Temperature transmitters for head mounting and rail mounting are different in both their mounting method and their design. The functionality and performance, however, are the same for both types. Transmitters in head-mounted version are designed for installation in connection heads. There are two variants: either mounted directly onto the measuring insert or remotely inside the cover of the connection head. Temperature transmitters in rail-mounted version, also called DIN-rail mounting, are designed to be mounted onto DIN rails. They are suitable for use in control cabinets and can be mounted closely together, saving a lot of space. Whether a head-mounted or rail-mounted version is selected depends on the customer’s application.
