LD300 Series

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 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

Three options of communications protocols for configuration, monitoring and diagnostic are available: HART®, FOUNDATION™ fieldbus and PROFIBUS PA

• ± 0.075% accuracy for standard models;
• ± 0.040% accuracy for L1 models (high performance);
• ± 0.2% of URL stability - Guarantee for 12 years;*
