Description and Operation

MAS 2600 Tank Contents Transmitter
The MAS 2600 is a 2-wire 4-20 mA level transmitter consisting of a transducer, an amplifier
and an interconnecting 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, 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 two versions:
Gauge version
•
Absolute version
•
As optional the transducer is available with a built-in Pt100 temperature sensor.
Cable
The cable is available as a standard version and as a high temperature version.
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
•
The amplifier is housed in a sea water resistant polyester casing (IP56).
Application
The MAS 2600 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 MAS 2600 is certified for use with standard transmitter safety barriers or Ex isolation
amplifiers and is Ex ia [ia Ga] IIC T4 Gb compliant in accordance with IEC/EN 60079-0 and
IEC/EN 60079-11.
Type Approvals
DNV, GL, LRS, MRS, BV, RINA, KRS, ABS, PRS.
CE marked in accordance with EU directive.
