Description
The LRT2000 is a rugged, easy
to use instrument designed to
provide applied pressure control
and rate of pressure decay
leak testing. Simple controls
enable the user to pressurise a
component to be tested, then
isolate it from the supply pressure
and measure rate of pressure
decay. A dual channel
display indicates pressure and
rate of pressure change simultaneously.
Automated PASS or
FAIL indication is available as an
option.
Operation
The instrument should be connected to a 120 - 240 VAC, 50/60
Hz power supply and a
clean dry gas source, A period of 60 minutes should be allowed after
powering the instrument
to allow it to stabilise and reach optimum accuracy.
Test pressure to be applied is set using the manual pressure regulator.
A single rotary valve
allows selection of FILL, TEST and VENT modes, neatly eliminating the
possibility of pressurising
a component with a vent valve open, or conversely, venting a component
whilst it
is still exposed to the pressure source. In the test mode the actual
rate of pressure change
is compared to the component specification to provide an unambiguous
pass or fail
decision.
