MPS 03.1

MPS 03.1 – Metal Particle Sensor

mps01_GL

General informations:
  • The metal particle sensor MPS 03.1 serves the purpose of detecting metal particles in moving hydraulic and
    lubricant fluids. Therefore, the sensor has to be installed permanently into the hydraulic or the lubricating cycle, so that the fluid, which is being monitored, is permanently flowing through the measuring channel of the sensor.
  • A standardised signal indicates that a metal particle was detected and has passed through the channel.
  • The standard signal is independent of the metal type and the accurate particle size.
  • The minimum particle size which can be detected is defined as an iron ball with a diameter of 350 μm at a volume flow of 60 L/min through the channel.

Typical applications of the sensor:
  • Inexpensive, continuous monitoring of large-scale gearboxes for incipient heavy wear with the increasing number of particles per time unit.
  • Monitoring component cleanliness, e.g. on flushing test stands.

Measuring principle of the MPS 03.1:
  • The measurement is based on a multiple inductor technique.
  • If passing through the system of inductors, metal particles will be detected with the help of a high frequency magnetic field.

* The minimum flow rate has to be ensured! Note: The working temperature range of the MPS 03.1 depends also on the VT – behavior of the fluid. For applications with very high viscous fluids a regular operation of the sensor is only possible within a temperature range in which a sufficient oil flow (> 60 l/ min.) can be ensured!
