Spark/Arc Detection System from Scanning Devices, Inc.
Simple But Effective - Our arc detection system consists of one or two photoelectric sensors mounted within equipment to view the energy
delivery region. These are wired to a plug-in photoelectric amplifier consisting of a power source for the photo sensors, adjustable gain amplifier
stage, and output switch. The amplifier's output changes when infrared energy impinges on the photo sensors. The output is wired to industrial oven
controls to take appropriate action.
Installation Flexibility - Separate sensor and amplifier allow separation of the components by cable and installation of the amplifier away from the
energy delivery area in a convenient location with other control equipment.
Numerous Models and Setup Options - Variations in input power, output switch type, fail-safe configuration. Amplifiers are available powered by
120 VAC or 24 VDC. Outputs include mechanical relays and optically coupled isolators suitable for PLC connection as well as high-speed solid- nd
state switches. Amplifiers can be setup to energize output on spark or no spark.
