- PR Number(s): FD20300980542Item: 0001 New Manufactured Material, IDIQ ContemplatedNSN: 2915013432931PRPR SENSOR,TEMPERATURE,P/N: 1534M60P04, Description: Temperature is sensed by a helium-filled sensing coilacting upon sensing bellows attached to a metering valve. A secondbellows is reference bellows. Pressurized helium gas in sensing coilreacts to temperature changes. When temperature increases, gas pressureincreases. When temperature decreases, gas pressure decreases.Control servo pressure (PC) is supplied through a fixed orifice in mainengine control. Pressure between fixed orifice and metering valve is P6Pressure. Pressure (P6) is regulated to that required to overcome forceof helium acting on sensing bellows, plus force of preload springs, plusforce of bypass pressure (PD) acting on reference bellows. Thisinteraction of forces regulats P6 at a constant value above PD at aconstant value above PD at a given temperature. An increases intemperature expands helium gas in sensing coil and sensing bellows. Assensing bellows expands, opening at metering valve is decreased. Asmaller amount of P6 is than blec to PD, thus increasing P6 pressure.A temperature decrease in helium-filled sensing coil causes gas tocontract. As gas contracts, metering valve opens farther, bleeding moreP6 pressure to PD, and P6 pressure decreases. The reference bellowsallows for variations in PD and is used to maintain absolute pressurereference. FUNCTION: The sensor is a temperature sensor and transducerunit for main engine control. It responds to changes in fan dischargetemperature and regulates pressure as a function of dischargetemperature. DIMENSIONS: 'Sensor body/length 3.000inches, width 4.390inches, height 2.400 inches. Temperature coil dimensions: length 7.188inches, 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 andproportional to temperature, filter screen size 70 microns (nominal),pressure line connection0.562-18 UNF-3A thread, temperature range -65Fto 480F.

The proposed contract action is forsupplies and services for which the Government intends to solicit andnegotiate with only one, or a limited number of sources under theauthority of FAR 6.302. Interested persons may identify their interestand capability to respond to the requirement or submit proposals. Thisnotice of intent is not a request for competitive proposals. However,all proposals received within forty five-days (thirty days if award isissued under an existing basic ordering agreement) after date ofpublication of this synopsis will be considered by the Government. ADetermination by the Government not to compete this proposed contractbased upon responses to this notice is solely within the discretion ofthe Government. Information received will normally be considered solelyfor the purpose of determining whether to conduct a competitiveprocurement.
