SMART DIFFERENTIAL PRESSURE TRANSMITTER FOR LOW RANGES - APRE-2000G

Features:

• Programmable range, zero shift, damping ratio and characteristic

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

• Accuracy from 0.1%

• ATEX Intrinsic safety (only APRE-2000G/PD, APRE-2000G/PZ)

Application

The APRE-2000G transmitter is applicable to gases, to the measurements of their pressure, under pressure and differential pressure. 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 IP65, IP66 , IP67.

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 non-linear characteristic).

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

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.
