66 -- DIGITAL UNIVERSAL THERMOCOUPLE REFERENCE SYSTEM SOL F40650-97-R-0003 DUE 112596 POC Sue Tate, Contract Specialist, (615)454-7801 Arnold Engineering Development Center (AEDC) has a need for Digital Universal Thermocouple Reference System components to include 20-channel and 100-channel units. Each Digital Universal Thermocouple Reference System unit shall be a highly accurate temperature measuring system and shall consist of integral uniform temperature reference block, low-level multiplexer, dual-integration 16-bit analog-to-digital converter, measurement processor and Bitbus serial communications interface in an environmental enclosure. Temperature reference block shall be segmented into 5 channel modules each having a Pt100 platinum resistance sensor for precisely measuring the module's temperature. Each 20 or 100 channel unit shall sample and digitize the input channels at the rate of ten times per second per channel and shall output the data in a serial bit stream. Output bit stream shall be in IEEE-118 (Bitbus) format and shall consist of corrected thermocouple voltages and platinum sensor resistance. Units shall be designed for installation on the mounting structure of a turbojet engine being tested in an altitude test cell and shall withstand the environmental conditions encountered therein. Units shall provide an overall system accuracy of 0.2 degrees Celsius over an ambient temperature range of -20 to +60 degrees Celcius when operating in this environment. Units shall be self-calibrating using internal standards and shall maintain the above accuracy for a period of one year. Software shall be supplied for an IBM-compatible PC that willperform set-up, checkout and calibration of the Digital Universal Thermocouple Reference System. Bitbus interface and PC will be provided by the Government. Delivery of each shipment shall be FOB Destination no later than 90 calendar days after notice of award. The Government anticipates a total quantity of 23 each 20-channel units and 39 each 100-channel units. This is not a request for proposals. This procurement is being considered for a sole source five (5) year requirements contract to Kaye Instruments. Responses must be received not later than 15 days after date of publication of this announcement. Firms responding to this synopsis should do so in writing and indicate whether they are or are not a small business, or a small disadvantaged business. You may send requests by facsimile to (615)454-7330. See Note(s): 22. (0298)
