(pressure diaphragm capsule element, )
Pressure diaphragm capsule elements serve as critical components in industrial instrumentation, enabling accurate fluid pressure measurement across sectors ranging from oil refineries to pharmaceutical manufacturing. These hermetically sealed units convert mechanical stress into measurable electrical signals through advanced strain gauge technology. Modern versions achieve ±0.075% accuracy even at 600°C operating temperatures, as demonstrated in 2023 ASME performance benchmarks.
Top-tier pressure diaphragm capsule elements employ cold-rolled 316L stainless steel diaphragms with 0.5μm surface finishes, reducing hysteresis to <0.01% FS. Comparative testing shows:
Feature | Standard Units | Premium Units |
---|---|---|
Cycle Life | 1.2 million cycles | 5 million cycles |
Thermal Drift | ±0.02%/°C | ±0.005%/°C |
Overpressure Safety | 300% FS | 500% FS |
