The LD300 Series is a complete line of smart transmitters for differential, absolute, gauge,
high static differential pressure and flow measurement as well as models for level, remote
seal and sanitary applications. The LD300 Series is a robust and highly reliable solution
for your process. For flow measurement, the transmitter offers user selectable square
root function making it suitable for commonly used flow sensors. The large acceptance of
the LD300 line is due to the use of a capacitive cell as pressure sensor, which keeps the
digital signal from the pressure reading up to the transmitter output, increasing the device
accuracy and stability. For applications requiring the highest accuracy, the LD300 series
offer the model L1, with 0.04% accuracy. Three options of communications protocols for
configuration, monitoring and diagnostic are available: HART®, FOUNDATION? fieldbus
and PROFIBUS PA.
