Description
The Honeywell UV detector minipeeper C7027A1049/U is an industrial flame sensor that detects ultraviolet radiation emitted by flames. It features a 1/2-14 NPSM internal thread for installation on inspection tubes and is compatible with Honeywell R7249A, R7290A, R7749B, R7849A, R7849B, and R7851B amplifiers or control devices. The detector operates at pressures up to 5 psi (34.5 kPa) and is available with wire lengths of 6 feet (1.83 m) or 24 feet (7.32 m). Spare parts include flange seal 129685.
Further details
| Application | Flame detection in gas, oil and combined burners |
|---|---|
| Electrical connection | Two color-coded wires, NEC Class 1 |
| Parallel Connection | Two detectors can be connected in parallel |
| UV reading tube installation | Installation on inspection tubes of various diameters |
Choosing and fitting
Parts of this type are selected by matching the detector's connection thread and electrical specifications to the burner's mounting and amplifier requirements. Installation involves securing the detector to an inspection tube using the internal thread and connecting the color-coded wires to the compatible amplifier. Ensure the pressure rating and temperature range of the detector suit the application.
Signs of failure
When UV detectors of this kind fail, the burner may fail to ignite or shut down unexpectedly due to loss of flame signal. Symptoms include intermittent flame detection or a complete lack of response to flame presence. Check the detector's lens for dirt or damage, verify wiring connections, and test the amplifier compatibility.
