Introduction of Pressure Switch

PTS71 pressure switch made by ORR’s own pressure sensor core as sensor sensitive element. Pressure transducer can be transferred liquid or gas pressure into the standard electrical output signal 4~20mA and 1 or 2 switching output, it also used for actual pressure measurement and OLED display at real time. 


Special features of Pressure Switch

·Wetted parts apply stainless steel ensure excellent corrosion resitance

·4 -digit digital OLED display

·24VDC excitation 

·Output 4~20mA, two setting points of switching output
