Arni, Switzerland and ZIJTAART, the Netherlands --- Exergen Global announces that TomTom-Tools is employing its micro IRt/c-K as part of a customized solution to help its cement manufacturing customers maintain ideal operating temperatures and increase production. Rotary kilns, used in cement manufacturing, must maintain a very specific temperature range to prevent damage to the refractory stones inside the kiln and to ensure optimal cement mixing temperature. TomTom-Tools selected Exergen’s micro IRt/c-K for the task because the non-contact sensor employ Exergen’s patented heat-balance technique to provide the industry’s most accurate and reliable non-invasive temperature measurement.
TomTom-Tools engineers integrated the Exergen micro IRt/c-K into their Ovality Sensor, a one of a kind tool that is fixed to the exterior of the kiln and that helps extend refractory life by measuring stress in the kiln shell during operation. From outside the kiln, Exergen’s sensor employs the heat balance technique to accurately detect the kiln’s interior temperature, and both the Ovality Sensor and the Exergen Sensor send measurements to a personal computer using a Bluetooth connection. The Exergen sensor solution employs a PID controller to continuously calculate the difference between the desired and measured interior temperature and takes corrective action to maintain the optimal setting.
