| Icon OBS Series diaphragm | PTFE Teflon bonded diaphragm | icon-process-controls-pressure.md |
| Icon OBS Series accuracy | ±0.75% | icon-process-controls-pressure.md |
| Icon OBS Series pressure range | 0-160 psi standard (OBS-V compound vacuum: -30 to 30 psi) | icon-process-controls-pressure.md |
| Icon OBS Series construction | PVC | PP | PVDF body, glycerin or silicone fill, 316SS movement | icon-process-controls-pressure.md |
| Icon OBS-TT feature | "Tell Tale" peak-hold pressure-spike indication | icon-process-controls-pressure.md |
The gauge-guard variant of this same line trades accuracy (±1.5% vs. ±0.75% direct-diaphragm) to keep a standard, cheaper 316SS/brass gauge movement fully isolated from the process fluid — a real accuracy-for-cost tradeoff worth flagging when a chemical-processing pressure point doesn't need direct-diaphragm precision.
A pressure gauge with a standard bronze or brass movement bonded directly against an aggressive process chemical corrodes from the inside before it ever shows a bad reading. Icon's OBS Series solves that with a PTFE Teflon bonded diaphragm across a corrosion-resistant PVC/PP/PVDF body — the OBS-TT variant adds a peak-hold indicator so an operator can catch a transient pressure spike after the fact.
