Fluid management / oil maintenance
The role of oil condition sensors is becoming increasingly important in hydraulics. Around 70-80% of hydraulic failures are caused by contaminated fluids. Dirt particles are often introduced from outside and continuously deteriorate the cleanliness of the oil. Contamination of the oil has a negative impact on the service life of hydraulic components. In proportional control valves, a small particle can cause the valve to malfunction. A pump or valve failure usually leads to machine downtime with disastrous consequences and costs. Clean and dry oil ensures that the hydraulic system functions properly and reliably. With the help of oil condition sensors, you can continuously monitor the contamination of hydraulic oil. This allows intervention in the hydraulic system as soon as the oil quality deteriorates.
In our Fluid Care category you will find further helpful information on this topic.
Optical particle measuring devices - Particle counters for continuous measurement of contamination in hydraulic fluids
Optical particle counters work with a so-called “light blocking method”. The medium being examined is illuminated using LED or laser light. The particles to be counted are individually measured optically and then electronically evaluated using a numerical method. The number and size of particles are analyzed continuously, automatically and almost in real time using particle counters. This ensures complete documentation of the conditions according to purity class so that changes can be responded to in good time.
It is important to monitor the condition of hydraulic fluids, as over 80% of failures are due to particle contamination. Hydraulic oil must be examined for its actual level of contamination, as filter performance requirements vary depending on environmental conditions. Taking the oil from the plant and examining it under a microscope is both inaccurate and very time-consuming.
Particle counters continuously monitor the hydraulic oil, so that if the oil purity deteriorates, quick action can be taken, for example to change the hydraulic filters.
Oil condition sensors - Electrical measuring method for determining oil quality
Oil condition sensors or oil quality sensors provide real-time monitoring of the actual contamination and water content in the oil. The oil condition sensor is an inexpensive solution for permanent monitoring of the oil condition in hydraulic systems, combustion engines or lubricating oil systems. The need for effective monitoring of critical systems and machines is becoming increasingly important:
Constantly rising crude oil prices are increasing the cost of oil changes. By permanently monitoring the hydraulic system, oil change intervals can be delayed and carried out as required.
The requirements for the hydraulic medium are constantly increasing, because better oil quality can increase the service life of (hydraulic) systems.
The measuring method of most of these sensors is based on measuring the dielectric constant. Our OQS also measures the so-called “effective resistance”, which makes the sensitivity of the sensor approx. 30 times greater than that of conventional oil condition sensors.
Argo Hytos particle counter
ARGO-HYTOS hydraulic filter elements meet the highest standards of performance and quality. Only original parts guarantee that a reliable level of performance can be maintained. We have been a long-standing partner of ARGO-HYTOS, and you will find a large number of filter elements with us, also in exchange for other manufacturers.
Argo Hytos oil condition sensor
The LubCos H2O+ II is a stationary screw-in sensor for the continuous determination of the oil condition. It also determines the oil moisture and the temperature in hydraulic and lubricating oils.
LOQS oil condition sensor
With the oil quality sensor you gain control over real-time monitoring of oil deterioration, oil condition and water ingress. Expensive oil changes are therefore based on the oil condition and not on a historical schedule. The OQS oil condition sensor detects all types of wear and contamination:
• Water
• Acid
• Fuel
• Viscosity
• Different types of oil
• Carbon
• Particles
Other advantages of the OQS oil condition sensor:
• Oil quality changes are detected with a sensitivity of 0.01% (10ppm) with an accuracy range of +/-0.5%. recognized.
• The OQS continuously analyzes the oil condition of the system and reports every two seconds.
• Proven worldwide for use in even the most extreme industrial environments.
• Quick and easy to install on any system with plug & play integration
MP Filtri particle counter
The ICM 2.0 is an inline particle counter with LED measuring technology. This particle counter is used to automatically measure the solid contamination, temperature and relative humidity of hydraulic fluids. The ICM is intended for permanent use and is permanently installed in a hydraulic circuit.
The ICM can be operated both manually on the device and via a remote control (using a PC, laptop, tablet). The device can be controlled externally via a second signal connection. It remains integrated into any system control system. The ICM 2.0 works with a unique LED measuring technology, and the advanced measuring cell enables an even finer resolution in particle counting.
Advantages:
• continuous measurement / analysis of the oil purity of hydraulic systems
• suitable for areas where there is little installation space
• cost-effective measurements can be carried out
