Sažetak
Within the work package one of the ongoing EMPIR project „Developing Traceable Measurement Capabilities for Monitoring Thermocouple Performance” (MetForTC), the novel concept of dual-type temperature probes was developed. By using dual-type temperature probes, users would be able to continuously monitor the thermocouple drift in-situ, including environments with varying temperatures. The concept is developed mainly for use in industry, where the drift of thermocouples can lead to various problems, such as increased energy consumption, loss of raw material, or decrease in quality of products. To mitigate the problems related to thermocouple drift, industrial users tend to replace thermocouples regularly, in some cases even after only a few days of usage. Using this approach, thermocouples can be occasionally replaced too early as well as too late. Dual-type temperature probe consists of a monitored thermocouple sensor and an additional temperature sensor, accommodated within the same protective sheath. The use of an additional (reference) sensor, which experiences a lower drift than the monitored thermocouple (e.g. higher grade thermocouple wires, platinum resistance sensors, or fiber-optic sensors), enables monitoring of thermocouple drift by continuous comparison of the differences in their temperature readings. While the drift of the monitored thermocouple can be tracked continuously, the concept also enables occasional tracking of drift of the reference sensor.
