MD-G103 miniature pressure transmitter
Precision laser welding diffusion silicon sensor, precision pressure transmitter
Product details

The MD-G103 series miniature pressure transmitter adopts a diffusion silicon pressure sensor as the sensitive element, combined with a compact structure and digital circuit design, and uses integrated laser welding technology to make its structure small and resistant to vibration and impact.
This series of transmitters can meet a wide range of 60kPa~100MPa, with multiple output methods such as mini Hosman/M12 aviation plug/direct output, and 4-20mA/0-5V/0.5-4.5V/0-10V, making this series of products have good applicability in many industries.
This transmitter can be used with various types of frequency converters, air compressors, hydraulic presses, hydraulic stations, automated production lines, and automation equipment.
