MP37 SS Case Brass Pressure Gauge - DN100 | Miepl
                     MP37 SS CASE BRASS PRESSURE 
GAUGE
DN100
MIEPL  make SS Case Brass Pressure Gauges are 
based on the proven Bourdon tube measuring 
system. On pressurization, the deflection 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.
