Flush diaphragm type pressure gauge
Type: P757
 
Service intended
 
P757 series have diaphragm seal to be combined with a pressure gauge. These series are suitable to be used for the situation where corrosive, contaminated, hot, and viscous pressure mediums are present such as a chemical and food process.
 
Nominal diameter
 
63, 80 and 100 mm
 
Accuracy
 
63 and 80 mm : ±1.6 % of full scale
100 mm : ±1.0 % of full scale
 
Scale range (MPa, kPa, bar)
 
Refer to pressure unit and range table
Depending on diaphragm size and process conditions
 
Working pressure
 
Steady : 75 % of full scale
Over range protection : 130 % of full scale
 
Working temperature
 
Ambient : -20 ~ 65 °C
Fluid : Max. 100 °C
 
Temperature effect
 
Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
±0.5 % per 10 ℃ of full scale
