When measuring temperature using a Thermocouple cold junction compensation is critical. It provides a reference to the thermocouple measurement. The MCP9804 provides the cold junction compensation at &plusmn;1&deg;C accuracy. If the Thermocouple is compensated using the compensation equation provided by National Institute of Standards and Technology (NIST ITS-90), then temperature can be measured with &plusmn;1&deg;C accuracy over the entire measurement range.</p> <p>The MCP3421 and the MCP9804 serial output lines are connected to a PICMicro Microcontroller.

and an 18-bit ADC, MCP3421. This solution eliminates the need for the traditional analog instrumentation system calibration or gain and offset trimming techniques. In addition, the Thermocouple linearization techniques can be implemented in firmware or software.</p> <p>The Thermocouple Reference Design allows user to evaluate Microchip&rsquo;s solution to accurately measure the temperature. When measuring temperature using a Thermocouple cold junction compensation is critical. It provides a reference to the thermocouple measurement. The MCP9804 provides the cold junction compensation at &plusmn;1&deg;C accuracy. If the Thermocouple is compensated using the compensation equation provided by National Institute of Standards and Technology (NIST ITS-90), then temperature can be measured with &plusmn;1&deg;C accuracy over the entire measurement range.</p> <p>The MCP3421 and the MCP9804 serial output lines are connected to a PICMicro Microcontroller. This controller communicates with a PC via the USB interface and commands the ADC to convert voltage. The serial data is then displayed on the PC using the Thermal Management software in stripchart format.</p> <p></p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul id="ctl00_ctl00_PageContent_SubPageContent_dtFeaturesText" class="prepend-top"> <li>Thermocouple Reference Design</li> <li>Supports K-type Thermocouple</li> <li>USB interface to PC</li> <li>Graphical User Interface for temperature data-log</li> <li>Thermal Management GUI</li> <li>MCP9804 Temperature sensor with &plusmn;0.25&deg;C (typical) accuracy from -40&deg;C to +125&deg;C</li> <li>18-Bit ADC MCP3421</li> <li>USB interface to PC</li> <li>PIC18F2550 PIC Microcontroller</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Thermocouple Reference Design, 102-00114</li> <li>K-type Thermocouple</li> <li>Important Information Sheet</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Data Sheet</h4> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/22203C.pdf" target="_blank">MCP9804 Data Sheet (pdf)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/22003e.pdf" target="_blank">MCP3421 18-Bit ADC with I2C Interface and Onboard Reference (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Solution Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/50001894D.pdf" target="_blank">Quick Guide to Microchip Development Tools (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">User Manual/Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/51889a.pdf" target="_blank">Thermocouple Reference Design User Guide (pdf)</a> </div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Applications Library</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/102-00114b.zip" target="_blank">Thermocouple Reference Design (TMPSNSRD-TCPL1) Firmware (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Design Package</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/ThermalManagementUtility.zip" target="_blank">Thermal Management Utility (v1.5.2) (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/00114R2_Gerbers.zip" target="_blank">TMPSNSRD-TCPL1 Gerbers (zip)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: sensing, microchip, MCP9804, temperature, pic18f2550, analog_demo_boards, mcp3421</div>
