The RT300 Series Transmitter is an extremely reliable multi-channel godet temperature measurement system. The digital transmitter circuit and digital controller interface circuit are immune to electrical noise and drift. Generous 9 mm clearance between the rotating and stationary parts eliminate rubbing and impacting - a cause of failure in other designs. The stationary electronics are housed in a small DIN-rail mount enclosure to remove them from the harsh motor environment. Models are available to accommodate from one to four RTD signals in a variety of mechanical configurations to fit most machines.

One-channel (RTD) system to replace Dienes-type transmitters. Includes speed and temperature signals. Multiple configurations available.
A true drop-in replacement rotating assembly for Rieter/SwissTex rotating transmitters. This rotor fits on J7-30, J7-31, and J7-32 roll motors.
This upgrade mounts in place of the original Rieter/SwissTex stator circuit board. The DS221 is capable 4-20mA or standard output.
Upgrade/conversion option for godet heater driver on Rieter extrusion machines. Mounts in place of original heater (replaces Rieter “orange box”).
