- The purpose of this modification is to deem commercial, change ranges for CLIN 0001 and add CLIN 0002 of the subject solicitation FA8104-06-R-0598. FIRST: This item has been deemed a commercial item and FAR Part 12 will apply. SECOND: Change ranges for CLIN 0001 of the subject solicitation FROM: Quantity range A from 10 EA to 20 EA Quantity range B from 21 EA to 32 EA TO: Quantity range A from 18 EA to 36 EA Quantity range B from 37 EA to 56 EA THIRD: Add a BEQ of 37 to CLIN 0001 of the subject solicitation. FOURTH: Line item 0002 for FMS has been added as referenced below. FIFTH: All other terms and conditions remain unchanged and in full force and effect. PR Number(s): 2915013432931PR, FA810406R0598, FD20300780458 Item: 0002 NSN: 2915013432931PRPR SENSOR,TEMPERATURE, P/N: 1534M60P04, Description: Temperature is sensed by a helium-filled sensing coil acting upon sensing bellows attached to a metering valve. A second bellows is reference bellows. Pressurized helium gas in sensing coil reacts to temperature changes. When temperature increases, gas pressure increases. When temperature decreases, gas pressure decreases. Control servo pressure (PC) is supplied through a fixed orifice in main engine control. Pressure between fixed orifice and metering valve is P6 Pressure. Pressure (P6) is regulated to that required to overcome force of helium acting on sensing bellows, plus force of preload springs, plus force of bypass pressure (PD) acting on reference bellows. This interaction of forces regulats P6 at a constant value above PD at a constant value above PD at a given temperature. An increases in temperature expands helium gas in sensing coil and sensing bellows. As sensing bellows expands, opening at metering valve is decreased. A smaller amount of P6 is than blec to PD, thus increasing P6 pressure. A temperature decrease in helium-filled sensing coil causes gas to contract. As gas contracts, metering valve opens farther, bleeding more P6 pressure to PD, and P6 pressure decreases. The reference bellows allows for variations in PD and is used to maintain absolute pressure reference. FUNCTION: The sensor is a temperature sensor and transducer unit for main engine control. It responds to changes in fan discharge temperature and regulates pressure as a function of discharge temperature. DIMENSIONS: 'Sensor body/length 3.000inches, width 4.390 inches, height 2.400 inches. Temperature coil dimensions: length 7.188 inches, width 2.750 inches, height 2.750 inches, weight (dry) 2.82 lbs, signal pressures 24.1-182.4 PSI above main fuel pump boost pressure and proportional to temperature, filter screen size 70 microns (nominal), pressure line connection0.562-18 UNF-3A thread, temperature range -65F to 480F. MATERIAL: consists of aluminum exterior surfaces anodized per MIL-L-8625 class I Type II. Total Line Item Qty: 5.0000 Destn: DTK002,, ., - . Delivery: 31DEC2007, 5.00 Electronic procedure will be used for this solicitation. Note 26 DOES NOT APPLY
