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
