Product Overview

Features & Bene ts

 e Forney D85 series is a microprocessor based  ame detector

utilizing a solid state  ame detection sensor.  e D85 incorporates an

internal  ame relay with automatically set ON/OFF thresholds and

advanced programming features for  ne tuning.

Forney’s D85 detects the modulation of the target  ame’s amplitude

( ame “ icker”) over a wide frequency. During the detector setup the

amplitudes of the target  ame are automatically stored in the  ame

detector along with optimum ON/OFF criteria.  e appropriate

sensor gain is also automatically selected and stored. Forney D85

detectors incorporate full self-diagnostic and electronic self-checking.

Forney D85  ame detectors are powered by 24Vdc with standard

analog 4-20mA  ame signal strength output. Electrical connection

is via an 8-pin electrical quick-disconnect (QD)  tting for standard

models. CEX models utilize internal terminal blocks.

Forney D85  ame detectors are available in multiple models based on

spectral range (UV or IR), hazardous area classi cations and agency

approvals.

• Rapid installation and con guration

with quick disconnects and fully

automated tuning.

• Advanced, programmable settings for

more demanding applications

• Expanded diagnostic analysis for

superior  ame characterization and

troubleshooting.

• Multiple UV and IR  ame detection

options support a wide range of

combustion processes including:

industrial burners, duct burners,

re nery applications, low NOx

burners, waste fuel units and

incinerators.

• Integrated sensor and electronics

eliminates need for external ampli ers.

• Standard NEMA 4X, IP66 housing

for Class I, Div 2 environments

• Optional CEX models for ATEX Ex

II 2 G/D environments
