NOTES ON SAFETY

DESCRIPTION

The FA 410 dew point sensor enables a reliable and long-term stable monitoring of the dew
point in industrial applications from -80 to +20 °C dew point. The FA 410 features improved
stability.

When mounting FA 410 into compressed air systems the pressure dew point (dew point
under pressure) up to 50 bar (in the special version up to 350 bar) is measured directly.
When mounting FA 410 in atmospheric conditions (ambient pressure) or in the flow off sector
(relaxed air) of compressed air systems the atmospheric dew point is measured.

Advantages:

 Dew point sensor for very low dew points down to -80 °Ctd
 Extremely long-term stable due to internal automatic calibration
 IP 65 housing grants a reliable protection in extreme industrial conditions
 Very fast response time
 Installable in the dryer by means of G 1/2" thread
 High accuracy of  2 °Ctd
 Calibration on location and testing with CS control and calibration set (PC connection set)

Programming via SFA Software.

- Analogue output 4…20 mA scalable

- Calibration and adjustment including issuing of certificates

- Switching between °Ctd, % RH, g/m³ and so on

- Read-out of service data

Please read prior to operation!
Warning: Do not exceed a pressure range of > 50 bar with standard version. With special

versions up to 350 bar.
Observe measuring ranges of sensor! The probes are damaged if they are overheated.
Observe max. storage and transport temperature as well as max. operating temperature

(e. g. protect measuring instrument from direct sunlight).
Warranty claims no longer apply if the instrument is opened, in the case of inexpert handling

or use of force.
Adjustments or calibrations should be carried out by qualified measurement and control

engineering staff only.
Important: Before installation briefly bleed the compressed air in order to remove condensate

and particles. This prevents soiling of FA 410. Standing air leads to long measuring times.

INSTALLATION

Please note: CS recommends the indirect installation with measuring chamber

Advantage: Easy mounting and dismounting
of the probe without interruption of

the line. Quick response time due
to quick coupling. Optimum sensor
protection.

Indirectly in the compressed air system

Connect probe with measuring chamber to the
compessed air pipe by means of a quick
coupling. In case of compressed air containing
oil and dirt particles a pre-filter should be
installed in front of the measuring chamber.
Compressed air flows continuously (at 7 bar
approx. 1 l/min expanded) in the capillary pipe of
the measuring chamber. The reaction times for
the humidity reading are shorter than in case of
a direct mounting.

Directly in the compressed air system

Screw in probe with G 1/2" thread pressure-tight
in the center or at the top of the compressed air
pipe. Take care that measurement is effected
close to the compressed air flow. U-bend pipes
or non-flowing compressed air result in very
slow reaction times for the moisture reading.

Measurable gases

In general, humidity can be measured in all non­corrosive gases. In case of measurements in
corrosive gases please consult CS Instruments
GmbH.

CALIBRATION/ADJUSTMENT

From the manufacturer
According to DIN ISO certification of the measuring instruments we recommend regular
calibration and, if necessary, adjustment of the instrument by the manufacturer. The
calibration cycles should fit your internal scheme. In the course of the DIN ISO certification
we recommend for FA 410 a calibration cycle of one year. If requested we can carry out the
calibration on your premises.

WARRANTY

If you have reason for complaint we will of course repair any faults free of charge if it can be
proven that they are manufacturing faults. The fault should be reported immediately after it
has been found and within the warranty time guaranteed by us. Excluded from this warranty
is damage caused by improper use and non-adherence to the instruction manual.

The warranty is also cancelled once the measuring instrument has been opened provided
this is not described in the instruction manual for maintenance purposes. This is also the
case if the serial number has been changed, damaged or removed.

The warranty time for FA 410 is 12 months for the instrument and 6 months for accessories if
no other terms are agreed upon. Warranty services do not extend the warranty time.

If in addition to the warranty service necessary repairs, adjustments or similar are carried out,
the warranty services are free of charge but there is a charge for other services such as
transport and packing costs. Other claims, especially those for damage occurring outside the
instrument are not included unless responsibility is legally binding.

After-sales service after the warranty time has elapsed
We are, of course, there for you after the warranty time has elapsed. In the case of function
faults please send us your measuring instrument with a brief description of the defect. Please
also indicate your telephone number so that we can contact you if necessary.
