Endress+Hauser Deltabar PMD55

Differential pressure

The Deltabar PMD55 sensor from E+H is a differential pressure transmitter and is equipped with a welded metal diaphragm and a piezoresistive sensor.

The device is widely used in all areas of production in the field of continuous measurement of the value of the differential pressure in gases, steam and liquids.

The presence of a menu with the function of measuring range adjustment makes it possible to quickly perform commissioning, reduce costs and save time. SIL2 in accordance with IEC61508/IEC61511.

Main advantages and technical characteristics of Deltabar M:

• Commissioning is carried out through the menu using PROFIBUSPA, FOUNDATION Fieldbus protocols , HART.
• Easily switch between low and high pressure chambers via electronic switch.
• Optimize spare parts stock and reduce costs through compact design and modularity.
<li >Availability of various certifications for almost all industries has made it possible to use these sensors all over the world.
• Threaded process connection.
• Temperature value: - 40 - + 85°C.
• Pressure value: 0.5 -  40bar.
• Error: 0.1%.
• International certificates for use in hazardous areas.
• Output signals: 4-20mA.    
• Power supply: 11.5V-45V DC.
