Product Overview
The G-75 PTF30 Series Pressure Transmitters are designed for high-accuracy pressure measurement with minimized disturbance effects due to improved noise resistance. Featuring a robust stainless steel housing for excellent corrosion resistance, these transmitters offer a high accuracy of 0.3% F.S. They come equipped with a variety of functions including user input range, display scale, output scale, digital filter, multi-display selection, abnormal operation display, and Two Unit Function (TUF). The series includes explosion-proof specifications (Ex D IIC T6) and an IP67 protection structure. Ideal applications include indoor heating, water supply and sewage systems, incinerators, and small to medium-sized projects.
