Product: Digital Profile

The DPD detector is a self contained detector with automatic UV or IR tuning capability. Input power and output flame signals are made through a rugged military style connector. In addition to the tuning from the key pad on the rear of the detector, tuning can be accomplished remotely through a computer connection.

Product Overview

DIGITAL PROFILE DETECTOR ™

THE PATENTED DIGITAL PROFILE DETECTOR (DPD) USES A MICROPROCESSOR TO continuously monitor the frequency and amplitude characteristics of a burner flame. Every flame has a unique profile – a digital fingerprint. The Digital Profile Detector constantly compares the real time flame image to the learned profile stored in its memory. The detector’s microprocessor uses sophisticated algorithms to precisely determine the flame’s on/off condition, allowing for reliable discrimination in a multi-burner environment.

Depending on customer needs, both the Super-Blue Digital Profile Detector (UV) and the Classic Digital Profile Detector (IR) are available. The Super-Blue features a super-blue silicon cell that is sensitive to radiation prevalent in gas flames and/or oil flames. The Classic incorporates a lead sulfide cell for infrared detection and is best suited for coal and/or oil flames. The automatic signal amplification circuitry and the use of multiple storage files allow each Digital Profile Detector to adapt to each application.

Solutions & Applications

SOPHISTICATED SMARTDISPLAY ™ SIMPLIFIED MAINTENANCE
The scrolling LED display provides quick set-up, precise aiming, and instant flame signal readout. In the event of failure, downloading and uploading flame characteristics to a replacement detector head is possible.
SIMPLIFIED PROGRAMMING AND OPERATIONS SAFE OPERATION
With the push button keypad, the detector can be programmed to learn flame data in just minutes. 24 VDC operation.
FIBER OPTIC CONNECTIONS USER FRIENDLY
For space constricted applications, fiber optics can work through the tightest burner configurations. Program and view multiple detector’s status from a remote PC.
OPTIFLAME COMPATIBILITY
The OptiFlame burner balancing software uses the detector’s signal to help fine tune the performance of a burner.
