PSD90-3 Fuel Quantity Test Set
The PSD90-3 will test any AC or DC capacitive fuel, water, liquid oxygen (LOX), or engine oil system.
When combined with an aircraft specific interface, the PSD90-3 allows the user to test, troubleshoot and isolate fuel system issues, calibrate fuel quantity indicators, and detect contaminated fuel probes.
Developed for use in all environments the PSD90-3 is ideal for flight line testing on battery power or bench testing on external power.
Contaminated Probe Testing
The PSD90-3 provides users with two methods; Auto and Manual, for detecting and isolating contaminated fuel probes caused by particulates, water, microbial growth, or other sources of contamination.
During normal capacitance measurements, the contaminated fuel probe detection function will automatically alert the user via a Degree of Error indication on the display and with a Contaminated Fuel Probe Detected LED on the front panel.
Once there is an indication of possible probe contamination, the user can manually test using the Check Probe function with a user-selectable Percent of Error limit which will illuminate the Contaminated Fuel Probe LED indicator if exceeded.
Aircraft Specific Interface
Each aircraft platform requires a unique interface to access the FQIS. The complexity of the fuel system determines the capability of the interface to allow for complete testing of the fuel quantity system. Contact VIAVI for the proper interface for your aircraft.
