Abstract

A nonintrusive temperature measuring apparatus for measuring the fluid temperature in at least partially thermally insulated tubes of installations in the processing industry, has the tube is completely sheathed by a thermal insulation layer at least at the measurement point, wherein a sensor electronics system with a temperature sensor is mounted onto the tube within the thermal insulation layer, a connecting electronics system is arranged outside the thermal insulation layer, and wherein the sensor electronics system and the connecting electronics system have one or more energy transmitters for wireless energy transmission for supplying the sensor electronics system and one or more temperature transmitters for wireless communication for transmitting the temperature measurement values from the sensor electronics system to the connecting electronics system.
