FFThermo Scientific* Ramsey Series 14 Belt Scale System is specifically designed for high accuracy or basis-of-payment applications requiring certification by government and regulatory agencies.
It incorporates the Ramsey 10-14 low-deflection, full-floating unitized weighbridge and the Ramsey 61-12C belt speed sensor. Both are well-proven on hundreds of precision belt weighing installations. It also utilizes the Ramsey Micro-Tech 2301 or 3301 electronic integrator and the Ramsey 2301-D load cell exciter/digitizer, which are the products of 50 years of design and application experience with high-accuracy belt scales.
Warranty and Service Offering: On factory-approved installations, we guarantee that the Thermo Scientific Ramsey Series 14 Precision Belt Scale System will weigh and totalize to a value within ±0.125% of the test load at flow rates between 25% and 100% of the scale system's calibrated capacity when calibrated against an actual weighed material test. Furthermore, we warrant that the scale system will repeat to within 0.1% of consecutively run, simulated calibration tests.
Certifications: Certificate of Conformance in the United States as issued under the National Type Evaluation Program (NTEP) of the National Conference on Weights and Measures. Outside of the US, it is certified by OIML and EEC Class I standards.
Recommended for: Loadout, inventory monitoring and fee-holder type applications requiring certification.
