Improve Process Throughput and Quality with Temperature Transmitters
It is important to have accurate and reliable temperature measurements to maintain quality of roasted products. Historically, slip rings have been used to measure temperature in rotating roasters. Slip rings can become oxidized over time, and replacement requires a roaster shutdown and inspection. To alleviate the challenges of using a slip ring, Rosemount™ 648 Wireless Temperature Transmitters coupled with Rosemount 214C Temperature Sensors can be used to measure the surface temperature of the roaster. The transmitters communicate temperature readings back to the control system to help maintain product quality and avoid a process shutdown that would be required with using slip rings. This solution also vastly improves process throughput and decreases maintenance costs.
