Anderson Negele Differential Pressure & Level Transmitter D3

Anderson Negele Level Transmitter

Features:-

• It uses the proven state-of-the-art temperature compensation technology of L3 and significantly reduces the effects of process and ambient temperature changes.
• The graphical user interface with intuitive menu structure makes field setup and programming very easy.
• Second mA output can be used for independent monitoring of inlet/outlet pressure in filter application or top (head) / bottom (system) pressure in level applications using single transmitter head.
• The diff mA output can be scaled to volumetric units like gallons and lbs.
• Display can be direct mounted to either of the two sensors or can be mounted remotely for easy access.

     ♦ Range of applications:-

• Head pressure and level measurement in pressurized vessels with continuous process temperature up to 110°C (230°F).
• Differential pressure measurement across filters.
• CIP/SIP at 135°C (275°F) for 1 hour when ambient is below 60°C (140°F).

     ♦  Hygienic design/Process connection:-

• Front flush, 3-A installation for silos by Anderson flush fitting, E&H universal, or tank spud connections.
• Conforming to 3-A Sanitary Standard 74-06 with Tri-Clamp® DIRECTadapt.
• Product contacting materials compliant to FDA.
• Sensor and product contact surfaces made of stainless steel.
• Available with over 20 integral hygienic connections, more available through CLEANadapt adapters.

     ♦ Options/Accessories:-

• Optional digital remote kit making display easier to view.
• Optional M12 molded cordset available.
• Wide range of ranges and fittings available.

Measuring principle of the pressure sensor:-
In the D3 system each sensor uses a piezoresistive transducer to measure the difference between the atmospheric and process pressures. Additionally, temperature sensor measures the temperature of the transducer and fill fluid to provide an output compensation. The resistive temperature signal and the
voltage signal from the transducer are inputs to a correction algorithm which provides a pressure output in digital form. The digital signal is transferred from
each sensor to the head where the microprocessor determines the difference and converts the output to a 4-20mA signal for the difference and one for the head pressure or total system pressure depending on the user’s selection.
