The microprocessor control unit automatically regulates the necessary power to the solder pot furnace by monitoring a type J (Iron-Constantan) thermocouple.
The exhaust gas temperature (EGT) is measured with thermocouple made of iron and iron-constantan. Pollution levels of smoke and oxides of nitrogen (NOx) are recorded by AVL smoke meter and Netel Chromatograph NOx analyzer respectively at the peak load operation of the engine.
The junctions of Iron-Constantan thermocouples are fixed inside a small diameter copper tube.
The temperature of the contents of the cell was measured by a calibrated iron-constantan thermocouple and the pressure in the cell was measured by digital Heise gauges (0-10, 0-35 MPa).
Calibrations include Chromel-Constantan, Iron-Constantan, Chromel-Alumel, and Copper-Constantan.
The temperature is measured with an iron-constantan thermocouple and a voltmeter.
The curite combination sensor is comprised of an Interlink force-sensing resistor to determine pressure, and an iron-constantan thermocouple that measures temperature.
