| |
|
| ● |
Metal Fasteners Have Been Eliminated to Prevent Corrosion in Volatile Atmospheres as well as Eliminate Mechanical Stresses. |
|
|
 |
|
| |
| |
| SOME COMPETITIVE ADVANTAGES TO CONSIDER ARE AS FOLLOWS: |
| |
| ● |
No
metal fasteners. Often in more sensitive environments these fasteners
can corrode. They also create stress points which, over time, can cause
premature failure |
| |
|
| ● |
Our
spherical upper chamber facilitates filling as the design provides for
natural venting of the air as the fill liquid displaces. |
| |
|
| ● |
The upper chamber also provides adequate volume for larger instruments and increased sensitivity. |
| |
|
| ● |
Our
contoured or convoluted diaphragm allows for sensitive transmission of
pressure as it offers no resistance to movement. The flat diaphragm
found in other units must stretch somewhat decreasing the accuracy of
the pressure transmission. For extremely sensitive applications, where
compatibility exists, our Viton diaphragm could be considered. |
| |
|
| ● |
Where
other gauge guards use an "O" ring to seal the instrument in the
instrument connection, we use a sealing NPT thread to properly seal.
"O" ring type designs cause a messy condition after filling and while
installing the instrument as the fill liquid is displaced around the
instrument thread and out and over the outside of the upper chamber. |

|
| SCOPE: |
|
| |
|
| ● |
The
Marquest Gauge Isolator provides two fluid chambers separated by an
impermeable membrane. The upper chamber (instrument side) is normally
filled with a stabilized liquid. The lower chamber receives the media
under pressure. |
| |
|
| ● |
Most pressure sensing devices are compatible with 1/4" FNPT outlet. The inlet is standard 1/2" FNPT or 1/4" FNPT. |
| |
|
| ● |
Chemical resistance and purity levels are as recommended for the base materials. |
| |
|
| ● |
No metals or lubricants are used in construction, internally or externally. |
| |
|
| ● |
Custom membranes may be supplied upon request. |
