iCountPD Inline Particle Monitor - Deutsch DT Series, 0 to 5 V
Parker Hannifin’s icountPD represents the most up-to-date technology in solid particle contamination analysis. The icountPD is a compact, permanently-mounted laser-based particle detector module that provides a cost-effective solution to fluid management and contamination control.
The icountPD measures particle contamination continuously and updates the display, output options and limit relay every second.
Unlike the Parker CM20, LCM20 or MCM20, the unit does not perform a ‘one-off’ test. This means that even if the Measurement Period is set to 60 seconds, the display, output and limit relay all report the presence of dirt in the oil in just a few seconds - it does not wait until the end of the Measurement Period before reporting the result.
The icountPD has just one setting to control the accuracy, stability and sensitivity of the measurements and that is the ‘Measurement Period’. This can be set from five seconds to 180 seconds. The longer the Measurement Period, the more contaminant is measured, averaging out any spikes seen on a smaller sample. The shorter the Measurement Period the more sensitive the icountPD is to small slugs of contaminant, but also the performance on clean systems can be reduced. Thus, the user can select how sensitive the icountPD is to spikes of contaminant, and how quickly it responds to contamination levels above the set point (‘limits’).
With a Measurement Period of 100 seconds, the results will be for the last 100ml of oil that has flowed through the icountPD, updated on a second-by-second basis, giving an effectively continuous readout of the level of contamination.
