  • Mã SP:
  • Giá : Liên hệ
  • P258 series are suitable for corrosive environments. Typical application includes : Chemical, petro-chemical, refining process, power generation, marine and food industry. The filled liquid absorbs vibration and pulsation.

Nominal diameter 63, 80, 100 and 160 mm
Accuracy P2582 (63 mm) and P2583 (80 mm) : ±1.6 % of full scale
P2584 (100 mm) and P2586 (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
Filling liquid Glycerin
Working temperature Ambient : -20 ~ 65 ℃ (With glycerin filling)
               -40 ~ 65 ℃ (With silicone filling)
Fluid : Max. 100 ℃ (With glycerin filling)
          Max. 100 ℃ (With silicone filling)
Degree of protection EN60529/IEC529/IP67
Temperature effect Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
±0.4 % per 10 ℃ of full scale
