Abstract (en)

[origin: DE10343457B3] The particle counter (22) may sense the presence of air bubbles (14) or solid particles in a viscous hydraulic fluid (12). A pump (16) draws fluid with particles or air bubbles from a tank (10) and passes it through a fluid line (18) to the input (20) of the particle counter. The particle counter may produce a signal every time an air bubble passes through. There is a spring-loaded non-return valve or control valve (28,30) downstream of the sensor, followed by a line (26) leading back to the tank. Flow and input pressure may be adjusted according to the temperature and viscosity of the fluid.
