Honeywell C7035A1023/U UV flame detector

Honeywell C7035A1023/U photoconductive cells are used to determine the presence of ultraviolet radiation emitted by a flame. Flame detectors are used with Honeywell flame monitoring systems to detect the presence of flames in gas, oil and combined burners.

Features

• The Resideo C7035A1023/B photo cells are used together with the R7249A, R7290A, R7749B and R7849A, B amplifiers and the corresponding Honeywell control devices.

• The flame detector C7035A1023 has a built-in cuff with an internal thread of 1-11-1/2 NPSM for installation on a one-inch inspection tube.

• The housing of the Honeywell C7035 A 1023 flame detector meets the requirements of Underwriters Laboratories Inc. for protection against moisture penetration and the NEMA standard for cabinets of type 4 and 4X.

• When properly installed, the C7035A 1023 can be used at pressures up to 5 psi.

• The UV reading tube C7035A 1023/U is replaced in the field.

• Two flame detectors C7035 A 1023/B can be connected in parallel in cases where flame reading is difficult.

Specifications

Flame detection: End of flame.

Ambient temperature range: -18°C to +121°C or -40°C to +121°C, depending on the model.

Maximum allowable pressure: 5 psi (34.5 kPa).

Installation: Cuff with 1-11-1/2 NPSM internal thread for installation on a one-inch inspection tube. (DIN-certified model C7035A1064 has thread 1-11 BSP.P1)

Electrical connections: Two wires 6 ft [1.83 m], color-coded, NEC Class 1, rated up to 204°C. One model comes with 12 ft [3.66m] long wires). There is a 1/2-14 NPSM thread at the back of the detector for connecting the wire.

Basic requirements for the installation of an ultraviolet flame detector

The flame creates ultraviolet radiation that is invisible to the human eye, but can be detected by a special tube reading ultraviolet radiation. There are two requirements that must be met when installing an ultraviolet sensor:

• The detector must be in the direct line of sight of the flame.

• The detector must not be exposed to other ultraviolet radiation, primarily from ignition sparks.

• The detector must necessarily "see" the flame and therefore it must be located as close to the flame as physical conditions and temperature restrictions allow.
