The present invention provides a highly sensitive, intelligent, reliable, and effective process and system for detecting fire, which may be used in any industrial or other environment. The process and system for flame detection in accordance with the present invention features wide infrared spectrum sensitivity, which facilitates increased sensitivity to any sign of a flame or fire. The process and system of the present invention utilizes digital processing and analysis of data, calibration of operation parameters from temperture data, an intelligent controller (microprocessor) for discriminating against false alarms, and an elaborate multi-stage alarm system, selectively triggered by the controller.

Process and system for flame detection

A system and method for detecting and controlling ungrounded parts during the electrostatic coating process in order to improve production flow, provide an overall cost saving by efficient use of the coating material and prevention of accidental fires and false shutdown during production. The system of the present invention comprises a detection system for detecting any ungrounded parts prior to entering a coating environment, such as a painting booth. The detection system in accordance with one embodiment, comprises an array of detectors, specifically, an ultraviolet sensor, a radio-frequency wave sensor, an acoustic sensor and a light sensor, which upon sensing specific characteristics generate representative signal waveforms. These waveforms are than compared with stored waveforms relating to profiles of sparking or corona discharge characteristics. Correlation circuits may correlate data obtained by two or more sensors in order to ensure that the spark or corona discharge is caused by an ungrounded part. In accordance with an alternative embodiment, the detection system comprises a measuring device, such as a sensitive electric field meter, for measuring the electrical potential field between each part to be coated and ground.

The present invention relates to a flame detector and protective cover with wide spectrum characteristics. The novel flame detector has wide spectrum sensitivity, which facilitates increased sensitivity to any sign of a flame or fire. The protective cover has wide spectrum transmittance characteristics. The protective cover facilitates reduced cleaning requirements and less disruption of the automated process for cleaning purposes. The wide spectrum transmittance characteristics of the protective cover enable it to be used with any flame detector utilizing non-ultraviolet sensing techniques.
