show the cooling section 16 and unloading conveyor 20 respectively in order to a have a better understanding of the process flow b for sending appropriate commands to the network nodes and c to avoid unnecessary esds it is required to collect all of the important information and parameters of the system in plc cabinet 32 and pc station 34 the present invention concentrates on one of the most important parameters of the htbs which is the glass temperature the corresponding monitoring technique must be selected according to the specific process characteristics the present invention uses thermography as the condition monitoring techniques to find an appropriate method for the temperature control other techniques like vibration monitoring tribology visual inspection process parameters and ultrasonic can not be easily used for the temperature monitoring and control of the glass generally in htbs furnace instrument for measuring the glass temperature is thermocouple 40 and 42 to have a high reliable output reading it is necessary that thermocouple 40 or 42 touches the media continuously here the molten glass 48 can not be touched by thermocouple 40 or 42 so it is situated somewhere near the molten glass 48 and measures the temperature of the points nearby the glass the molten glass 48 causes the thermocouples 40 42 output reading to be less reliable and more uncertain said thermocouples have delay in response to glass temperature changes because it takes time for the air temperature near the glass to follow the glass temperature said thermocouples also ignore the rapid oscillations of the glass temperature these constraints cause to use of a no tactile sensor the present invention.
