Prediction of condensation formation on the drums of a tape recorder device etc. by measurement of drum, temperature, surrounding air temperature and humidity and predicting a condensation temperature from the data

摘要

Device comprises a device for determining the temperature of object, such as a magnetic tape forwarding drum, in an electronic apparatus, a device for determining temperature of the surrounding area, which in conjunction with a measurement of air moisture content is to predict condensation formation if the temperature of the magnetic tape drum is not above condensation point. Independent claims are made for a procedure for determining if condensation will be formed on an object in an electronic apparatus, for a device and a for a procedure for determining surrounding environment temperature and a display or reproduction system for a helical temperature scan system for a tape drum.
