Datasheet

Particle Monitor Patrick
Article number	3160-00-76.00
Device type	Optical particle monitor
Measuring principle	Light extinction
Description
Description	The Patrick particle monitor detects the contamination level and the trend of fluid purity. The particle monitor is calibrated with test dust in accordance with ISO 11943. Particle measurement is carried out according to the light extinction principle.
Cleanliness class indication	ISO 4406:99 SAE AS4059E NAS 1638 GOST 17216
Features
Output signal	4 to 20 mA
Operating hours counter	Integrated
Viscosity influence	Viscosity-independent with regard to the flow rate
Degree of protection	IP67
Display	± 90° rotating display
Function
Measuring setup	The particle monitor consists of a measuring cell, a laser beam and a photodiode.
Measuring principle	The laser beam passes through the measuring cell and hits the photodiode. If a particle crosses the laser beam, the intensity detected by the photodiode decreases depending on the size of the particle.
Designated Use
Application	Measurement of contamination in hydraulic and oil industry applications with non-aggressive fluids.
Benefit	Continuous monitoring of the purity allows changes in the machine to be detected very quickly.
