DensityPRO-C Thermo Scientific - Process Systems

From refining and mining to pulp and paper, the DensityPRO-C is an economical and versatile nuclear density gauge designed for rugged industrial applications. It uses ionizing radiation to accurately and reliably measure the density of process material in both horizontal and vertical pipes that range in size from one inch (25.4 mm) to 40 inches (1020 mm). An extremely small nuclear source and a scintillation detector, are mounted externally to provide highly accurate, non-contacting density measurement. Depending on the application, the source size may vary slightly based on the pipe size, wall thickness, process material and the precision required.

The DensityPRO-C detector features surface-mounted electronics. Due to their compact size, the electronics endure high shock and vibration and have proven to withstand a minimum of 11 G's at 40 Hz over an extended timeframe with no adverse effects, ensuring the dependability of the gauge over the long run. In addition, the multiprocessor-based electronics ensure uninterrupted output during data entry. All user data is doubly stored in non-volatile memory with no battery back-up required.

Because density measurement may be affected by temperature, the detector can be equipped with an optional temperature compensation board and a resistive temperature device (RTD). When connected to the detector, the RTD allows the temperature readings to be input to account for temperature fluctuations.
