BRG 3000 Overview
The Model BRG 3000 is a bench top system for measuring the Torque characteristics of Anti Friction Bearings-滑动轴承 and Bearing Assemblies-轴承组合件. Contained in the system are a customized computer, monitor, keyboard, and the necessary circuitry for performing a test and processing the results. User-friendly menus enable the operator to rapidly become proficient with the operation of this National Instruments Labview based system.
Standard features such as 2 serial ports, one parallel port, a diskette drive and a CD ROM drive are provided. 标准接口驱动系统
Test configurations are stored in memory and are retrievable with the click of a mouse key, avoiding time consuming setups. Test results can be stored in memory or on a disk and then transported to other peripheral devices for further analysis and processing. 试验操作简单，数据储存处理和分析系统
Testing Capabilities 测试范围及能力
Both starting torque-启动扭距 and running torque-转速扭距 can be measured with the same system, the same tooling and in the same test cycle.

 Temperature Environment: 60 to 90 degrees F.
 Humidity Environment: Up to 95 % non-condensing.

Test Head: A Vibrac Model 9405A test head is the mechanical testing portion of the BRG 2000 Bearing Test System. This test head combines an Optical Torque Transducer光学扭距传感器, an Optical Encoder光编码器 and a Variable Speed Synchronous Drive. This combination enables the system to rotate the bearing at a constant and precise speed while measuring both torque and position.
Torque Transducer: A Vibrac Mini Series Static torque transducer is used in this test head.
