Tri-Clamp
The clamp connections are suitable up to a maximum pressure of 16 bar (232 psi). Please observe
the operating limits of the clamp and seal used as they could be under 16 bar (232 psi). The clamp
and seal are not included in the scope of supply.
Secondary containment
pressure rating
The sensor housing is filled with dry nitrogen and protects the electronics and mechanics inside.

If there is a risk of measuring tube failure due to process characteristics, e.g. with corrosive
process fluids, we recommend the use of sensors whose secondary containment is equipped
with special pressure monitoring connections (order code for "Purge connection", option CH).
With the help of these connections, the fluid collected in the secondary containment can be
bled off in the event of tube failure. This is especially important in high-pressure gas
applications. These connections can also be used for gas purging (gas detection).
Do not open the purge connections unless the containment can be filled immediately with a
dry, inert gas. Use only low gauge pressure to purge. Maximum pressure: 5 bar (72.5 psi).
If a device fitted with purge connections is connected to the purge system, the maximum
nominal pressure is determined by the purge system itself or by the device, depending on which
component has the lower nominal pressure.

Flow limit Select the nominal diameter by optimizing between the required flow range and permissible pressure
loss.
