MP04 All Stainless Steel Pressure Gauge - DIN Style Case & Ring | Miepl
                     MP04 ALL STAINLESS STEEL PRESSURE GAUGE
DIN Style Case & Ring
MIEPL make SS Pressure Gauges are based on the 
proven Bourdon tube measuring system. On 
pressurization, the deection of the Bourdon tube, 
proportional to the incident pressure, is transmitted 
to the movement via a link and indicated. The 
modular design enables a multitude of combinations 
of case materials, process connections, nominal sizes 
and scale ranges.
