DP500
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 100 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 400/4 0
Temperature sensors Pt 100, 4.. 0 mA
Further dew point sensors
Effective power meters
Optional third-party sensors with the following signals:
0...1/10 V, 0/4... 0 mA, Pt100, Pt1000, pulse
Application ranges:
Compressed air: Examination of refrigeration,
membrane, adsorption driers
Technical gases: Residual moisture measurement
in gases like N , O and so on
Plastics industry: Examination of
granulate driers
Medical compressed air/breathing air

4Installation and measurements
We recommend the use of a measuring chamber!
4.1 Measurement with measuring chamber, connection via plug nipple
4. Measurement without measuring chamber, connection via external thread G1/2’’
8
1. Preparation of the measuring point
Let compressed air flow 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.
. Switch on DP 500 and wait until the initialization has been
finished.
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 15 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.
1. 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.
. Screw the DP 500 (without mounted measuring chamber)
into the measuring point (with internal thread G1/ “). For
mounting you should use the spanner flat (SW 7)!
3. Switch on DP 500 and wait until the initialization has been
finished.
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 510has
stabilized. Depending on the position of the measuring point
this may take up to 15 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 flat (SW 7)!
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 certificate.
7Cable cross section
7.1 Sensor circuit points/Output signal:
AWG16 – AWG 8, cable cross-sections: 0,14 - 1,5 mm
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 1- 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 flow 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 define the reference pressure and the system
pressure.
