Differential pressure transmitter APR-2000ALW

membranepiezoresistive4-20 mA

The APR-2000ALW transmitter is applicable to the measurement of differential pressure of gases, vapours and liquids. The active element is a piezo-resistant 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 250/320/413/700/1000 bar. The casing is made of aluminium alloy cast, degree of protection IP6. The design of the casing enables the use of a local display, rotation of the display and rotation of the casing by 0–340° relative to the sensor, and a choice of cable direction. • 4…20 mA output signal + HART 5 / HART 7 protocol (special version: 0…20 mA or 0…5 mA output signal + HART 5 protocol) • Display with backlight • Safety version SIL2/SIL3 • Intrinsic safety certificate ATEX, IECEx, FM (USA, CANADA), INMETRO (Brazil), KCs (Korea) • Explosion proof certificate ATEX, IECEx, FM (USA, CANADA), INMETRO (Brazil), KCs (Korea) • Programmable zero range, shift, characteristic and damping ratio with local panel keys • Static pressure limit up to 1000 bar • Accuracy 0,075% (0,05%, 0,04% on request) • Marine certificate – DNV, BV • Gold plated diaphragms • Wetted parts material 316L/Hastelloy C276/Tantalum/Gold plated
