■ The mechanical pressure gauge of the HYDRA-Gauge is overpressure safe up to the
full scale value for a short term. However working pressure should not exceed 2/3 of the
measuring range to guarantee a long service life of the pressure gauge.
■ In any case the maximum pressures and temperatures of the process connection
according to the following chart must not be exceeded. The resulting maximum
permissible working pressures might be lower than the instrument's measuring range.
