceptibility and shortens working time during maintenance and inspections.
