MAS2600: Ordering Information Reference Manual December 2014 Ed 21 Type MAS2600 -XXX-XX-X/XX Type 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.
Reference Manual MAS2600: Ordering Information Ed 21 December 2014 Measuring Ranges MAS2600 -XXX-XX-X/XX Gauge Transmitter The MAS2600 Gauge Transmitter is supplied in 4 ranges. In the programmable amplifier the measuring range is divided into 8 sub-ranges and operated by means of the range select switch. The transmitter output signal can be adjusted to 20 mA within the sub-ranges as of the table below. Range no. Transducer Type Type 1: 0 - 3.5 mH2O Type 2: 0 - 7.0 mH2O Type 3: 0 - 16.
MAS2600: Ordering Information Reference Manual December 2014 Ed 21 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 the height of the fluid from the transducer diaphragm to the surface of the fluid, including the fluid in the vent pipe.
Reference Manual MAS2600: Ordering Information Ed 21 December 2014 Forepeak Tank If transducer measuring range > tank height: Select the next measuring range. Example: Tank height 12 m. Based on the tank height a transducer with a measuring range of 16 mH2O should be selected. However, due to the dynamic conditions in the forepeak tank, a transducer with a measuring range of 35 mH2O, i.e. the next in line, should be selected. Turn amplifier range select switch to range No. 6. Draft Vent pipe min.
MAS2600: Ordering Information December 2014 Reference Manual Ed 21 Temperature Sensor MAS2600 -XXX-XX-X/XX The transducer can be supplied with a built-in Pt100 temperature sensor. The temperature sensor will only give a proper reading, if the transducer is an internally mounted type. Temperature Sensor 0 Without temperature sensor. 1 With temperature sensor.
