‘Deltadyne’ Differential Pressure Devices
Differential Test Unit - 0309
Introduction
To optimise element service life and economy, ‘Pall’ ‘Deltadyne’ differential pressure
devices should be checked if doubt exists as to their operation to signal filter element
clogging condition. The Pall Deltadyne differential pressure device testing unit is
suitable for testing all ‘Deltadyne’ visual indicators and electrical switches. The unit is
supplied complete with an integral electrical circuit and suitable leads for checking the
operation of both normally open and closed connections of switches. Full operating and
service instructions are included.
The unit is made of corrosion resistant materials and is light and easy to handle.
To test a Pall Deltadyne differential pressure device, simply remove the blanking plug
from the tester and replace with the device to be tested, ensuring it is tightened to avoid
leaks. For visual indicators, slowly screw in the tester’s piston to increase pressure until
the device operates and registers the pressure signal setting on the gauge. For
electrical switches, install the device similarly, connect the appropriate lead and the
green light will illuminate when the test button is pressed. As the tester piston is
adjusted to increase pressure, the switch will operate, extinguishing the green light and
illuminating the red light, verifying correct operation of the switch. The gauge again
registers the signal setting of the switch.
