The CA 1621 from Chauvin Arnoux is a portable temperature calibrator for thermocouple sensors. The device is designed for precise measurement and simulation of temperature values on thermocouples, as well as for measurement and simulation of direct voltages in the millivolt range. It is compactly designed and intended for mobile on-site use, with simple and clear operation.

Applications

The calibrator is used in industrial measurement technology, particularly for maintenance, testing, and calibration of temperature measurement systems based on thermocouples. It is suitable for applications in process industry, power generation, manufacturing technology, and plant maintenance, where precise temperature monitoring is required. The ability to support up to eight different thermocouple types (J, K, T, E, R, S, B, N) makes the device universally applicable.

Functions and Equipment in Detail

The device enables both measurement and simulation of temperature values on thermocouples. Simulation is used, for example, to check the response of measuring instruments or controls to defined temperature values. Additionally, it can measure and simulate direct voltages in the millivolt range, which is relevant for testing measurement signals in electronic systems. The functions are accessible via an intuitive user interface.

Technology Explained Simply

The CA 1621 operates with an internal power supply based on batteries. This makes the device independent of external mains power and allows operation anywhere where no socket is available. Alternatively, it can also be operated via mains connection, ensuring uninterrupted use. The measurement and simulation functions for thermocouples are based on the conversion of temperature into electrical voltage (in mV), which is then detected or generated by the device.

Compatibility and Accessories

The device is compatible with various thermocouple types: J, K, T, E, R, S, B, N. These types differ in their material combinations and temperature ranges, with the CA 1621 supporting all eight types. These components ensure safe and efficient connection of the calibrator to measurement objects and secure transport and storage.

Mounting and Installation

The calibrator is designed as a compact, portable device and requires no mounting. It is directly connected to the thermocouples or measurement systems to be tested, with the connection made via the provided measurement leads or other suitable connection means. Installation is therefore accomplished by simply connecting to the measurement point.

Advantages in Operation

Operation of the CA 1621 is particularly flexible due to its portability and independence from mains power. The combination of measurement and simulation functions in a single device reduces the need for multiple instruments and accelerates testing and maintenance tasks. Support for eight thermocouple types increases the range of applications, and the ability to measure and simulate direct voltages in the mV range extends functionality for various application scenarios. Uninterrupted operation when powered from mains ensures reliable performance even during critical tests.
