Circuit provides cold junction compensation - 28-Nov-02 Issue of EDN
The accuracy of any circuit or system that uses a thermocouple to determine the
temperature of a process is limited by the accuracy of the method used to perform
cold-junction compensation. In a thermocouple measurement, two wires of dissimilar
metal join together at the "hot," or measurement, junction.... [Design Idea by Mark
Maddox, Analog Devices, Wilmington, MA, and John Wynne, Analog Devices, Limerick,

DPPs make nonvolatile microvolt DAC - 31-Oct-02 Issue of EDN The
availability of a seemingly limitless variety of monolithic DAC chips makes it easy to
implement most digital-to-analog-conversion applications with a single off-the-shelf
device. Sometimes, an unusual set of requirements necessitates a multichip approach,
however. One example of such a requirement is the need for nonvolatility of the DAC's
setting in power-up and -down cycles.... [Design Idea by Stephen Woodward, University
of North Carolina, Chapel Hill, NC] |

Freezer Over-Temperature Alarm - This electronic hobby circuit below is
designed to activate a beeper alarm, whenever the outside air temperature is below 0
degrees C (32F). A 9v battery powers the hobby circuit. The average 9ua
current is so low that the battery should last for many years.... [Hobby Corner

Freezing Temperature Alarm - This circuit turns on a beeper whenever the
outside air temperature is less than zero degrees Centigrade. The circuit draws
only a few microamps from a 9 volt battery. It uses a glass bead thermistor
accurate to 1 degree C.... [Hobby Corner Circuit by Dave Johnson] |

Network imitates thermocouples - 8-Nov-01 Issue of EDN Thermocouples
find widespread use for temperature measurement in systems. During system design or
testing, you must observe the system's response at different temperatures. However,
it's inconvenient to heat a thermocouple every time you need to check a system's
performance. You can use the simple trick of touching the thermocouple with a hot
soldering iron, but this method provides only.... [Design Idea by Abel Raynus,

Thermocouple Interfaces to Serial Port - 11/09/95 EDN-Design Ideas....The
circuit in Figure 1 acquires temperature data via an IBM PC serial port using a
thermocouple-based sensor. The sensor is a type-K (chromel-alumel]thermocouple. When
in contact, the dissimilar metals produce a potential difference that is a function of
temperature. Additional thermocouple junctions.... EDN is migrating links. This link
