1) MWP = Maximum working pressure. → See also page 26, section "Pressure specifications".
2) The specified overload only applies to the measuring cell. The maximum pressure for the measuring device is dependent on the weakest element,
with regard to pressure, of the selected components. → See also page 26, section "Pressure specifications".
3) Min. operating pressure at the reference operating conditions for silicone oil. Min. operating pressure at 185°F (85°C): to 0.145 psi

Explanation of the term 'Turn down (TD)'
(TD = turn down)
Turn down = nominal value/set span
