PY300 Micro Diﬀerential Pressure Transmitter

PY 109 Micro pressure transmitter is a pressure measurement product specially developed for applications in the ﬁeld of micro pressure measurement. Ceramic sensor and integrated stainless steel fully sealed structure, small size, strong overload resistance, high stability, good corrosion resistance and reliable performance.
The pressure of the measured medium is transmitted through the ceramic diaphragm. The high-precision signal processing circuit is located in the stainless steel housing, which converts the sensor output signal into a standard output signal.

Applications:

■ Environmental protection, chemical, coating
■ Petrochemical industry
■ Power plant
■ Urban water supply
■ Hydro exploration
