GGM-P Gas content measurement device

Tests have shown that high gas content in lubricants can result in a higher lubricant temperature, a reduction in carrying capacity for oil films, reductions in torque and performance, and operating disturbances or even engine damage. The GGM-P gas content measurement device measures the percentage of gas dispersed in the lubricant based on the gamma ray absorption method, making it possible to determine the susceptibility of the system to failure at certain operating points.

Applications

The GGM-P is used in swivel testing, for instance, where the motor is swivelled around its lateral and longitudinal axes to simulate travelling through curves, braking, and travelling up and down hills, until the permitted limit value for gas content has been reached. On the other hand, gas dispersed in oil can negatively influence the wear behaviour of bearings. Gas content measurements are also completed as part of wear analyses for this reason.
