Checking steam trap
DANGER
Risk of explosion if the pipeline to be
tested is carrying voltage.
Before starting the test make sure that
no part of the pipeline is carrying
voltage.
You can achieve this e.g. by earthing the pipeline.
DANGER
Risk of explosion due to spark-over.
Do not use any items in the explosion-
risk area that could generate sparks.
Do not use the supplied file!
In the VKP 42 app, select a steam trap as the
test object.
Make sure that there is no paint or dirt on the
measuring point.
Make sure that you use the same measuring
point as for previous tests.
If necessary, mark the measuring point on the
steam trap.
You can use the identification signs to ensure the
test object has the same details as the data
collector.
Attention!
If the measuring probe does not touch the
trap firmly at the right position and angle
the readings may be incorrect.
Make sure the sensor tip of the
measuring probe touches only a bare
metallic surface.
Make sure the sensor tip touches
always the same test point.
Make sure the sensor tip is
perpendicular to the surface of the
steam trap when it touches the test
point.
For thermal steam traps, you must apply the sensor
tip in one of the following positions:
Where the cover meets the flange
On the side of the cover
Example points of application for thermal
steam traps
