Series GGM • True Blue Gauge Guards
(Diaphragm Seals/Instrument Isolators)
Advantages:
- Low cost protection of gauges and other pressure instruments.
- Available in a variety of thermoplastics for specific chemical compatibility and temperature ranges.
- Increase product reliability and reduce system downtime caused by
failure of instruments not isolated by seals.
- Compact size makes these isolators ideal for limited-space installations.
- ±3% accuracy. Will handle most applications.
- Use with gauges, transducers, and pressure switches.
- Simple to fill and install.
- For use with highly aggressive or ultra-pure liquids.
- Diaphragm safety - If the gauge or instrument fractures while the system
is pressurized, the diaphragm will automatically seal against leakage
to the atmosphere.
- Standard PTFE diaphragm (except for vacuum and 0-15 PSI; 0-1 bar)
for maximum corrosion resistance.
- Eliminates need for costly exotic metal gauges for corrosive processes.
- Available with or without gauge (dual in PSI and bar).
- Optional transparent shield for external corrosion protection.
- Improved Design uses self-tapping fasteners.
