3 Safety
This chapter outlines all important safety aspects to be considered for
optimum employee protection and to ensure safe and reliable operations.
3.1 Intended use
The pyrometer is solely intended for non-contact measurement of tem-
peratures as described in this manual. Any other use is not intended.
Operational safety can only be ensured when the instrument is used for
its intended purpose.
CAUTION !
It is prohibited to use the pyrometer for any other purpose beyond what
is specified in this manual. Using the instrument in any other manner will
be considered as improper.
The Manufacturer/Authorised Agent shall not be held liable for any dam-
ages or loss resulting from such unintended or improper use; in this case
the risk is solely borne by the user.

3.2 User’s responsibility
The pyrometer may only be used when it is in perfect working condition.
3.3 Safety requirements
The instrument works with an operating voltage of 24 VDC. The voltage re-
quired for operation must be supplied by a separate power supply. This
power supply unit must conform to directive DIN IEC 61010.
3.4 Electromagnetic Compatibility
The devices comply with the essential safety requirements of the Elec-
tromagnetic Compatibility Directive 2014/30/EU (EMC Act).
When connecting a power supply unit, make sure that is also conforms
to these standards. Radio interference may arise if the pyrometer is in-
terconnected with such peripheral devices which have not been properly
interference-suppressed. This may necessitate additional interference
suppression measures.
4 General Description
The ARDOCELL PA Series provides efficient, microprocessor-controlled
pyrometers for non-contact temperature measurements
The field of applications for PA 1x includes temperature detection of ma-
terials such as synthetic materials, rubber, textiles, paper, coated sheet
steel, wood or varnish within a range from 0 °C to 1000 °C.
The ARDOCELL PA 13 is specially designed to detect the temperature
of objects in flame-heated furnaces. Because PA 13 works at a narrow
spectral range of 3.9 μm, water vapour and CO2in the detector’s field of
view will not influence the measurement, even at greater target distanc-
es. The spectral sensitivity of this model enables highly accurate and re-
liable measurements through flames and combustion gases. This py-
rometer can also tackle other atmospheric challenges such as reducing
the effect of background radiation within.
The ARDOCELL PA 15 was specially developed for temperature meas-
urements of glass. Glass is transparent in the visible spectral range and
in the near infrared range. Its emissivity depends on the wavelength, the
type and the thickness of the glass. In the range of 4.5 - 8 µm glass has
an emissivity of almost 100%. Above 5 µm, atmospheric influences, such
as humidity or water vapour, affect the measurement. The ARDOCELL
PA 15 is provided with a blocking filter with a spectral sensitivity of 4.46 -

4.82 µm. thus measuring the temperature from the near surface area of
the glass. Changes in thickness, different types of glass, or varying mois-
ture contents in the atmosphere do not affect the measurement reading
owing to the wavelength used
The ARDOCELL PA 28 and PA 29 were designed with a special band-
stop filter and sensor which ignore interfering IR radiation from sources
such as daylight or laser beams. ARDOCELL PA 28 and PA 29 features
a response spectrum which is far less sensitive to incidental light reflec-
tions from nearby hot objects than most commonly available pyrometers
which are responsive at short wavelengths.
The spectral pyrometers ARDOCELL PA 2x and PA 3x are used for
temperature measurements from 250 °C to 2000 °C or 500 °C to 2500
°C, respectively. Their applications cover large segments of the iron and
steel
producing industry and the metal, glass, ceramics and chemical indus-
tries.
To indicate the exact measurement spot, PA pyrometers features
through-the-lens sighting or, as an alternative, laser sighting or integrat-
ed camera.
The instruments have rugged stainless steel housings which make them
ideal for use in hostile industrial environments. PA pyrometers are splash
water proof according to IP65 (DIN 40050)
All PA pyrometers with through-the-lens sighting feature an interchange-
able, focusable lens. Through-the-lens sighting with target marker facili-
tates easy alignment to the target. PA instruments with laser sighting fea-
ture an integrated laser which produces a laser dot image on the target
object to indicate the precise measurement spot.
PA 1x features dynamic signal filtering known as a “smoothing function”.
This provides a steady signal and allows the pyrometer to respond quick-
ly when the temperature of the targeted surface fluctuates erratically.
The adjustable emissivity factor makes it easy to adapt the pyrometer to
the specific radiation characteristics of the particular material measured.
All pyrometers of the PA series have two analogue current outputs, each
is switchable from 0 - 20 mA to 4 - 20 mA.
The output currents are linear to the measured temperature. The re-
quired temperature range can be set at the pyrometer.

