Correction of thermal gradient errors in stem thermocouple hygrometers.
Stem thermocouple hygrometers were subjected to transient and stable thermal gradients while in contact with reference solutions of NaCl. Both dew point and psychrometric voltages were directly related to zero offset voltages, the latter reflecting the size of the thermal gradient. Although slopes were affected by absolute temperature, they were not affected by water potential. One hygrometer r...
متن کاملThermocouple Measurement
In 1822, Thomas Seebeck, an Estonian physician, accidentally joined semicircular pieces of bismuth and copper (Figure 1) while studying thermal effects on galvanic arrangements. A nearby compass indicated a magnetic disturbance. Seebeck experimented repeatedly with different metal combinations at various temperatures, noting relative magnetic fi eld strengths. Curiously, he did not believe that...
متن کاملA Universal Ethernet Thermocouple Scanner
The growing use of Ethernet interfaces in Aerospace and Industrial Process applications has created a need for an Intelligent Thermocouple Scanner to operate on an Ethernet network and complement Intelligent Pressure Scanners. The scanner must be able to accept several different thermocouple inputs, convert the signals to engineering units using NIST tables and output the data over a TCP/IP Eth...
متن کاملA thermocouple for the brain.
IT seems ludicrous that the reading of a rectal thermometer should be taken as a guide for deciding how long a major cerebral artery may be safely clamped by a neurosurgeon. Although the temperature of the brain must approximate that of the blood passing through it, temperature gradients are present throughout the body during hypothermia and the reading on the thermometer will vary with the dis...
