Differential pressure transmitter with metal sensor for measurement of pressure differences
差压变送器PMD75
应用领域
- The Deltabar PMD75 differential pressure transmitter with piezoresistive sensor and welded metallic membrane is used in all industries for continuous measurement in liquids, vapors and gases. The 3-key operation enables simple and reliable commissioning and operation. The integrated HistoROM data module allows easy management of process and device parameters. Designed according to IEC 61508 for use in SIL2/3 safety applications.
- For level, volume or mass measurement in liquids, differential pressure monitoring as well as flow measurement (volume or mass flow) in conjunction with primary elements in gases, vapors and liquids.
- Process connections: Threads
- Process temperature: -40 to +85°C (-40 to +185°F)
- Measuring ranges: 0.25mbar to 40bar (0.0036 to 600psi)
- Accuracy: ±0.05%, "Platinum" ±0.035% (optional)
- International explosion protection certificates, overfill prevention WHG, SIL, hygienic approvals, marine approvals