s
Operating manual PA

When ambient temperatures are higher than the admissible working
temperature, the output current is > 20.5 mA.
PA also features an analogue voltage input which can be used as an al-
ternative to current output 2. The emissivity factor or a correction for re-
flected ambient temperature can be controlled using this voltage input.
Two serial interfaces (USB and RS485) are available. They enable the
user to change all operating parameters such as emissivity setting, tem-
perature range, smoothing function or output current range during run-
ning operations.
PA pyrometers allows for continuous temperature data output in a user-
configured cycle time.
4.1 Operating Controls and Display
The rear panel of the PA pyrometer has a 4-digit display and 3 push-
buttons. The display shows the current temperature or, during configura-
tion using the push-buttons, the display will show the corresponding pa-
rameter.
Whenever the display shows a parameter, the F1 Parameter LED (yel-
low) will light up. The function of the F2 Status LED (green) is user-
configurable. In its initial state when supplied to the customer the F2 LED
indicates current status for the switch able output Do1 as ready for oper-
ation.

5.1 PA Connector Pin Assignment
CAUTION!
The pyrometer housing is connected to the signal ground via a
0.1  F/50V capacitor. Isolate any unused wires in order to avoid
the display of erroneous data.
Power Requirement 24 V DC
The instrument works with an operating voltage of 24 V DC. The voltage
required for operation must be supplied by a separate power supply. This
power supply unit must conform to directive DIN IEC 61010.
The supply voltage is 135 mA for standard design, 150 mA for models
with laser sighting and 175 mA with camera. PA pyrometer is equipped
with inverse polarity protection. The output currents and voltages share
one ground connection via pin 8 of the connector.

A self-test is performed when the instrument is switched on. The display
will briefly indicate the software version and after that the emissivity set-
ting. When the self-test is completed the pyrometer is ready for operation
and the display will show the current temperature reading.
NOTE !
In order to achieve a high degree of measurement accuracy and
repeatability it is important to allow the pyrometer time to warm
up. Turn the power supply on about 10 minutes before starting
(Camera version 20 min). We recommend that you protect the
feed line to the pyrometer against short circuit by using a 250 mA
micro fuse.
5.2 Current Outputs 0/4 - 20mA
PA pyrometer features two current outputs. Both of these outputs are ac-
tive current sources which supply linear output current. The user can se-
lect between two scales: either 0 - 20 mA or 4 - 20 mA. Maximum load is
500

.
The two current outputs are factory preset to 4 - 20 mA !
For all pyrometers of the PA series the current outputs are short-circuit-
proof and share one ground connection via pin 8 of the connector. Each
current output can be individually scaled and can be set either at the dis-
play or via interface.

5.3 Switching output
All pyrometers of the PA Series feature two switching outputs which can
be configured as digital outputs or digital inputs. The open collector out-
puts allow for a voltage of +24 V DC. The maximum current of each open
collector output is 30 mA.
See Chapter 7.2 for more information configuration.
6 Getting Started
6.1 General installation tips
Install the pyrometer in a location where it will not be unnecessarily ex-
posed to smoke, ambient heat or water vapour.
A false reading (too low) will be displayed when the pyrometer lens is
dirty. Therefore always ensure that the lens is clean.
