Euro gauge
Industrial service pressure gauge
Model : P252 series
Spec. sheet no. PD02-07
Service intended
P252 series are suitable for a corrosive environment.
Typical application includes: Chemical, petro-chemical,
refining process, power generation, marine and foods
industry. Its stainless case and cover have a good
appearance and the excellent proof against corrosive and
chemical attack.
Nominal diameter
63, 80, 100 and 160 mm
Accuracy
P2522 (63 mm) and P2523 (80 mm) : ±1.6 % of full scale
P2524 (100 mm) and P2526 (160 mm) : ±0.5 % of full scale
±1.0 % of full scale
Scale range (MPa, kPa, bar)
63 and 80 mm : -0.1 ~ 0 to 0 ~ 100 MPa
100 and 160 mm : -0.1 ~ 0 to 0 ~ 200 MPa
Working pressure
Steady : 75 % of full scale (63 and 80 mm)
100 % of full scale (100 and 160 mm)
Over range protection : 130 % of full scale
Working temperature
