The unit of the measuring range above can be converted into kg/cm²、 MPa and kPa. Provide other measuring range according to requirements. Adjust requirements: lower range value (LRV) and upper range value (URV) can be adjusted within the scope of the upper and lower range limit, minimum measuring range≤| URV – LRV |≤maximum measuring range.
*Limit value of overpressure: depends on the pressure value of the parts with lowest pressure capacity
