The LPA2 - Aviation Edition is a highly precise, lightweight & fully portable instrument designed exclusively for the Aviation

Industry.

It can automatically measure and display particulate contamination, moisture and temperature levels in various hydraulic uids.

The LPA2 - Aviation Edition can be connected to the MP range of bottle sampler products to enable laboratory based particle

counting.

Approved by Airbus, the LPA2- Aviation Edition is a solution for online monitoring of contamination in 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 - Aviation Edition is designed to measure and quantify the numbers of solid contaminants in Hydraulic, Lubrication and

Transmission applications. The LPA2 - Aviation Edition is designed to be a laboratory accurate instrument suitable for “on-site’’

applications utilising mineral oil as the operating uid. Please contact local sales ofce for other operating uid options.

The instrument uses the light extinction principle whereby two laser light systems shine through the uid and lands on photodiodes.

When a particle passes through the beam it reduces the amount of light received by the diode, and from this change in condition,

the size of the particle can be deduced.

Hydraulic and lubricating ystems consist 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 par- ticulate contaminants and these are ever present in all

hydraulic systems. There is a revised standard ISO cleanliness code ISO 4406 which classies the numbers of particles that can be

tolerated within the system and it is these levels of contaminants that the par- ticle counter is designed to measure.
