I don’t think there is one, I’m afraid.
I presume you’ve looked at the Shop page and the pictures. The emonTx is a box with four input sockets, 3 for c.t’s and one for an a.c. adapter that measures one phase voltage and serves as a (limited) source of power. If you go with Brian’s suggestion of Wi-Fi either with the ESP8266 or the RPi Zero W, then you’ll need a 5 V d.c. supply too. Depending on exactly what the control cabinets for your machines look like, you’ll either need to have panel space for these inside, or you may need an external (plastic) housing - especially if the Wi-Fi needs to get out of a metal cabinet, and of course 240 V, 13 A sockets.
Fitting the c.t’s is a matter of finding a place where the 3 phases are in separate cables. If you’re talking of under 32 A, I’d suggest the Talema AZ-0750 or the AZ-0500 from RS Components. They will likely require the leads extending and a 3.5 mm plug fitted, but they are smaller and being ring-core, should offer better performance than our “standard” split-core one. I haven’t tested one, though I can’t see RS stocking them if they’re not up to the job. The emonTx will need its calibration adjusted, but that’s a relatively simple matter and can be done in the 3-phase software before you load it (the emonTx comes with single-phase by default).
I must leave it to others to advise on getting the data into your system.
