AED28 Differential Pressure Transmitter

Features: — differential pressure 0 ... 6 mbar up to 0 ... 1.000 mbar — accuracy: 1 % FSO — piezoresistive pressure sensor

The differential pressure transmitters of the PRD-33X series are designed for accurate measurements in low pressure ranges with very high overload on both sides. In addition to the differential pressure sensor, which may only be exposed to gases at its rear face, the devices have an additional absolute pressure sensor that measures the line pressure. Both measured values are output via the digital RS485 interface and are the ideal basis for cryogenic tank monitoring.

The pressure transmitter illustrated here measures differences in pressure between the two connections of the measuring element. Pressure differences can be measured with respect to a reference pressure, such as atmosphere, or to the command variable of a regulation system. Equally, however, it is possible to measure pressure differences within systems that have a high static pressure. One practical example of this would be measuring a flow rate by determining the pressure drop occurring across a metering diaphragm. The differential pressure transmitter measures in both directions and can therefore, for instance, be used on double-acting hydraulic cylinders. Its construction permits it to be used with liquid or gaseous media. Venting holes simplify installation. The robust design and the use of stainless steel make it possible to use the pressure transmitter under tough operating conditions.

Isobaric Monoblocs for bottling carbonated liquids such as mineral water, soft drinks, beer, and sparkling wines. Comprising a rinsing turret (optional), a high-pressure filling turret, and a capping head for each closure type. The rotary filling groups are available starting from 6 valves and can be configured in various versions. The machine consists of a base with adjustable supports, welded to a rigid structure to reduce vibrations. On the base, you'll find the central support for the filler, the motorization, and gears that control the movements of both the screw conveyor and the bottle inlet/outlet stars. The isobaric tank is fixed to the cylinder-carrying flange via the tank height adjustment device. The specific filling valves are fixed to the isobaric tank. Equipped with a control panel featuring low-voltage buttons and thermal relays. Production: from 1,000 to 15,000 bottles per hour.
