The Deltabar PMD75 represents advanced electronic differential pressure measurement technology designed for precision level, volume, and mass monitoring in pressurized and closed tank systems. Unlike traditional differential pressure transmitters that use capillary lines filled with fluid, this innovative system employs two electronically connected sensors—one measuring high pressure and another measuring low pressure—eliminating common issues associated with temperature fluctuations and fluid fill degradation. This design breakthrough ensures minimal measurement drift over time while maintaining accuracy even in challenging process conditions. The transmitter supports multiple communication protocols including HART, PROFIBUS PA, and FOUNDATION Fieldbus, and complies with SIL2/3 safety standards for critical applications where failure is not an option.

This differential pressure transmitter finds extensive application across process industries where precise tank monitoring directly impacts operational safety, product quality, and regulatory compliance. In chemical processing plants, it provides reliable level measurement for reactors and storage vessels containing aggressive media. Oil and gas facilities utilize it for custody transfer applications and inventory management of hydrocarbons under pressure. Power generation plants depend on its accuracy for steam drum level monitoring, while pharmaceutical manufacturers trust it for bioreactor control in sterile processes. Food and beverage producers employ it for hygienic tank monitoring where cleanliness and precision are equally important.

The Deltabar PMD75 delivers significant business value through reduced total cost of ownership, enhanced process reliability, and minimized maintenance requirements. Its drift-resistant performance ensures consistent measurement accuracy over extended periods, reducing calibration frequency and associated labor costs. The elimination of capillary systems removes a common failure point in traditional DP transmitters, resulting in higher uptime and fewer process interruptions. Customization options allow for optimal integration into existing control architectures, while the robust construction ensures long-term reliability in corrosive or explosive atmospheres. These differentiators make it a prudent investment for businesses prioritizing operational excellence and asset protection.
