A thermocouple is made by joining together two dissimilar metals in a vee-junction.
This assembly is a heat to voltage transducer, when the junction is heated, a voltage appears across terminal A-B. This occurs becouse of a difference in the work function of the 2 metals forming the thermocouple.
This voltage is nonlinear at extremes, but it proves sonably linear in the center of its range.
Sensitive Instruments
Nature low range pressure sensors are very sensitive instruments and there a few factors that need to be considered prior to and during installation. They may look as robust as any other pressure sensor on the outside housed in a high IP rated stainless steel case, but inside there is a very thin diaphragm which is highly sensitive to acceleration and mechanical stress
Resolution
Resolution
The resolution of a sensor is the smallest change it can detect in the quantity that it is measuring. Often in a digital display, the least significant digit will fluctuate, indicating that changes of that magnitude are only just resolved. The resolution is related to the precision with which the measurement is made. For example, a scanning probe (a fine tip near a surface collects an electron tunnelling current) can resolve atoms and molecules.
