Differential pressure Deltabar PMD75
- SKU:
- Differential pressure Deltabar PMD75 series
- Weight:
- 0.00 Grams
Description
Application
The Deltabar PMD75 differential pressure transmitter, equipped with a piezoresistive sensor and welded metallic membrane, is designed for continuous measurement in liquids, gases, and vapors across a wide range of industries. Its 3-button interface ensures straightforward and dependable setup and operation. The built-in HistoROM data module simplifies the management of both process and device parameters. Engineered in compliance with IEC 61508, it is suitable for SIL2/3 safety applications.
It is ideal for level, volume, or mass measurement in liquids, differential pressure monitoring, as well as flow measurement (either volume or mass flow) when used in combination with primary elements in gases, vapors, and liquids.
- Process connections: Threaded
- Process temperature range: -40 to +85°C (-40 to +185°F)
- Measuring range: 0.25 mbar to 40 bar (0.0036 to 600 psi)
- Accuracy: ±0.05%, with optional "Platinum" accuracy of ±0.035%
- Certifications: International explosion protection, WHG overfill prevention, SIL, hygienic, and marine approvals
Benefits
