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 version.
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 60079-
0:2007 and IEC 60079-11:2006.
