Dial thermometers work on the bimetal, expansion or gas actuation principle. This enables scale ranges of -200 to +700 °C in different class accuracies, response times and resilience to environmental influences. Diverse connection designs, stem diameters and individual stem lengths enable a flexible measuring location design. Dial thermometers with remote capillaries are particularly versatile. All thermometers are suited for operation in a thermowell if necessary.

Thermocouples are temperature sensors that generate a voltage directly dependent on temperature. Compared to resistance thermometers, they are particularly suited for high temperatures up to 1,700 °C. Instrument designs from mineral-insulated sheathed cable are very resistant against extremely high vibration loads (depending on instrument model, sensor element and wetted materials). The accuracy classes 1 and 2 apply for thermocouples in accordance with IEC 60584 as well as the standard and special classes in accordance with ASTM E230.
Industrial assembly
Thermocouples in this series can be combined with a large number of thermowell designs. Use without a thermowell is permitted when using a fixed (welded) fitting.
Reference:
The measuring inserts per DIN 43735 for resistance thermometers described here are designed for installation in a protective fitting. Operation without thermowell is only recommended in certain applications. The measuring insert is made of a bendable mineral-insulated sheathed cable.

Thermocouples of this series are designed for fitting into vessels and pipelines. Standard flanges to DIN EN or ASME are available. These temperature sensors are suitable for liquid and gaseous media under moderate mechanical load.
Reference:
Temperature transmitters convert the input signal from a wide range of sensors, such as resistance sensors and thermocouples, but in some cases also from potentiometers, into a standardised output signal (e.g. 0 … 10 V or 4 … 20 mA). With digital temperature transmitters, the sensor type and the measuring span can be freely configured, along with many further options such as the error signalisation or a measuring location identification.
These temperature transmitters are designed for universal use in plant and machine building, and also in the process industry. They offer high accuracy and excellent protection against electromagnetic influences (EMI). Via the WIKAsoft-TT configuration software and the model PU-548 programming unit, the model T15 temperature transmitters can be parameterised very easily, quickly and with a clear overview.
