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 pressure ranges from 6KPa to 3MPa (gauge pressure)
