Multipoint thermocouple probes are frequently used in oil and gas industry and chemical applications to detect temperature profiles. Because of the critical process conditions inside the vessels, the sheaths of such probes might be affected by crack phenomena. Due to that the process fluid might penetrate through the sheath, causing electrical insulation drops, measurement drift and in the worst case overall short circuits. A new thermometer design aims to be a more robust solution thanks to its double sealing layers, double insulation layers and completely independent sensors.
