Reliable Solution for Heating/Air-Conditioning, Garbage Furnace and Water Supply & Sewage System Autonics is unveiling a smart pressure transmitter, PTF30 Series. PTF30 Series is a universal pressure transmitter that is highly reliable and economical. This series features diverse functions including input range selection function, TUF (Two Unit Function) and peak hold function to maximize users’ convenience.
Main features
• Best pressure transmission solution for small and middle sized project such as indoor heating and air conditioning, water and sewer, or incinerator, etc.
• Improves noise resistance and minimize effects by external disturbance
• Realizes high accuracy measurement by stainless steel diaphragm of pressure sensing part for various measured subjects
• 4-20 mA analog output (2-wire)
• Various functions :
User input range, display scale, output scale, digital fiter, multi-display selection, error display, TUF (two unit function), etc.
• Explosion-proof structure : Ex d ⅡC T6 (IP67)
