2Application area
The new instruments DP 500 are the ideal portable service instruments for dew point measurement for all types of driers
down to -80°Ctd dew point
The 3.5” graphic display with touch screen makes the operation very easy..
The graphic indication of colored measuring curves is unique.
Ideal for measurement of the current dew point and for graphic indication of the dew point curve/the switching behavior of
the drier over a longer period of time.
Up to 00 million measured valued can be stored with date and measuring site name. The measured data can be transferred
to the computer via USB stick or USB cable.
A part from the internal dew point measurement one further optional sensor can be connected like for example:
Pressure sensors
Flow sensors, VA 400/420
Temperature sensors Pt 00, 4..20 mA
Further dew point sensors
Effective power meters
Optional third-party sensors with the following signals:
0... / 0 V, 0/4...20 mA, Pt 00, Pt 000, pulse
Application ranges:
Compressed air: Examination of refrigeration,
membrane, adsorption driers
Technical gases: Residual moisture measurement
in gases like N2, O2 and so on
Plastics industry: Examination of
granulate driers
Medical compressed air/breathing air

4Installation and measurements
e recommend the use of a measuring chamber!
4.1 Measurement with measuring chamber, connection ia plug nipple
4.2 Measurement without measuring chamber, connection ia external thread G1/2’’
8
. Preparation of the measuring point
Let compressed air ow off at the sampling point before measurement in
order to remove condensate and particles. This avoids a soiling of DP 500 and
the measuring chamber.
Stagnant air leads to long adjustment times.
If condensate occurs at the measuring point please check the compressed-air
conditioning before measurement.
2. Switch on DP 500 and wait until the initialization has been nished.
Please observe the chapter "Operation".
3. Connect the measuring chamber screwed onto DP 500 with the plug
nipple coupling of the measuring point
4. Wait until the value in the display of DP 500 has stabilized. Depending on
the position of the measuring point this may take up to 5 minutes.
5. Disconnect the measuring chamber from the plug nipple coupling of the
measuring point after measurement. Switch off DP 500 if you do not want to
carry out further measurements.
. Preparation of the measuring point
Make sure that the measuring point is depressurized.
Please check the sampling point before measurement.
If condensate occurs at the measuring point you should check the
compressed-air conditioning before measurement.
2. Screw the DP 500 (without mounted measuring chamber) into the
measuring point (with internal thread G /2“). For mounting you should use
the spanner at (SW27)!
3. Switch on DP 500 and wait until the initialization has been nished.
Please observe the chapter "Operation".
4. Charge the measuring point slowly with pressure.
5. Wait until the value in the display of DP 500 / DP 5 0has stabilized.
Depending on the position of the measuring point this may take up to 5
minutes.
6. After measurement please drain the pressure slowly from the measuring
point.
7. Remove DP 500 from the measuring point. For demounting the instrument
you should use the spanner at (SW 27)!
8. If you do not want to carry out further measurements please switch off DP
500.

4.3 Dew point measuring at synthetic granules - dries
5Maintenance
Cleaning of thesensor
The sensor can be cleaned by careful swinging in distilled water or isopropanol.
Remark:
Do not touch the surface of the sensor pad.
Avoid mechanical impact to the sensor (e. g. by means of a sponge or a brush).
If the sensor is very polluted the only possibility will be an examination and maintenance by the manufacturer.
6Calibration/ Adjustment
We recommend an annual calibration and if necessary adjustment of the measuring instrument at the manufacturer.
Please observe the enclosed inspection certicate.
7Cable cross section
7.1 Sensor circuit points/Output signal:
AWG 6 – AWG28, cable cross-sections: 0, 4 - ,5 mm2
9
Synthetic granules-dries usually work with a slight positive pressure in the
millibar range. Usein this application,witha slight excess pressure, the
measuring chamber forsynthetic granules dryer.
Since the air temperature in the synthetic granules dryer is also very high, the
air supply from the synthetic granules dryer to the measuring chamber via a
correspondingly long PFA tube (recommended length of -2 m), which serves
as a cooling section. Note that the measured air temperature in the DP 500 if
possible remains below 40 ° C, otherwise please use a longer PFA tube as a
cooling section.
The supply of airinto the measuring chamberviaport A (air input). On the air
output, a PFA tube isconnectedwith a length ofat least 80 cm. Thisprevents
theback ow ofhumidambient airbackinto the measuring chamber.

8.3.2.1.2.1 Settings internal Dewpoint-Sensor
With the DP 500 the pressure dew point in the pressure line is measured automatically. The pressure dew point is always
related to the pressure in the line.
A pressure input is not necessary, because the measuring principle measures independent of pressure.
The DP 500 is able simultaneously to the pressure dew point alsocalculate the atmospheric dew point or dew point at
reduced pressure.
For the calculation of the atmospheric dew point (if the gas would be expanded to ambient pressure) or the dew point at
reduced pressure, it is necessary to dene the reference pressure and the system pressure.
