The LPA2 is a highly precise, lightweight & fully portable instrument suitable for on-site and laboratory applications. It can automatically
measure and display particulate contamination, moisture and temperature levels in various hydraulic uids. The LPA2 can be connected
to the MP range of bottle sampler products to enable laboratory based particle counting.
The LPA2 is a solution for online monitoring of contamination in your hydraulic uid, providing an immediate hydraulic health check. It
employs predictive maintenance procedures to help reduce downtime and in turn costs.

Product Presentation
The LPA2 is designed to measure and quantify the numbers of solid contaminants in Hydraulic, Lubrication and Transmission
applications. The LPA2 is designed to be a laboratory accurate instrument suitable for “on-site’’ applications utilising hydraulic uid
as the operating medium. Please contact your local sales ofce for other operating uid options.
The instrument uses the light extinction principle whereby two laser light systems shine through the uid and land on photodiodes.
When a particle passes through the beam it reduces the amount of light received by the photodiode, and from this change in
condition, the size of the particle can be deduced.
Hydraulic and Lubricating Systems consists of sets of continuously moving metal parts, which use hydraulic uid as the power
medium. Hydraulic uid is also used to create a lubrication lm to keep the precision parts separated and it is also used as a
cooling medium. The very nature of a hydraulic system is that it produces solid particulate contamination and these are ever
present in all hydraulic systems. There are various standards that quantify/ arrange/tabulate the amount of particle contamination
in specic volumes of uids and it is these levels that the particle counter is designed to measure.
Product features
Moisture sensor
LPA2-W models measure water content using a capacitive RH (relative humidity) sensor. The result is expressed as percentage
saturation. 100% RH corresponds to the point at which free water exists in the uid, i.e. the uid is no longer able to hold the water
in a dissolved solution. This is also normally the point at which signicant damage occurs in a hydraulic system, so is an ideal
measurement scale that is independent of the uid characteristics.
The water saturation point (100% RH) is temperature dependent, so the temperature is measured at the same time. This enables
results to be compared meaningfully.
The temperature measured is that of the uid passing through the unit.
Note: this may differ from that of the hydraulic system, depending on ow rate, pipe length and ambient temperature.
It is not intended to be an accurate indication of system temperature, but to provide a reference for the RH measurement at the
point of sample. Nevertheless, experience has shown the temperature measured is within a few degrees of that of the hydraulic
system, in most applications.

Data logger
The LPA2 includes a built-in data logger, which adds the facility to log and timestamp test results locally within an internal
memory, even when not connected to a computer.
• Test logging is determined by the log settings
• Each log entry is time-stamped and contains the LPA2 serial number, so that it can be identied later.
• The LPA2 memory has space for around 600 log entries. When full, the oldest log entry is overwritten.
Optional built-in pressure transducer
LPA20P & LPA2WP models measure system pressure at inlet of the unit via a built in 0-600 bar pressure transducer with a sensor
accuracy of +/-0.5% Full scale.
Optional on-board thermal printer
All LPA2 products come with an on-board printer.
Fluid compatibility product versions
Options within the product code allow for a tailored product to suit and be compatible for a range of uids.
M and MW version: Mineral and synthetic oils, plus diesel uids *
N version: Offshore/Subsea and water-based uids *
S version: Phosphate ester and aggressive uids. Contact local MP Filtri branch or distributor.
* Please note: a suitable ushing procedure should be followed when switch from mineral based to water based uids and vice
versa. See document # 200.093 on supplied USB data stick.
Please note: a bottle sampling unit will be required to carry out the ushing procedure.
