AHD- S 201 Hydrostatic Level Transmitter for Shipbuilding and Offshore AHD-S 201 Hydrostatic Probe For Marine And Offshore Ceramic Diaphragm Accuracy according to IEC 60770: standard: 0.25% FSO option: 0.1% FSO AHD-S 201 Hydrostatic Level Transmitter Nominal pressure from 0 ... 40 cmH2O up to 0 ... 200 IT1H2O Special characteristics ► diameter 39.5 mm ► permissible temperatures up to 125 °C ► high overpressure resistance ► chemical resistance ► high long-term stability Optional versions: ► diaphragm AI2O3 99.9 % ► different housing materials (stainless steel, CuNiFe) ► IS-version zone 0 ► screw-in and flange version ► accessories e. g. assembling and probe flange, mounting clamp The hydrostatic probe LMK 458 has been devel-oped for measuring level in service and storage tanks and is as a consequence of the certification by Germanischer Lloyd predestined for shipbuilding and offshore applications. A permissible operating temperature of up to 125°C and the possibility to use the device in intrinsic safe areas enable to measure the pressure of various fluids under extreme conditions. The basis for the AHD-S 201 is a self-developed capacitive ceramic sensor element, which offers a high overload resistance and medium compatibility. Preferred areas of use are Shipbuilding / Offshore ► ballast tanks ► monitoring of a ship's position and draught ► level measurement in ballast and storage tanks Water ► drinking water abstraction ► desalinization plant ll Bonmc Automationstechnologie
