General
Tolerance class	2

The K-thermocouple probe with needle shape and stainless steel sheath from Chauvin Arnoux is a specified sensor for precise temperature measurements in industrial and laboratory applications. It is particularly suitable for point insertion measurements, where high spatial resolution and fast response are required. The probe features a robust stainless steel sheath, making it suitable for use in confined spaces and under mechanical stress.

Applications

The probe is designed for applications requiring accurate temperature measurement at a defined point, such as process monitoring, quality control, or material testing. The combination of compact design and high response speed makes it especially suitable for dynamic measurement tasks where rapid temperature changes must be detected.

Functions and Features in Detail

The probe is based on K-thermocouple technology, which relies on the thermoelectric voltage generated between two different metals. It enables measurement in the range of -50 °C to 800 °C, with tolerance class 2 defining accuracy according to IEC 60584-1. The response time at 63 % is 1 second, ensuring fast reaction to temperature changes. The stainless steel sheath with a diameter of 3 mm and a length of 15 cm provides mechanical stability and thermal conductivity, essential for precise measurement.

Technology Explained Simply

The K-thermocouple technology uses the Seebeck effect, where a temperature difference between two metal junctions generates an electrical voltage. This voltage is converted into a temperature value. Tolerance class 2 means the deviation from the actual value remains within specified limits, which is sufficient for industrial applications. The compensated miniature connector ensures a reliable electrical connection and minimizes errors caused by thermal influences at the connection point.

Compatibility and Accessories

The probe is compatible with various measuring instruments from Chauvin Arnoux, including thermometers C.A 1821, C.A 1822, TK 2000, TK 2002, and data logger L642. It can also be used as an accessory for multimeters, provided a suitable adapter is available. As an alternative, the SK20 flexible probe is offered, which has a smaller measurement range (-40 °C to +450 °C) and a smaller sheath (1.5 mm diameter), but offers a longer probe length (1 m).

Installation and Mounting

Installation is performed by inserting the probe into the medium to be measured. The needle shape allows for precise positioning, and the 15 cm length is sufficient to penetrate many materials or liquids. Connection to the measuring device is made via the integrated miniature connector, which is directly plugged into the corresponding inputs of compatible devices.

Operational Advantages

The probe is characterized by high mechanical robustness, fast response time, and a wide temperature measurement range. The stainless steel sheath offers corrosion resistance and thermal conductivity, enhancing measurement accuracy. Use with standardized Chauvin Arnoux devices ensures easy integration into existing measurement systems.

Scope of Delivery

The scope of delivery includes 1 x K-thermocouple probe (needle probe) and 1 x user instructions.
