- Description
- REQUEST FOR QUOTATION SB1341-07-RQ-0324 AMENDMENT #0001 The above referenced request for quotation is hereby amended to respond to technical questions, and change the due date for quotes. (1) The following responses are provided to technical questions submitted: QUESTION: Is it required to have IEEE 488 access to the controller system, or to the temperature measurement devices? ANSWER: b. Embedded controller computer: i. 512 MB RAM or better memory ii. 2.0 GHz or better processor speed iii. 10, 100, 1000 Base TX (Gigabit) Ethernet port iv. 4 or more USB 2.0 ports v. 40 GByte or better hard drive vi. IEEE-488 and RS-232 interface cards installed Embedded controller computer configured with IEEE-488 and RS-232 to interface with any auxiliary equipment necessary for furnace operation. QUESTION: Is it required to have a single controller with 24 temperature inputs and 24 control outputs? ANSWER: c. Instruments i. Voltmeter with following specifications: Resolution: 10 nV on 100 mV scale CMRR greater than 140 dB NMRR greater than 100 dB Noise less than 1.5 microvolt peak to peak, for 60th sec. integration. Greater than 10 Gohm input resistance DC volts accuracy better than (20 ppm reading plus 8 ppm of range) at temperature within 1 degree Celsius of self-calibration, for 2 years. ii. Digital-to-analog instrument with the following specifications: 16 or more channels Plus or minus 1 mV accuracy on plus or minus 10 V range 16 or more bit resolution iii. Scanner with the following specifications: 24 or more channels, each consisting of one pair of leads Maximum 2 microvolt differential thermal emf, for each channel iv. Power supply, with adjustable outputs of 0 to plus 6V, 0 to plus 20V, and 0 to minus 20V. Single Embedded controller computer capable of interfacing with scanner to measure thermocouple voltages from multiple furnaces with control voltages output to DC power supplies. QUESTION: Does a single temperature measurement correspond to a single control output? ANSWER Yes. (2) The due date for quotations is hereby changed to read as follows: FROM: Friday, July 27, 2007, at 3:30 PM EST, TO: Tuesday, July 24, 2007, at 3:30 PM EST. NOTE: THIS NOTICE WAS NOT POSTED TO FEDBIZOPPS ON THE DATE INDICATED IN THE NOTICE ITSELF (19-JUL-2007); HOWEVER, IT DID APPEAR IN THE FEDBIZOPPS FTP FEED ON THIS DATE.
