The RT310 Series Transmitter is an extremely reliable multi-channel temperature measurement system for the calender industry. 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 calendering environment. Models are available to accommodate from one to four RTD signals in a variety of mechanical configurations to fit most machines.
