HTS IFM – S55xBE(PF) Series Viewing Heads

Overview

The Honeywell S55xBE(PF) Series are single-channel UV, IR, and UV+IR combination viewing heads designed for industrial flame scanning applications. They must be used in conjunction with P522, P531, or P532 signal processors to form a complete flame monitoring system. Multiple sensor configurations provide flexibility across a wide range of fuel types and burner arrangements.

All S55xBE(PF) models feature electronic self-check (no mechanical shutter), an embedded temperature sensor, and a two-digit numeric display on the rear of the viewing head for real-time UV and IR flame count readout. Models are available in Turck connector or pipe fitting (PF) configurations and are mountable in any orientation.

Features & Benefits

• Multiple sensor options (UV+IR, IR only, UV only) provide application flexibility across varied fuel and burner types
• Electronic self-check on all models — no mechanical shutter required, reducing maintenance and failure points
• Two-digit numeric display on the rear of the viewing head shows live UV (green) and IR (red) flame counts without connecting to the signal processor
• Embedded temperature sensor allows internal temperature readings directly from the connected signal processor
• Adjustable UV gain (0–99) and IR gain (0–699) configurable remotely from the signal processor front panel
• Selectable IR flicker frequency filters (16 Hz, 24 Hz, 33 Hz, 52 Hz, 75 Hz, 100 Hz, 155 Hz, 215 Hz) optimize detection across fuel types
• Settings stored in EEPROM in the connected signal processor — retained through power loss and restored upon power-up
• Mountable in any orientation with 1 in. NPT female process connection and 1/2 in. NPT female purge air port
• Compatible with Honeywell FASA fiber optic extension products for high-temperature remote mounting applications
• SIL 3 “Fit for Use” rated in low demand safety applications
