Installation & User Manual Ed 19UK June 2013 Type MAS2600-XXX-XX-X/XX A: Absolute Transducer. The absolute transducer has no breather pipe, because it refers to absolute vacuum. An atmospheric pressure sensor is used to compensate for the atmospheric pressure. The absolute transducer is especially suitable for open deck applications, where the amplifier box may be exposed to flooding. G: Gauge Transducer. The gauge transducer is fitted with a breather pipe at the back of the di

Installation & User Manual June 2013 Ed 19UK Absolute Transmitter: The MAS2600 Absolute Transmitter is available in two ranges. The output signals are calibrated as follows: Transducer type 4 : 0.8 - 3.5 bar abs Transducer type 7 : 0.8 - 2.0 bar abs Selecting the Measuring Range: When selecting the measuring range it is important to consider the tank height, vent pipe height, the tank type and the specific gravity (SG) of the tank contents. The transducer measures

Installation & User Manual Ed 19UK June 2013 Absolute Transducers: The Absolute Transmitter is typically used if the amplifier is exposed to water, e.g. on open deck. The Absolute Transmitter is available in 2 ranges: 0-20 and 0-35 mH O. In practice this means 10 2 mH O less than the nominal range because of the atmospheric pressure which must be taken into 2 consideration when choosing the transducer. A transducer with an effective range larger than the tank height should

Installation & User Manual Ed 19UK June 2013 If the amplifier box is installed in an area with over pressure or negative pressure in relation to the atmospheric pressure in the tank, the breather tube must be directed to an area with atmospheric pressure equalling the pressure inside the tank. This applies to gauge transmitters only. For absolute transmitters this has no affect, due to the reference to absolute vacuum and not atmospheric pressure. This is also the reason why no breath
