InSight II 95DSS3 Flame Scanner

The Fireye® InSight® II Type 95DSS3 flame scanners are microprocessor based flame scanners utilizing solid state infrared (IR) and ultraviolet (UV) sensors.

The Fireye InSight II flame scanners incorporate two internal flame relays with adjustable ON/OFF thresholds and two 4-20 mA analog outputs, thereby eliminating the need for a remote flame amplifier.

The Fireye InSight II scanners are powered by 24 vdc and have electronic self-checking. Model 95DSS3-1 has one 8-pin and one 12-pin electrical cable quick disconnect. Models 95DSS3-1CEX and -1WICEX have internal terminal blocks for cable connection. The scanners have either an attached Keypad & VFD display, or an infrared transmitter for a remote handheld keypad/display.

The 95DSS3-1CEXSS scanner utilizes advanced techniques for discrimination and integrate the flame detection, amplification, safety determination and flame switch functions into a single detection head. No separate amplifier or flame switch module is therefore required to interface with the main burner management system. 95DSS3-1CEXSS is a dual cell scanner utilizing UV and IR detectors and a stainless steel housing which includes CE and ATEX ExdIIC approvals when suitable connectors and fittings are used. Model 95DSS3-1CEXSS includes the alpha-numeric VFD Display and Keypad. Standard features include two independently adjustable Flame Relays that can be selected to operate from the UV sensor, the IR sensor, or both sensors, 21 choices of modulation frequency, adjustable sensor gain, adjustable flame relay ON/OFF thresholds, two 4-20 mA analog signal strength outputs (one for FR1 and one for FR2), Fault Relay, four selectable programmable files (e.g. for different fuels or firing rates), and Auto Config capability with manual override. Remote communication capability is available via optional “Fireye Explorer” PC software
