3 Product description

3.1 Equipment architecture

The multipoint thermometer belongs to a range of modular product configuration for multipoint temperature detection with a design where subassemblies and components can be managed individually for easy maintenance and spare part ordering.

The temperature probe-only version consists of many sub-assemblies:

• Insert

• Rope

• Weight

• Process connection

• Neck (see below for a more detailed description)

In general the instrument measures the temperature profile inside the process environment by means of many sensors wrapped around a rope, jointed to a suitable process connection which ensures the right tightness level.

The temperature probe + diagnostic version combines the temperature probe with a head transmitter, which is available with enhanced accuracy and reliability compared to directly wired sensors. Output communication protocols available are: Analog output 4 to 20 mA, HART®, PROFIBUS® PA, FOUNDATION Fieldbus™. Externally the extension cables are wired into the junction box, which can be directly mounted or remotely as an option.
