Flame Sensor Buying Guide
Selecting a flame-sensing component starts with the type of flame-detection system already in place. Compare the detection method, control or relay-module compatibility, connection style, mounting details, and service features before choosing a replacement or system component.

Maintain compatible flame-detection systems
Use flame amplifiers to process flame signals in compatible 7800 Series and R7140 relay-module applications. Choose sensor and detector components for replacement or service work on compatible heating equipment and burner-control setups.
Match the sensing method and interface
Start by identifying whether the system requires UV detection, a cadmium-sulfide detector, a mercury sensor, or a flame amplifier. Then verify relevant interfaces such as relay-module fit, threaded connection, plug or terminal configuration, element length, and lead length.
Support burner and heating-equipment operation
Products represented here are used with heating equipment, industrial and commercial single- or dual-fuel burners, flame safeguard controls, and compatible flame-monitoring systems. Some UV options address difficult flame-sighting applications or blast tube mounting where appropriate.
Consider service and monitoring features
Available features include flame-signal test jacks, dynamic self-checking, color-coded identification, an oscillating shutter, replaceable UV sensing components, alarm contacts, and safe-start or lockout functions on the electronic control.
Available on selected flame amplifiers for monitoring flame signal strength.
Represented mercury flame sensors use a 48-inch element.
The cadmium-sulfide detector includes 60-inch leads.
The compact UV flame sensor includes a 5 psi pressure seal when correctly installed.
Compare Flame Sensor Product Types
Use this overview to distinguish the component types represented in the category and the details to verify before selection.
| Product type | Primary role | Key comparison points |
|---|---|---|
| Flame amplifiers | Process flame signals in compatible 7800 Series and R7140 relay-module systems. | Confirm relay-module compatibility; compare keyed connection, test jacks, dynamic self-checking, color coding, and specified signal range. |
| Flame sensors and detectors | Provide flame-sensing components for compatible heating equipment and burner-control systems. | Compare sensing method, element or lead length, terminal or plug configuration, holder inclusion, mounting, and threaded connection. |
| Electronic flame detection control | Provides primary burner control and monitors rectification-type flame detection for specified single- or dual-fuel burners. | Compare flame-loss recycling, pilot lockout, safe-start check, SPDT alarm contacts, and mounting features. |
Plan the right fit before choosing
Choose a sensor, detector, amplifier, or control based on the existing system
The category includes several distinct component types. UV flame sensors and UV flame detectors support ultraviolet flame monitoring, while a cadmium-sulfide detector provides a cad cell eye with leads and holder. Mercury flame sensors are represented in bulb-style configurations with 48-inch elements. Flame amplifiers process flame signals in compatible relay-module systems, and the electronic flame detection control is a primary burner control for specified burner applications.
- For compatible 7800 Series and R7140 relay modules, compare flame amplifier options.
- For ultraviolet flame monitoring, compare UV sensor or detector mounting and control compatibility.
- For replacement sensing components, compare mercury-sensor connections or cadmium-sulfide lead length and assembly details.
Confirm the physical and electrical details required by the application
Connection and mounting details vary across the product types. The mercury sensor options include either two 1/4-inch spade terminals plus one pin terminal or a 3-pin plug. UV products include 1/2-inch NPT threaded-spud and sighting-pipe mounting details, as well as a 3/4-inch NPT connection on a shuttered detector. The cadmium-sulfide detector has 60-inch leads, and its holder is included.
- Match the required terminal or plug configuration for mercury-sensor replacement work.
- Compare 48-inch sensor elements and 60-inch detector leads where length matters.
- Verify threaded connection size, sighting-pipe mounting, and available installation orientation for UV products.
Select the features that support inspection and burner-control needs
Several amplifiers provide keyed edge connectors, flame-signal test jacks, dynamic self-checking, and color-coded labels. Specified amplifier options support monitoring within a 0.0 to 5.0 VDC signal range. The electronic flame detection control adds flame-loss recycling, pilot lockout, a safe-start check, SPDT alarm contacts, and captive mounting screws. A shuttered UV detector uses an oscillating shutter and works with compatible dynamic self-check amplifiers.
- Use flame-signal test jacks when voltage measurement is needed during service checks.
- Consider dynamic self-checking where detector and electronic-component testing is required.
- For a primary burner control, compare flame-loss response, pilot lockout, safe-start checking, and alarm-contact capability.
