En Instrumentación industrial, los termopares son ampliamente usados como sensores de temperatura. Son económicos, intercambiables, tienen conectores estándar y son capaces de medir un amplio rango de temperaturas. Su principal limitación es la exactitud ya que los errores del sistema inferiores a un grado Celsius son difíciles de obtener.
El grupo de termopares conectados en serie recibe el nombre de termopila. Tanto los termopares como las termopilas son muy usados en aplicaciones de calefacción a gas.
EN INGLES:
A thermocouple (also called thermocouple) is a transducer formed by the junction of two dissimilar metals that produces a voltage (Seebeck effect), which is a function of the temperature difference between one end called "hot spot" or hot junction or measure and the other called "cold spot" or cold or reference junction.
In Industrial instrumentation, thermocouples are widely used as temperature sensors. They are cheap, interchangeable, have standard connectors and can measure a wide range of temperatures. Its main limitation is accuracy as the system errors of less than one degree Celsius are difficult to obtain.
The group of thermocouples connected in series called thermopile. Both thermocouples and thermopiles are widely used in gas heating
