eXacal technology
eXacal precision thermometers were designed from scratch. The development time took over four years. All the components used were carefully designed and coordinated with each other. The developed handle, which functions as a technology provider, is of particular importance. Thanks to its modular design, eXacal thermometers can be combined in almost any way.
The handle as a technology support
Our eXacal thermometers can be assembled as a modular system in almost any way. This is made possible by our aluminium handle, which is assembled with an individually 3D-printed insert for each thermometer. Important components such as strain reliefs, inert gas fillings or different protection tubes can thus be freely combined.
Temperature detectors
from our own manufactory
For the thermometers, we use wire-wound Pt100 ceramic resistors as the temperature detector. They are handmade and carefully stabilised. Three hand-picked types are used. They each represent the best compromise between design, stability, hysteresis and self-heating:
Thermometer wire
For the thermometer wire at the temperature detector and in the capillaries we use noble metals and no commercial sheath wires. Depending on the temperature range, these are pure silver or platinum. In this way we reduce thermoelectric effects and reduce inherent voltages in the thermometer.
Protection tubes
Protection tubes are selected with respect to thermal stress and the condition of the atmosphere. In order to optimally protect the temperature detector from mechanical and chemical influences, protection tubes made of pure ceramics, noble metals, high-temperature alloys or sapphire are used, depending on the application.
Connection wires
Connection cables for thermocouples and resistance thermometers are assembled by hand. Copper wires made of a low-stress copper alloy are used, which was specially produced for our thermometers. The insulation sheath is a strong textile sheath made of heat-treated fibreglass protection hose which is resistant to high temperatures. This protects the individual wires from mechanical stress, high temperatures and organic solvents.
High quality carrying case
All eXacal thermometers are delivered in a case, but can alternatively be ordered with a high-quality wooden carrying case. Due to the robust wooden case with the customised foam insert, the fragil thermometers are well protected during transport and storage.
