Examples of thermocouple


thermocouple isn’t in the Cambridge Dictionary yet. You can help!
To study the thermal structure associated with this periodic flow, a quincunical array of thermocouples was introduced into the fluid in the following manner.
The thermocouples were monitored with a multichannel computer data acquisition system.
Various materials for sampling tubes and for thermocouple sheaths were tested.
The holes as well as the thermocouple junctions were sealed by coating them with dissolved methyl methacrylate.
The output of the hot-wire amplifier vacuum thermocouple or the wave-analyser vacuum thermocouple was used as the second ordinate on the table.
To determine the heat flux and the temperature difference across the fluid layer, four pairs of copper-constantan thermocouples were used.
A thermocouple probe for measuring the temperature boundary layer above the ice was also mounted to the traversing head.
The five thermocouples, each 0.5 mm in diameter, extended 1.6 mm into the fluid.
This plug with the thermocouples replaced another plug without thermocouples at the centre of the upper plate bounding the fluid layer.
An oscillation in the temperature difference occurs as the knots pass by the thermocouples.
Direct solar heating of the exposed thermocouples was assumed to be negligible.
Visual observations were made using top-view and side-view shadowgraphs, while local temperature measurements were taken using a small movable thermocouple probe suspended on fine wires.
The diameter of the pseudostems at this height was wide enough (7-9 cm diameter) to hold these thermocouples.
By means of a rotary switch the emf's from each of the thermocouple pairs were sampled in turn (approximately once every minute).
However, the electrochemical potential was always deactivated during periods of thermocouple data acquisition.
On completion of thermocouple calibration the apparatus was levelled and assembled.
Good thermal contact is ensured by using epoxy paste mixed with aluminium powder as adhesive to affix the thermocouple beads into the plates.
The hot-wire output at a series of selected frequencies was recorded with the aid of the harmonic wave analyser and the vacuum thermocouple-microammeter combination.
