Laser particle monitors

The Stauff Laser Particle Monitoring, LPM 1 is a laser-based, four-channel, inline particle monitor designed for the continuous monitoring of particle contamination. The unit provides cumulative particle concentration information at >4 µm (c), >6 µm (c) and >14 µm (c) sizes applicable to the ISO 4406, ISO 11943 and ISO 11171 requirements for optical particle counters. A >21 µm (c) channel is also provided for larger particle concentration information. Machine operators are alerted to changes in particle contamination levels in a machine's fluid by the indications provided from the unit. The contamination level will be shown on the display or can be transmitted via the RS232 serial port into a personal computer. Also with the Modbus-serial port, the data can be transferred into a computer network or to an external display.

The system consists of a laser particle transducer (LPT) and a laser interface module (LIM). It is also necessary to configure the LPT particle sensor via an IR-port on a palm or pocket computer.
