Application

Our APR-2000G transmitter is designed to measure pressure,

underpressure and differential pressure of non-corrosive

gases. Typical applications include the measurement of blast

pressure, chimney draughts or pressure/underpressure 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 is built to withstand up to 35 kPa

overpressure. The housing of the electronic circuit is IP 65

rated.

Configuration, calibration

You can select the following settings of metrological parame-

ters:

♦

Pressure units for the active measurement range

♦

End-points of range, damping

♦

Radical conversion characteristics

♦

Inverted characteristics (output signal 20 ÷ 4 mA).

Ability to perform zero shift and calibration against pressure

standard.

Communication

Hart protocol with 4 ÷ 20 mA signal. Setting and calibration

through KAP-01 communicator unit, some Hart compatible

communicators or a PC through an RS-Hart interface and

Aplisens RAPORT-01 software. APR-2000G data transfer also

supports transmitter identification, as well as current readings

of pressure difference, output current and percentage of

measuring range.

Assembly

The economical version can be mounted on any stable con-

struction using the assembly fixture with

∅

9 opening. The

transmitter includes pipe stubs with terminals to connect to an

elastic

∅

6×1 impulse line. Where the pulse comes via a metal

pipe, we suggest the use of an M20×1.5 adapter for a

∅

6×1

fitting.
The transmitter with a C type connector should be mounted on

a 3- or 5-valve manifold. We recommend the use of our pre-as-

sembled transmitters with VM type valves (page 44).

Version II/2002

Operating guidelines

The transmitter should be mounted in a vertical position. The impulse lines should be connected in such a way as to

ensure that any condensation flows off away from the device.
Where there is a significant difference in height between the place where the transmitter is mounted and the place where

the pulse is taken, the measurement may vary with the temperature of the impulse line. This effect can be minimized by

connecting a compensating pipe close to the impulse line, from the transmitter’s reference pipe stub to the height at

which the impulse is taken.
To prevent dust from entering the measuring cells, the impulse lines should be attached with care, with particular atten-

tion to the tightness of the connections between the impulse lines and the transmitter.
