In the menu TEST steam traps can be checked for loss of live steam – provided that data records and test tasks have been entered
previously on the PC. The test results will be saved.
Checking Steam Traps
Test
Note
Connect the measuring transducer VKPS 40Ex with the data collector (“Connecting and commissioning” see pages 0 – ).
When the data collector is ready for operation select the submenu Test.
The display will show the test tasks transferred from the PC to the data collector as well as their counting numbers, the associated plant
designation and the designation of the plant section.
■ During a test the measuring transducer VKPS 40Ex also measures the surface temperature of the steam trap. If the
service pressure prevailing at the place of installation has been specificied, the diagnostic system will be able to
identify the steam trap that causes the banking-up of condensate by comparing the boiling temperature associated
with the service pressure and the temperature measured at the steam trap.
(For more information see Online Documentation / Menu Test Objects / Creating Test Objects).
Attention
■
For a correct temperature measurement it is important that the surface of the reference point on the trap
where the tip of the measuring probe is applied is smooth and metallically bare. Otherwise considerable
deviations between the temperature reading and the actual temperature will be the consequence, resulting in
faulty analysis and incorrect evaluation.
