Field of application
The high modular thermometer is used for several applications in almost all industries. Examples are heat exchangers, furnaces, dryers, process reactors, etc. With different head transmitter it’s a complete unit ready for use with enhanced measurement accuracy and reliability. It also enables very fast response times, due to direct contact measurement without thermowell. A variety of process connections and dimensions offer flexible application possibilities.
Magnesium oxide insulated thermocouples, commonly referred to as MgO thermocouples, are used in many process and laboratory applications. They have many desirable characteristics making thermocouples a good choice for general and special purpose applications. The sensors can be used on: Heat exchangers Power & recovery areasFurnaces DryersFlue gasCompressor stationsProcess reactors Metallurgical and glass manufacturing
