Honeywell S7965 UV Sensor Module

Honeywell S7965 UV Sensor Module — UV Flame Detection for Industrial and Commercial Burners in Saudi Arabia

The Honeywell S7965 is a UV sensor module providing flame detection input to Honeywell flame safeguard relays. As an accessory to the C7962 UV flame scanner or a standalone UV detector, the S7965 delivers reliable ultraviolet flame detection for gas and oil burner applications across Saudi Arabian industrial facilities.

The S7965's compact design allows direct mounting on the burner or installation in a control cabinet — flexible installation options for Saudi Arabia's diverse burner configurations from small commercial units to large industrial process heaters.

Key Features

UV Detection: Detects UV radiation from flame — compatible with both gas and oil flames without the soot-related reliability issues of flame rod detection.

Self-Checking: Performs continuous self-test — fails safe within 2 seconds of UV tube failure or signal loss.

Compact Housing: Small form factor for flexible mounting — can be mounted directly on the burner or remotely in the control cabinet with appropriate fiber optic cable.

Compatible with R7847 Relay: Designed to work with the Honeywell R7847B flame safeguard relay — provides complete flame detection circuit for burner management systems.

Applications in Saudi Arabia

Aramco Process Heater: S7965 provides UV flame detection for gas-fired process heaters — replaces flame rods for more reliable flame monitoring on high-wattage gas burners.

SEC Gas Turbine Starting Pilot: S7965 monitors ignition pilot flame in gas turbine starting sequences — critical for safe turbine start-up in Saudi power generation facilities.
