Type K

Nickel chromium-nickel (NiCr-Ni)

The colour of the outer sheath is green, the positive wire is also green and the negative wire is white. Thermowires for connection to type K elements are labelled with KX. Compensating wires are marked with KC or for further differentiation with KCA (0 °C to +150 °C) and KCB (0 °C to +100 °C).

Temperature sensor type K – robust and universal use of a thermocouple

The most widely used thermocouple is the type K temperature sensor. The corresponding characteristic curve or input can be found on almost every standard measuring device.

The type K thermocouple can be used universally because of its robustness and small design. Whether in industry, development or in the laboratory. The measuring point is welded insulated as standard, so that the measurement evaluation cannot be falsified by superimposing offsets.

Sheathed thermocouples type K can be bent freely over their entire length. This allows the thermocouple to be integrated into the installation site. The temperature to be measured can therefore be recorded close to the desired measuring point. A possible connection cable allows easy routing up to the measured value acquisition. There is a choice of element diameter, element and cable length as well as the type of connection configuration (plugs, sockets, bare cable ends, etc.).

Type K thermocouples are often also manufactured as cable sensors. Here, the actual type K thermal line serves as a measuring sensor. The two wires on one side are welded to form a measuring tip. The second end goes into the gauge. A type K compensating line, on the other hand, is less suitable as a cable sensor, as it outputs a false type K thermal voltage from 200 ° C and thus the measurement is unusable.

You can find a large selection of type K thermocouples in our online shop, the professional shop for sensors and thermocouples.

The sheathed thermocouples from Therma Thermofühler GmbH are ideally suited for many applications not only because of their robustness. The fact that they can be used universally due to their small dimensions (diameter of 0.25 mm are also available) and flexibility makes them the number 1 choice for many professional users.

Our quality type K thermocouples are used very often. You can find a wide variety of these in our professional online shop at particularly good conditions. In addition to different probe diameters – whether for very fast measurements, the smallest outer diameters, medium diameters with high temperature resistance or large diameters with a sluggish response time – you can configure your desired thermocouple by selecting additional properties. Select the element length (50 mm to 1,000 mm), the cable length (500 mm to 5,000 mm), the connection type (with free ends, mini connector, standard connector, Lemo connector, Lemo coupling) and the cable type (Teflon , Fiberglass, silicone). Of course, we can also offer other individual solutions on request.

The universal thermocouple type K

Just like other thermocouples, the type K temperature sensor makes use of the thermoelectric effect to enable accurate measurement results even at particularly high and particularly low temperatures. With thermocouples, different metals are used as conductors or semiconductors, which ensure suitability in certain temperature ranges due to the respective material combination. This makes it possible to measure at temperatures above 1000 ° C – as often occurs in the industrial sector – and to obtain the lowest possible deviation. The type K thermocouple is also in great demand because it covers a wide temperature range in which reliable measurements can be made. A temperature of 750-1100 ° C often occurs in industry, development and the laboratory, which is why the thermocouple K is one of the most commonly used temperature sensors.

Type K thermocouple – marking and marking

The K type thermocouple can be easily recognized by the color coding of the outer sheath and the conductor. The green outer sheath is characteristic here, just like the green positive conductor and the white negative conductor. For the installation it is important to note that the extension cables of the type K thermocouple are marked with the letter KX, while the compensating wire of the type K thermocouple can be identified by the KC mark. Additional specifications for the type K compensating cable are also possible through further letter combinations. If you want to know why the type K thermocouple can be found in almost every standard measuring device, you will not only see the answer in the temperature range that the thermocouple covers. Finally, type N, R & S thermocouples can be used in similarly high temperature ranges.

Structure and construction of the extension cable type K

In addition to the practical coverage of a relatively large temperature range, the type K temperature sensor is also very popular due to its design. The construction is comparatively small, but still robust and therefore suitable for many locations in the industrial or scientific field. The sheathed thermocouple is insulated and welded according to current standards and thus allows an unadulterated measurement value evaluation. The possible uses of type K thermocouples are all the more flexible thanks to the combination of the small design with the extremely flexible combination of materials. The nickel-chromium-nickel sheathed thermocouple type K can easily be bent along its entire length without being damaged. Integration into existing systems is particularly easy and the type K thermocouple fits ideally into small spaces.

Buy type K thermocouples and lay them very easily

Integrating temperature sensors can be tricky, especially when the thermocouples are delicate and inflexible. With the type k thermocouple, this is not a problem thanks to its high degree of flexibility. A connection cable for the NiCr Ni thermocouple can also be easily attached to the point where the measured values ​​are recorded. The type K thermocouple remains flexible in the case of specifications that go beyond the basic construction and allows an individual selection of element diameter and length, as well as the cable length and the connection configuration. Regardless of whether you want to connect the nickel-chromium-nickel thermocouple to bare wire ends using a plug – you will easily find the right place thanks to the light, yet robust design. Simply contact us for non-binding advice on the type K thermocouple or our other products.

The number one for temperature measurement -Thermocouple type K

No wonder that the temperature sensor NiCr Ni type K shines with so many applications. The powerful measuring instrument is available in diameters as small as 0.25 mm as well as in many other versions in our online shop. The type K thermocouple can also be manufactured as a cable sensor. The actual thermal line is then used as a measuring sensor and the two cables are welded together to form a measuring tip. After connecting the second end to the measuring device, the type K cable sensor can be used. In our professional shop you can get advice on your thermocouple needs and are guaranteed to get the right product for your laboratory or production conditions. Our high-quality temperature sensors have different connection types and cable types, so that a precisely fitting device can be found for every area of ​​application.
