Title: Flammable gas detection element
Inventor: KISHI SHUICHIRO
IPC: G01N27/16
Filed: 1993-12-27
Abstract: PURPOSE:To obtain a flammable gas detection element with a stable performance for environmental conditions such as ambient temperature by layout out a heat-insulation plate between the gas detection element and a temperature- compensating element. CONSTITUTION:An element 1 for detecting gas is formed of coils 1a and 1b of two thin platinum wire integrally arranged, the outer periphery is covered with the carrier of a refractory powder such as alumina and magnesium, and a catalyst layer such as platinum and palladium is formed on the surface. In an element 2 for compensating temperature, a carrier is similarly deposited on two platinum wire coils 2a and 2b but no catalysis layer is provided. A heat-insulation plate 4 is laid out to prevent mutual interference between the elements 1 and 2. When a flammable gas contacts the element 1, contact combustion reaction is generated by catalyst operation and the temperature of the element 1 rises proportionately to the concentration of the flammable gas, thus increasing the resistance of the coils 1a and 1b and obtaining an output voltage proportional to the gas concentration as the unbalanced voltage of a bridge.
