The usage of an M12 coupler connector at the connection 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 a lot more frequently.
Used, plant manufacturers like to rely on pre-assembled cables with fitted connectors, since this completely eliminates having to fix the single strands into the thermometer head. The time required for assembly and for disassembly during calibration or when replacing the instrument can thus be reduced considerably. Another advantage is that, in case of changing out any instrument, incorrect re-wiring can be avoided.
In general, additionally it is worth noting that, to ensure the operational safety of plants and for their maintenance and servicing, it really is imperative that equipment is easy to completely clean and that moisture protection is at a maximum. These requirements apply for all process components, also outside the process (in the ? diaphragm seal ?).
Note
WIKA has adapted the full-metal M12 coupler connector, familiar from the TR21 (TR21-A, TR21-B, TR21-C) product line, to the cable outlet for thermometers with connection head and thus enabled a straightforward and reliable reference to a 4-pin M12 connection cable. pressure gauge 10 bar -quality sealing idea of this connector in addition has shown in the extreme requirements of autoclavable sensors. As well as the already established TR21 miniature resistance thermometers, that have been 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.
