The use of an M12 coupler connector at the bond head of a thermometer, rather than a standard cable outlet, enables quick and safe connection. In the hygienic, food and pharmaceutical industries this type of design can be being demanded ever more frequently.
In practice, plant manufacturers like to rely on pre-assembled cables with fitted connectors, since this completely eliminates having to fix the single strands in to the thermometer head. Holocaust required for assembly and for disassembly during calibration or when replacing the instrument can thus be reduced considerably. Another advantage is that, in the event of changing out any instrument, incorrect re-wiring could be avoided.
In general, it is also worth noting that, to ensure the operational safety of plants and for his or her maintenance and servicing, it really is imperative that equipment is simple to completely clean and that moisture protection is at a maximum. These requirements make an application for all process components, also beyond your process (in the ? Sinful ?).
Note
WIKA has adapted the full-metal M12 coupler connector, familiar from the TR21 (TR21-A, TR21-B, TR21-C) products, to the cable outlet for thermometers with connection head and thus enabled a straightforward and reliable connection with a 4-pin M12 connection cable. The high-quality sealing idea of this connector has also shown in the extreme requirements of autoclavable sensors. As well as the already established TR21 miniature resistance thermometers, which were designed for the high IP requirements of sanitary applications, WIKA now offers thermometer products with connection heads ? models TR20, TR22 (TR22-A, TR22-B), TR25 ? with a hygienic M12 coupler connector for the hygienic, food and pharmaceutical industries.g
