1 Warning - Read this first
Compressed air can be dangerous! Please familiarize yourself with the
forces under pressurized conditions. Respect the local guidelines and
regulations for working with pressurized equipment.
The pressure on the probe at 35 bar / 500 psi is around 40 Kilogram / 88
pounds force
! WARNING Mounting of this unit should be in De-Pressurized lines only !
Mount two safety chains, one to keep the probe in place, one for safety. Make
sure the hooks are completely closed. Make sure that the chains are strained as
these chains will keep the probe in position.
Use both safety eyes, to keep the force on the probe equal. Securing the probe
on one side will cause the probe to bend.
Use compression fittings with stainless steel ferrules. Please note that stainless
steel will permanently indent the probe and it cannot be used for any other
installation anymore.
Pressurize the system gently, 250 mbar per second. Fast pressurization may
result in shifting of the probe due to the pressure shock.
INSPECT the system after 30 minutes to see if the probe is still at the same
height. Systems with VIBRATIONS may be causing shifting of the probe.

2 Installation step by step
The following cartoons show how to install the probe in a 35 bar system. in addition to the
compression fitting with stainless steel ferrules (rated well over 35 bar) we recommend to use two
safety chains, for redundancy.

Compression fitting instructions
NOTE: the following instructions apply to stainless steel ferrules only. For use with teflon ferrules,
there are no specific guidelines. This is why we do NOT recommend to use teflon ferrules in high
pressure systems.
Step 1:
Before tightening the nut, mark the 6 'o clock position
Step 2:
When fixing, use a wrench. Tighten the nut 1 ¼ turns. The mark on the nut turns 1-1/4
and will end at the 9 o’clock pos ition. Make sure the probe stays aligned during the
process.
If not, gently loosen the nut, align the probe and tighten it again. Rough turning of the
probe can cause scratches in the stainless steel and this might result in leakage.
