Thermo-Electra ML7038D Multi-Point Temperature Sensor With Spring Contact System
Product Code: ML 7038D
Manufacturer: Thermo-Electra
Thermo-Electra design, engineer, and manufacture Multipoint temperature sensors for industry and laboratory. These sensors are used to measure at several points over the length of the probe for temperature profiling or hot spot detection. The sensors can be used in reactor vessels, catalyst beds, crude oil refinement, test skids, and storage tanks for liquids and semi-solids such as grains and molasses/sugar syrup. The Multipoint temperature sensors assemblies / Multipoint RTD sensors up to 12 measuring points possible within a 3 mm sheath or 60 measuring points within an 8 mm outside diameter. An industrial reactor multi-spot thermometer can have up to 32 measuring points with the replacement of individual sensors on site. ATEX and IECEx certified sensors for use in Gas, zone 0, 1, and 2 with Exi, Exe, Exd, and Dust approval for zone 20, 21, and 22. An aluminum or stainless steel junction box can be added to accommodate a terminal strip or temperature transmitters.
