High-end differential pressure transmitters for liquids and gases Deltabar PMD75B and PMD78B

Flow Optical analysis Level Liquid analysis System components Services Moisture Pressure Plant safety Digitalization Temperature

Application Thanks to their measuring ranges of between 1 mbar and 44 bar and process temperatures of between -70°C and +400°C, the new Deltabar PMD75B and PMD78B high-end differential pressure transmitters can be used in the most varied and toughest of differential pressure measurements: in conventional filter monitoring, in applications with extreme temperatures, for measuring extremely low differential pressures in towers, level measurements with the hydrostatic measuring principle or flow measurements using the differential pressure method. Advantages • Heartbeat Technology for device verification without process interruption and with predictive maintenance thanks to monitoring functions • Fast and wireless communication by Bluetooth® for easy commissioning, locking and documentation of the transmitter • Optical sensors in the display for user operation without opening the housing, including display color change from green to red in the event of a fault • CRC checksum provides at a glance assurance that the device configuration is correct • Undervoltage detection avoids dangerous plant conditions and the transmitting of frozen current values • Development to IEC61508 enables use in SIL2 and – with homogeneous redundancy – SIL3 applications At a glance • More productivity – Bluetooth® simplifies workflows such as commissioning or documentation of the measuring point • More process reliability – integrated undervoltage detection, CRC checksum, development to IEC61508 for SIL2/3 applications and digital assistants • More Industry 4.0 – integrated functionalities such as Heartbeat Technology enable further process optimizations in the context of Industry 4.0
