The APR-2000ALW transmitter 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 250/320/413/700 bar.The
casing is made of aluminium alloy cast or 316SS stainles steel, degree of protection IP66/IP67. The design of the casing enables the use of a
local display, rotation of the display, rotation of the casing by 0–340° relative to the sensor, and a choice of cable direction.
