Temperature measurement systems for monitoring catalyst temperature are a vital aspect of a hydrocarbon reactor. The atypical reactor in a refinery such as a hydrotreater would employ such temperature measuring sensors in the catalyst bed, popularly known as Multipoint Reactor thermocouples.

Pyro Electric Instruments Goa, India, specializes in advanced multipoint temperature sensors for catalyst beds, by using the flexible multi-junction thermocouple technology to generate a profile of temperature. Such a technology can be employed in all the catalyst bed reactors for DHT, VGO, DHDS, and CCR plants.

Pyro Electric’s CATALYST PROFILER Multipoint Thermocouple Assemblies system consists of one or more thermocouple sheaths, which can provide between 2 to 9 measuring points on each sheath. Depending on the process connection flange size, the catalyst profiler can employ up to 10 thermocouple sheaths or 80 sensing points through one nozzle, and spread over the catalyst bed.
