General Care
Your digtal pressure gauge is very low maintenance and will need little care, as long as it was
installed correctly. However, in general, you should:
•
Keep the gauge and the area around it generally clean.
•
Avoid applications for which the gauge was not designed, such as extreme temperatures,
contact with incompatible corrosive chemicals, or other damaging environments.
•
Inspect the threads whenever you remove the gauge from duty or change its location.
•
Avoid touching the diaphragm. Contact with the diaphragm, especially with a tool, could
permanently shift the output and ruin accuracy.
•
Cleaning the diaphragm or the diaphragm bore should be done with extreme care. If
using a tool is required, make sure it does not touch the diaphragm.
•
If air bubbles form under the plastic facing of the gauge, unscrew the plastic ring and lift
the plastic facing off the gauge. The plastic film can be discarded.

Removal Instructions
Removing your PG2 from service must be done with care. It’s easy to create an unsafe situation,
or damage your sensor, if you are not careful to follow these guidelines:
•
Make sure the pressure is completely removed from the line or vessel. Follow any and all
procedures for safely isolating any media contained inside the line or vessel.
•
Remove the gauge with an appropriately sized wrench (7/8” hex).
•
Carefully clean the gauge’s fitting and diaphragm of any debris (see General Care) and
inspect for damage.
•
Store your gauge in a dry place, at a temperature between -40° F and 180° F.
DANGER
: Removing the pressure gauge while there is still pressure in the line or vessel
could result in injury or death.
IMPORTANT
: Any contact with the diaphragm can permanently damage the gauge. Use
extreme caution.
IMPORTANT
: Do not re-zero display while gauge is installed. Always ensure diaphragm
is exposed to atmosphere before re-zeroing.
