Sanitary Pressure Transmitter HART Monocrystalline Silicon Type

The MG5700 sanitary pressure/differential pressure transmitter employs advanced ultra-pure monocrystalline silicon sensors for precise pressure-to-resistance conversion. Its proprietary packaging process features a liquid-contact diaphragm welded and polished to under 0.4 μm, complying with FDA standards for sanitary filling fluids. Designed primarily for the food and pharmaceutical sectors, it measures gauge, absolute, and differential pressure across gases, liquids, and vapors, while also supporting flow and level applications. The 4-20mA output is linearly proportional to the measured pressure, with optional HART protocol for flexible field configuration and high-precision measurement.
