Smart Differential Pressure Transmitter APR-2000 ALW is applicable to the measurement of differential pressure of gases, vapours and liquids. The active element is a piezoresistant silicon sensor separated from the medium by separating diaphragms and a specially selected type of manometric fluid. The special design of the active sensing element ensures that it is able to withstand pressure surges and overloads of up to 250/320/420 bar.The casing is made of aluminium alloy cast or 316SS stainless steel, degree of protection IP 66/IP 67. The design of the casing enables the use of a local display, rotation of the display, rotation of the casing by 0–340°C relative to the sensor, and a choice of cable direction.

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

Smart Differential Pressure Transmitter APR-2000 ALW is 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.

Smart Differential Pressure Transmitter APR-2000 ALW generate a 4…20mA 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” configuration software.
