Description and Operation
MAS2600 Tank Contents Transmitter
The MAS2600 is a 2-wire 4-20 mA level
transmitter consisting of a transducer and an
amplifier interconnected by a 6-core vented
cable.
Transducer:
The transducer is a pressure sensitive silicon
micro strain gauge sensor mounted in a glass
to metal seal. The sensor is protected by an
isolation diaphragm, electron beam welded
to the transducer housing, with an oil filling
between the sensor and the diaphragm.
Pressure changes on the front of the
diaphragm will bring a resistance change in
the Wheatstone bridge of the transducer.
This change in the Wheatstone bridge will
be transmitted to the amplifier as a change in
the electrical signal.
The transducer is fully welded, housed in
titanium with a titanium diaphragm.
All transducer types are submersible (IP68).
The transducer is available in three versions:
• Gauge version.
• Absolute version.
• High temperature gauge vers io n.
As optional the transducer is available with a
built-in Pt100 temperature sensor.
Amplifier:
The amplifier is available in the following
options:
• Programmable version: Calibration is
made by dip switches and potentiometers.
• Differential version: For measuring of
both pressure and vacuum measuring.
The amplifier is housed in a sea water
resistant polyester casing (IP56).
Application
The MAS2600 has been developed for level
measuring in ballast, oil, service and fresh
water tanks as well as tanks containing
media which are not hostile to titanium.
Intrinsically Safe in Hazardous Areas
The MAS2600 is DEMKO approved for use
with standard transmitter zener barriers or
Ex isolation amplifiers and is Ex ia IIC T4
compliant in accordance with IEC 600790:2007 and IEC 60079-11:2006.
Type Approvals
DNV, GL, LRS, MRS, BV, RINA, KRS,
ABS.
CE marked in accordance with EU directive.

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
diaphragm to compensate for the atmospheric pressure. The breather pipe is connected to a
vent plug in the amplifier box. The gauge transducer is suitable for most applications.
H: High Temperature Transducer. The high temperature transducer is available in gauge version
only. The transducer is mounted with a special high temperature cable and designed for
heated tanks e.g. HFO tanks, and other applications with high tank media temperatures. The
transducer can be flange mounted or internally mounted.
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 following sub-ranges.

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 the height of the fluid (water gauge) from the transducer diaphragm to
the surface of the fluid, including the fluid in the vent pipe.
To ensure measuring accuracy a transducer type within the range no. 4, 5, 6, 7 and 8 is
recommended.
Guidelines for selection of transducer measuring ranges are set out in the following.
Selecting the Transducer Type:
Gauge and High Temperature Gauge Transducers:
The Gauge Transmitter is normally used on dry and pressure neutral locations.
The Gauge Transmitter is available in 4 ranges:
0-3.5 mH2O.
0-7.0 mH2O.
0-16.0 mH2O.
0-35.0 mH2O.

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 mH2O. In practice this means 10
mH2O less than the nominal range because of the atmospheric pressure which must be taken into
consideration when choosing the transducer.
A transducer with an effective range larger than the tank height should be selected.
:
Basic Rules:
1. The selected measuring range must be larger than the tank height.
2. The selected measuring range must be larger than
EXAMPLE: Tank height = 6 m
Vent pipe height = 14 m
1. The selected measuring range must be larger than 6 m due to the height of the tank.
2. The selected measuring range must be larger than
= 10 m due to the total height of the
tank and the vent pipe combined.
Select a transducer with a measuring range of 16 mH2O as this is the next measuring range larger
than 10 m.
Turn the range select switch on the amplifier to range No. 7.
Normally the selection of transducer, range select and calibration are done by DAMCOS.
Special consideration applies to e.g. forepeak tanks and draft measuring when selecting the
measuring range of the transducer.
Forepeak Tank:
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.

June 2013 Ed 19UK
Draft
Transducer measuring range > max. draft minus sensor position.
This rule applies provided the transducer is mounted in accordance with the installation drawing
for draft transmitters (vent pipe min. 1"). The sensor may be mounted direct on the sea valve with
an air release valve if the ship is sailing in calm waters.
If the transducer is installed in tanks which may have excessive dynamic stresses such as e.g.
high pump pressure, long bottomed tanks with a risk of slashing etc., contact Emerson Process
Management Marine Solutions, Damcos.
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.
0: Without temperature sensor.
1: With temperature sensor
Cable MAS2600-XXX-XX-X/XX
Two types of transducer cable is available. The standard cable for applications with temperatures
never exceeding 80°C, and high temperature cable for applications with temperatures up to
125°C. The transducer cable is delivered in whole meters.
For further information require data sheet.
To make the MAS2600 transmitter easy to install, and for later service purposes, the transducer
cable should be as short as possible, though considering the position of the transducer and
amplifier box.
Max. cable length: 300 m.
When installing in hazardous areas max. cable length: 75 m.
