Linear Sensors | CAL3K Features

The linearity of the temperature sensing stems from the platinum resistance sensors. They are not very linear, but are highly predictable. The temperature linearity is achieved with embedded firmware inside the vessel.

This feature applies to the following CAL3K Systems : CAL3K-AP , CAL3K-A , CAL3K-U , CAL3K-F


The temperature accuracy comes from the platinum resistance sensors, which are very stable over time. The absolute temperature accuracy is 0.01°C (maybe it is 0.001°C), however the repeatability is 0.00001°C (10ppm).

The temperature range is very linear and wide. The low end includes +1°C, and the high end 72°C, although we only recommend a maximum operating temperature of 50°C, because it is reasonably comfortable to touch.

With the dry method, the water and container are replaced by a highly temperature conductive aluminium jacket which is shrunk over the stainless steel body of the vessel at a very high pressure and forms an integral part of the Vessel.
