Monitoring of the Thermal-Moisture Regime at St. Jacob´s Church in Levoča UNESCO Site, Eastern Slovakia

The paper deals with the monitoring of thermal-moisture regime, as one of the deterioration factors within the rock material at UNESCO historic site, particularly in the supporting pillars of St. Jacobs’s church in Levoca, Eastern Slovakia. The moisture sensor consists of a small cylinder having the diameter and length of 20 mm in which a small ball of 2 mm diameter is placed that delivers the heat in step-wise regime and simultaneously measures temperature. Two sensors have been positioned in South-North orientation and embedded in the church supporting pillars. During monitoring we have identified diffusion of moisture associated with cycle day/night and cycle wetting/drying caused by meteorological precipitation.
