pressure

measurement range

（-100~0~10）KPa~250MPa

  When using a direct mounted flange diaphragm for remote transmission, the pressure ranges from 40KPa to 40MPa (gauge pressure) and from 40KPa to 1MPa (absolute pressure)

  When using a clamp type flange diaphragm for remote transmission, the gauge pressure ranges from 6KPa to 3MPa;
