A temperature measuring and monitoring arrangement, in particular for leak detection on pipelines. A number of temperature sensors (30) are arranged in a distributed array along the item to be monitored and are connected to one or more computers (15, 19) by way of communication units (10) and at least one serial connecting line (11). The temperature sensors (30) have a measuring member and a reference member which are included as a frequency-determining member in a measuring oscillator and a reference oscillator respectively. The temperature can be corrected and in particular drifts can be substantially eliminated by suitable mathematical treatment of the frequency values. Anomalies in respect of temperature distribution can be interpreted as a leak in a pipeline.
