Direct-reading pressure gauge PM82-4

stainless steel4-20 mAanalog output

The PM82-4 digital pressure gauge extends the standard model PM82 with a capacitive measuring cell.  The result is a finer measuring range with higher overload capability.  The  HD  version  in  particular is suitable for pressure peaks in fast-closing systems such as drinking water applications.  Its  large  and  bright  display  can  still  be  easily  read  from  a  distance  and  therefore  allows  for  a quick  assessment  of the  process pressure.  The analog output with  2  adjustable  switching outputs extends the range of applications.  Additional  process  connections  and  measuring ranges are offered in model PM82-3.  Our  modular design concept provides a wide variety of products.
