On the other hand, a liquid trap is essential between any liquid vacuum gauge and the manifold itself. The simplest accident can cause hours of needless delay as the vacuum line is cleaned out. Normally a simple splash trap is sufficient (see Sec. 7.4.6). Vacuum systems that go below 1CT5 torr should consider to have a cold trap placed between their liquid vacuum gauges and vacuum systems. This placement will keep vapors from contaminating either side of the system. 

The cut sheet may be manually inserted into the clamp frame of the thick-gauge thermoformer, but vacuum pick-up and placement devices are more common for long production runs. Pneumatic or mechanical tables are used to Uft very heavy or large sheets. Pneumatic clamp frame closures are usually... 

Vacuum gauge placement is important in establishing a reproducible process and the placement of vacuum gauging is important in system design. Vacuum gauges can oidy measure their surrounding environment.
