1) MWP = Maximum working pressure. → See also page 26, section "Pressure specifications".
2) FMD 77, FMD 78: The maximum pressure for the measuring device is dependent on the lowest-rated element, with regard to pressure, of the
selected components. → See also page 26, section "Pressure specifications".
3) The specified minimum operating pressure applies to the PMD 75 at the reference operating conditions for silicone oil. Min. operating
pressure at 185°F (85°C) for silicone oil: 0.145 psi
abs
(10 mbar
abs
). The pressure and temperature application limits of the selected filling oil
must also be observed for the FMD 77 and FMD 78. → See also page 46, section "Diaphragm seal filling oils".
4) Versions in the order code → See also page 53 ff, feature 40 "Measuring cell, nominal operating range, PN"
5) Minimum span that can be calibrated, turn down > 100:1 on request
6) 2320 psi (PN 160) versions with stainless steel M12 bolts, 6100 psi (PN 420) versions with steel M12 bolts, surface coating GEOMET
7) With copper seal: "MWP": max. 1450 psi (100 bar); "Overload on one side" and "Overload on both sides": max. 2175 psi (150 bar)
8) "–"side: 1450 psi (100 bar)
