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 Wheat-stone 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 versionAs optional the transducer is available with a built-in Pt100 temperature sensor.
