SMART DIFFERENTIAL PRESSURE TRANSMITTER WITH TWO DIAPHRAGM SEALS - APR-2200ALW OR APRE - 2200

Features:

• 4...20 mA output signal + HART protocol

• Accuracy 0,1%

• Intrinsic safety certificate (ATEX, IECEx)

• Explosion proof certificate (ATEX, IECEx)

• Fully welded sensor guarantees tightness of oil system for many years

• Ability to configure measuring range locally

Application and construction

The differential pressure transmitter is applicable to the measurement of pressure differences of: gases, vapors and liquids in cases where it is necessary to use seals and the pressure pulse source points may be several metres apart. Typical applications include the hydrostatic measurement of: levels in closed tanks, densities and phase boundaries, and the measurement of a filter loss, pressure differences between media in pasteurizers etc. The available range of the diaphragm seals allows measurement at great majority of media. The active element is a piezo resistant silicon sensor separated from the medium by a distance sealing system. The special design of the measuring unit means that it can withstand pressure surges and overloads of up to 40 bar. The electronic circuits are enclosed in a casing with a degree of protection IP 65 or IP66.

Configuration

The settings of the following metrological parameters can be changed:

• the units of pressure in which the range is configured,

• start and end points of the range, time constant,

• inverted characteristic (output signal 20 ÷ 4 mA).

Communication

The transmitter is configured and calibrated using a KAP-03 communicator, some other communicators (HART) or a PC using an HART/USB converter and Aplisens RAPORT 2 configuration software.

The data interchange with the transmitter enables the users the transmitter identification, as well as reading of the currently measured differential pressure value, output current and percent of range width.
