SYSTEM APPLICATION
The Det-Tronics model R7404 Controller and C7050
Detector provide fast, reliable flame detection in a wide
variety of applications. The microprocessor based
controller simultaneously monitors up to 16 C7050
ultraviolet (UV) detectors in up to 8 different zones. The
system uses the Automatic Optical Integrity (o
i
) feature,
which provides a continuous check of detector optical
surfaces, detector sensitivity, and electronic circuitry of
the detector/controller system. Also included is automatic
fault identification, which monitors the system for proper
operation, and provides a digital display of system status
using a numerical code. Other features include individual
zone identification and “voting” capability, as well as
manual o
i
testing.
The C7050 Detector responds instantly to the ultraviolet
radiation that is emitted by a flame. It is designed for use
in hazardous locations and is particularly suitable for use
in outdoor applications because it is not affected by wind
or rain, and is insensitive to solar radiation. In addition,
the detector does not respond to normal artificial light.
Typical applications for Det-Tronics UV detection systems
are:
— Wherever highly combustible materials are involved
— Where there is a need for instantaneous response to
flame
— Wherever unsupervised areas require automated fire
protection
— Where there is a large capital investment to be
protected.
Examples of actual installations using the Det-Tronics UV
detector in automated fire protection systems include:
Petroleum Products
— Gasoline transport loading terminals
— Offshore drilling and production platforms
— Pipeline pumping stations
— Tank farms
— Refineries
— Marine engine rooms
— Jet engine test cells
Gaseous Fuels
— Butane and propane loading and storage
— Pipeline compressor stations
— Gas gathering facilities
— Pipelines in highly populated areas
— LNG loading, transfer and storage facilities
— Hydrogen and ammonia production and refinery
reformers
— Gas turbines
