Circuit provides cold junction compensation11/28/02 EDN-Design Ideas :
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 added

DPPs Make Nonvolatile MicroVolt DAC10/31/02 EDN-Design Ideas : 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.....(design idea added 2/05) |

Freezer Over-Temperature AlarmThis 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. ….(designed by David A.
Johnson) |
|
Freezing Temperature AlarmThis 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. ….(designed by David A. Johnson) |

Network Imitates Thermocouples11/08/01 EDN-Design Ideas : 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.....(design idea added 09/03) |

Thermocouple Interfaces to Serial Port11/09/95 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.....(design idea added 3/03) |
