Retrofit Gas Kiln Atmospheric Monitoring System

摘要

An atmospheric monitoring system designed for a low cost retrofit installation into a non commercial potter's gas fired kiln. The system uses a low cost, replaceable, unshielded oxygen sensor incorporated into a modified firebrick for simple installation into a kiln. There is also a high temperature thermocouple inserted through an orifice through the kiln wall such that it senses the temperature adjacent the wares. The system has three embodiments with successive levels of complexity that build onto each other. The simplest system has a base unit for localized visual display of the kiln's atmospheric parameters. The higher levels run a software application on their smart phones that allows for more comprehensive data reporting but more importantly, provide for redundant alarm notification through the LAN and the 4G cell phone network.
