The RT381-SP is a one-channel temperature measurement system designed as an upgrade for Teijin-Seiki STA transmitters to monitor and control temperature on heated godet roll shells on filament spinning machines. The system features generous 10 mm clearance between the rotating and stationary parts which eliminates damage due to impact and rubbing. TempTrak data communications technology is unaffected by dust or debris. Digital circuitry in the rotating transmitter and the stationary receiver are immune to electrical noise and drift. Fault detection modes protect heater from damage and expedite troubleshooting in the event of a sensor failure.
