Product Overview
The G-75 PTF30 Series Pressure Transmitters offer minimized disturbance effects through improved noise resistance and excellent corrosion resistance with a stainless steel housing. These high-accuracy transmitters boast a 0.3% F.S. accuracy and a wide range of functions including user input range, display scale, output scale, digital filter, multi-display selection, abnormal operation display, and TUF (Two Unit Function). They are suitable for applications such as indoor heating, water supply and sewage, and incinerators, particularly for small and medium-sized projects. The series features explosion-proof specifications (Ex D IIC T6) and IP67 protection structure (IEC standard).
