Relying upon a technical write-up by the appellants Manager, Control and Instrumentation and the manual for C-E Flame Sensing System Series 510" of Combustion Engineering Inc. the suppliers of the goods in the instant case, the learned Consultant has urged as follows:- The CE Series 510 Flame Scanner is a wide angle optical flame sensing device specifically designed for Hydrocarbon Fuels such as Coal, Oil and Gas or combinations thereof. Sensitive only to a wide band UV Radiations peculiar to hydrocarbon combustion, the Flame Scanner will not respond to radiation from hot refractory or slag. The complete mechanical assembly is composed of a stationary part and a removable part called respectively the Flame Scanner Guide Pipe Assembly and the Flame Scanner Head Assembly ................................................................... . ................................................................................ .....

Three light emitting diodes (L.E.D. s) are provided on the receiver module. There are identified as Flame , 1/2 Time and 1/4 Time . The Flame L.E.D. is lit whenever this module has a flame output. It indicates that flame pulses are being received at a rate greater than one every 2 seconds. The 1/2 Time L.E.D., when lit, indicates that 1 second has expired since receiving the last flame pulse. The 1/4 Time L.E.D., when lit, (at which time the 1/2 Time will turn off) indicates that 1.5 seconds has expired since receiving the last flame pulse. With a time interval between flame pulses of greater than 2 seconds, the 1/2 Time L.E.D. will turn on 1 second after a pulse. The 1/2 Time L.E.D. remain on for .5 seconds at which time the 1/4 Time L.E. D. will turn on. The 1/4 Time L. E. D. will remain on for .5 seconds, and when it turns off the Flame L.E.D. will also turn off. Two pulses with a time interval between pulses of less than 2 seconds are required to restore the Flame indication. 3.1 The learned Consultant further urges that electric sound or visual signaling apparatus refer .....

Regarding classification of an item lens in appeal No. C/2031/1988 the learned Consultant urges that they concede stand of the department that it is classifiable under CTA heading 90.01 and they do not press for their claim for its assessment under CTA Heading 90.02 read with Heading 90.28(4). 6. Opposing the contention of the appellants the learned SDR Shri ASR Nair reiterates the findings of the lower appellate authority. He urges that apparatus under consideration merely senses the flame, i.e. detects the flame. It does not measure or check intensity of the flame. He further points out that Flame Detector specifically mentioned at page 1442 of the Explanatory Notes as already mentioned above falls under CTA Heading 85.17. He submits that although there is no photo-electric cell in the apparatus under consideration, however the function is the same as that of a Flame Detector referred to at page 1442 of the Explanatory Notes. He further submits that a measuring instrument has to specifically measure the value of a desired parameter. No such thing is done in the in .....

It further mentions that this heading includes, inter alia: (A) Electric bells, buzzers, door chimes, etc. (B) Electric sound signalling apparatus, horns, sirens, etc. (C) Other electrical signaling apparatus (winking or intermittent lights, etc.) for aircraft, ships, trains or other vehicles. (D) Indicator panels and the like, for calling personnel, indicating where a certain person or service is required, etc. (E) Burglar alarms. (F) Fire alarms. 9. Explanatory Notes also provide that alarm consists of two parts, a detecting part and a signalling part. In the section relating to fire alarm, flame detector has been specifically included but these flame detectors, it is apparent, do not perform the job of measuring the intensity of the flame. The flame detector included in Heading CTA 85.17 operates the alarm through relay when the flame lights or goes out. This Explanatory Note pertaining to flame detector at page 1442 a .....
