Field of application
The Deltabar PMD55 differential pressure transmitter with piezoresistive sensor and welded metallic membrane is typically used in process or environmental applications for continuous measurement of pressure differences in liquids, vapors and gases. Quick Setup with adjustable measuring range allows simple commissioning, reduces costs and saves time. SIL2 according to IEC 61508 / IEC 61511.
For level, volume or mass measurement in liquids, differential pressure monitoring, e.g. of filters and pumps 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: 0.5mbar to 40bar (0.0072 to 600psi) 
- Accuracy: ±0.1%, "Platinum" ±0.075% (optional) 
- International explosion protection certificates, SIL 
Benefits
- Easy menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus 
- Easy process adaptation to impulse line high-pressure/low-pressure change via electric switch on the main electronics
