Abstract

Indicators placed in the concrete produce temp. measurement signals which are processed with the aid of special computer programs common for a large number of indicators. The signals are transmitted from the indicators to the computer after processing in a measurement data converter via at least one first radio transmitter/receiver to a second radio transmitter/receiver connected to the computer. - The signals are delivered into the computer via the radio transmitters/receivers through a command from the computer, and are stored together with time indications in the computer memory. The transmitters/receivers contain a number of different measurement frequencies and an indicator or indicator group is connected to each measurement frequency. - (Provisional basic advised week 9232)(Dwg.0/0)
