FIREYE 85IRF1-1QD Integrated Flame Detector with Relay

1. Core Overview
FIREYE 85IRF1-1QD is a Phoenix 85IRF series flame detector produced by Fireye Corporation. This model belongs to the integrated design and is mainly used to detect the infrared radiation generated by industrial gas burners (compared to the UVF series for detecting ultraviolet radiation). Its biggest feature is the built-in flame relay that automatically sets the ON/OFF threshold value, without the need for additional remote amplifiers or independent flame switches.

2. Core features and technical parameters
Internal Relay: By automatically setting the on/off threshold through the built-in relay, the system design is simplified and response speed is improved.
Microprocessor technology: A solid-state flame detection sensor based on microprocessors, with self diagnostic and electronic self-test functions, capable of automatically selecting the appropriate sensor gain.
Working environment: typically suitable for industrial environments ranging from -40 ° C to+65 ° C, designed to comply with international standards such as AS 4625-2008&EN 298-2012
.
Communication and power supply: Requires 24V DC power supply, with 4-20mA signal output interface, usually connected through an 8-pin connector.
3. Application scenarios
This detector is widely used in industrial flame monitoring applications that require high safety and reliability, including but not limited to:

Flue afterburner: Ensure the stability and safety of the combustion process.
Industrial gas burner: used for equipment such as boilers and hot air stoves.
Refining equipment: detecting flame status in high-risk chemical environments.
Other high-temperature environments such as energy, petrochemicals, manufacturing, etc
.
4. Selection and installation precautions
Model difference: 85IRF1-1QD belongs to the infrared (IR) series, mainly targeting the infrared radiation generated by the combustion of hydrocarbons. If your fuel mainly consists of natural gas, coal gas, etc., it is recommended to prioritize the IRF series; If it is a mixed fuel of oil and gas or requires detection of ultraviolet radiation, it is recommended to choose the UVF series.
Installation requirements: During installation, ensure that the probe has an unobstructed field of view and keep the probe lens clean. It is recommended to use flexible or rigid conduit to connect cables to reduce electromagnetic interference
.
Summary: FIREYE 85IRF1-1QD is a highly integrated, self diagnostic, and easy-to-use infrared flame detector, particularly suitable for industrial combustion systems that require fast response and simplified wiring.
