The system can be adjusted to various sensitivity levelsby programming the controller to respond at a pre-deter-mined detector tube count rate. This

Since moisture can be detrimental to electronic devices,it is important that moisture not be allowed to come incontact with the electrical connections

SYSTEM APPLICATIONThe Det-Tronics model R7404 Controller and C7050Detector provide fast, reliable flame detection in a widevariety of applications. T

Solid Materials—Munitions production such as illuminating flare materi-al, TNT, and other propellants—Powder coating boothsOther Processes—Paint Spray

The output of the detector consists of a series of voltagepulses or “counts.” The frequency of these pulses isdirectly proportional to the intensity

resistance is 16.14 ohm/1000 ft. or 53.0 ohm/km.) TheR7404 Controller will accommodate up to 16 detectors.The detectors can be located up to 2000 fee

DETECTOR SENSITIVITYThe UV flame detector responds to radiation over wave-lengths of 185 to 245 nanometers (1850 to 2450angstroms). Figure 6 illustra
