Smart Differential Pressure Transmitter APR-2000G ALW

• Digital PROFIBUS PA signal
• 4…20 mA output signal + HART protocol
• Accuracy from 0.1%
• ATEX intrinsic safety certificate
• Programmable zero range shift, characteristic and damping ratio with local panel keys
• Selectable linear or radical conversion characteristic

The smart differential pressure transmitter APR-2000G ALW is applicable to the measurement of pressure differences of: gases. Typical applications include the measurement of blast pressure, chimney droughts  or pressure/ under-pressure in furnace chambers. The ability to select the radical conversion characteristics enables the transmitter to be used in gas-flow measurement systems using reducing pipes or other impeding elements. The transmitter can withstand over-pressure up to 1 bar. The housing of the electronic circuit has the degree of protection IP 66/ IP 67.

The smart differential pressure transmitter APR-2000G ALW is designed to measure gauge pressure, vacuum pressure and absolute pressure of gases, vapors and liquids (including corrosive substances).

The smart differential pressure transmitter APR-2000G ALW is used to measure liquid levels in closed tanks, with static pressure up to 25 MPa, or 32 MPa for special versions and to measure differential pressure across constrictions such as filters and orifices.

The smart differential pressure transmitter APR-2000G ALW may be fitted with a range of types of process connectors, which enables them to be used in a variety of conditions such as thick or highly reactive media, high and low temperatures, etc.

The smart differential pressure transmitter APR-2000G ALW generate a 4…20 mA output signal and a digital communication signal in a two wire system (current loop). The use of smart electronics enables regulation of the zero point, the measurement range, damping, radical conversion characteristic and other functions using an Aplisens KAP communicator or from a PC using a Hart/RS232 converter and Aplisens “Raport-01” configuration software.
