A thermocouple consists of two wires made of different materials that, due to the thermoelectric effect, produce a voltage from which the temperature can be derived.
Depending on the desired application temperature, various thermocouples are available to choose from.
- Type J iron/cupro-nickel acc. to DIN EN 60584 & ANSI 96.1
- Type L iron/cupro-nickel acc. to DIN 43710
- Type K nickel-chromium/nickel acc. to DIN EN 60584 & ANSI 96.1
- Type K nickel-chromium/nickel acc. to DIN 43710
However, the following thermocouple types are also available from us on request:
|• Type E, R, S, and T||acc. to DIN EN 60584 & ANSI 96.1|
|• Type N||acc. to DIN EN 60584|
|• Type B||acc. to ANSI 96.1|
|• Type U||acc. to DIN 43710|
The measuring point can be manufactured as both grounded and ungrounded. You can select the classification tolerances according to class 1 or class 2.
Key features and advantages:
- Also suitable for use in higher temperature ranges, such as types B, R, and S, which are temperature-resistant up to 1600°C
- Short response time to temperature changes for fast reactions in the controlled system, especially with an ungrounded measuring point
- Robust against mechanical stress and less sensitive than, e.g., RTDs to shocks and vibrations
- Very widespread and well-known sensor type
RTDs are used to measure temperature in many sectors of industry. Here, an ohmic resistor is used as a temperature sensor. Its resistance value is temperature-dependent. Platinum has established itself as the chosen resistive material. The most frequently used platinum alloy is known as Pt100, which we manufacture according to DIN EN 60751.Other available sensor types are, for example:
|• Pt100||• Pt500||• Pt1000|
|• Ni100||• Ni120||• Various NTC sensors|
In order to minimize the effects of the cable resistances and their temperature-dependent variations, we manufacture sensors with connections for three- and four-cable circuits, as well as those with a two-cable connection.
You can select the classification tolerance according to class A and class B.
Key features and advantages:
- Higher measurement accuracy than thermocouples
- Optimum long-life stability
- High chemical resistance as a result of the platinum
Temperature Sensor Types
All sensor types can in principle be supplied as a thermocouple and an RTD.
Mineral Insulated Thermocouples/RTDs
Mineral-insulated thermocouples/RTDs, also known as sheath thermocouples/RTDs, represent a special type of temperature sensors. They consist of a flexible, thin-walled, mineral-insulated cable that allows a long service life thanks to its shock-proof construction. They differ from other temperature sensors in their compact construction, fast response times to temperature changes, and flexibility, which allows their introduction into hard-to-reach measuring points.
The materials used (1.4541 and 2.4816) mean that the sleeve welds and solders well, has optimum strength properties at high temperatures, and meets the typical requirements in environments with gaseous and liquid media.
Connectors and compression fittings are available in numerous varieties.
|• Open ends||• Connection heads|
|• LEMO connectors||• Compensation connectors|
|• Mini compensation connectors|
Numerous other connection types on request.
Frequent areas of application:
