SMART DIFFERENTIAL PRESSURE TRANSMITTER FOR LOW RANGES - APR-2000GALW

Features:

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

• Display with backlightProgrammable range, zero shift, damping ratio and characteristic with local panel keys

• Selectable linear or radical conversion characteristic

• Accuracy from 0,1%

• Intrinsic safety certificate (ATEX, IECEx)

Application

The APR-2000GALW transmitter is applicable to the measurement of differential pressure of gases. Typical applications include the measurement of blast pressure, chimney draughts 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 overpressure up to 1 bar. The housing of the electronic circuit has the degree of protection IP66/IP67.

Communication

Communication with the transmitter is carried out with a KAP-03 communicator, some other Hart communicators or a PC with an Hart/USB converter and RAPORT 2 configuration software.

Additionally, the data interchange with the transmitter enables the users to identify the transmitter, read the currently measured pressure difference value, output current and percentage of measuring range.

Configuration, calibration

The following metrological parameters can be configured:

• The units of pressure,

• Start and end-points of measuring range, damping time constant,

• Conversion characteristic (radical, inversion, user’s nonlinear characteristic).

Ability to calibrate the transmitter with reference to a standard pressure.
