Abstract
A detector for indicating the presence of a refrigerant gas generally includes a source of flammable fluid, a burner having associated therewith a reaction element and a detector circuit. The burner is adapted to combust the flammable fluid to produce a flame about the reaction element while the detector circuit, which includes an optoelectronic color sensor in view of the flame, is adapted to signal the presence within the combusted fluid of a refrigerant gas. The indicator may be visual or audible. The burner may include a shield, which may serve to sink heat away from the sensor and/or to shield the flame from ambient breeze.
