5 Technical Description
5.1 System Design / Principle of Operation
Figure 1 shows the basic structure of the pyrometer. The outgoing infrared radiation from the object being
measured is focused on an infrared detector through an entry optics. The detector produces an electrical signal
corresponding to the radiation which is then amplified and processed. This signal is converted into an output
value using digital signal processing which is proportional to the temperature of the object and is displayed
on the screen or is output as an analogue signal (standard signal 0 /4 . . . 20 mA) and/or digital signal. The
pyrometer is thus exceptionally suitable for integration into existing measuring and control systems.
There is also an RS485 interface available for the data output, which thus also allows external access to the
instrument parameters.
The operating elements as well as the connections/interfaces are located at the back of the pyrometer (see
Operating and display elements (section 5.3) at page 10.
The coolant connections are located under the instrument.
IMPORTANT:
The pyrometer must never be operated without the associated cooling!

5.2 Optics
Depending on the application (measuring distance, measuring field diameter, etc.), the pyrometer is equipped
with a vario-optics or a macro-optics.
5.2.1 Vario optics
The Vario-optics can be adjusted to the required measuring distance and allows very small measuring fields for
various distances to the object being measured. The object being measured can be at an arbitrary distance,
but must be at least as large as the measuring field at that distance (see. Setting the Vario optics (section 7.1)
at page 17).

Cold tap water is usually sufficient for cooling. It should not be so strongly cooled that condensation develops
on the instrument. Take into account the environmental conditions (air temperature and humidity) with respect
to the cooling.
5.6 Mounting rail
There is a mounting rail under the instrument for fixing the pyrometer through which the pyrometer can be fixed
using various brackets.
We recommend fixing the pyrometer to the mounting rail using a clamp. This mounting plate ensures secure
assembly of the pyrometer as well as optimal adjustment with respect to the object being measured (for order
data see. (section 3.3) at page 6).
5.7 Data exchange
The pyrometer has a RS485 interface. The RS485 interface allows data exchange between the pyrometer and
a central processing unit (e.g. computer) using commands (see Command list (section 12) at page 33). The
interface works in half duplex, i.e. it can either send or receive. The interface is characterized by the following
parameters:
• 8 data bits
• 1 stop bit
• Even parity
• Baud rate adjustable (see Command list (section 12) at page 33)
The transmission with the RS485 interface is as far as possible not susceptible to interference, it is used for
very long transmission distances and one interface can be linked to up to 32 pyrometers in a bus system.
Connection example of RS 485 interface
Half-duplex operation A1 and A2 as well as B1 and B2 are bridged in the 12-pole circular connector of the
cable to avoid over-long branch lines and thus reflection and to avoid interrupting the RS485 data bus when
disconnecting a plug.The transmission rate of the interface (in Baud) depends on the cable length. Values
between 1,200 Bd and 115,200 Bd can be set. A benchmark for 19,200 Bd is 2 km total cable length. The
baud rate which can be used is halved with the doubling of the transmission distance.

6.1 Installation Site Requirements
CAUTION:
Measurement errors and damage to the pyrometer through:
• Ambient temperatures too high
• Strong contamination of the optics due to dust, smoke, steam or other causes air pollution
• Electromagnetic interference sources
You must take into account the following climatic conditions and the requirements of the place of use
of the pyrometer!
6.1.1 Climatic conditions
The following requirements must be fulfilled with respect to the climatic conditions at the place of use of the
pyrometer:
• Temperature range 0 °C to +70 °C (with cooling connected)
• Maximum air humidity 60 % at room temperature
• Atmosphere free of dust, corrosive vapours, and fume gases
6.1.2 Requirements at the place of use
Take into account the following requirements at the place of use of the pyrometer:
• Take care with the choice of the place of use and take into account the ergonomic and the legal guidelines
for industrial safety in order to ensure safe operation of the pyrometer.
• Set up the pyrometer on a firm, stable base. The base must be free from concussion and vibration.
Note:
We recommend using the rail mounting plate available as an accessory for the attachment of the pyrom-
eter as well as a clamping attachment (see. Accessories (section 3.2) at page 4.
• Do not expose the system to direct sunlight or radiation from heating (e.g. radiators).
• Do not set the pyrometer near strong electromagnetic fields or near electromagnetic interference sources.
• Make sure that the pilot light falls unhindered on the object being measured and that there is nothing in
the path of the rays.
IMPORTANT:
Temperature measurement through windowpanes is not possible with this pyrometer! However, if the
measurement must be effected through protective glass, then the latter must be made of infrared-
permeable materials (e.g. CaF2) with an appropriate spectral range.

6.2 Installation
6.2.1 Fix and connect the pyrometer
DANGER:
There is danger of injury and possible equipment damage by connection of cables under power!
Never connect cables under power! Make sure that the voltage supply is switched off before connection
of the cables to the pyrometer!
IMPORTANT:
Operation of the pyrometer is only permitted with water cooling! Connect the pyrometer to a suitable
cooling circuit with ordinary tap water! The use of coolants is permitted only with the agreement of the
manufacturer!
The temperature of the cooling water must lie between 10 °C and 20 °C (optimal 18 °C). Condensation
build-up due to the low temperature of the cooling water is to be avoided. In case of failure of the
cooling, the measuring procedure must be interrupted immediately (see Troubleshooting (section 8) at
page 29.
Install the pyrometer as follows:
1. Mount the pyrometer taking into account the conditions specified in Installation Site Requirements (sec-
tion 6.1) at page 14 for the intended place of use.
2. Connect the water cooling (see Figure 9).
3. Connect the 12 pole connecting cable to the pyrometer at the back of the instrument (see Figure 9) and
to the power supply.
4. Connect, if necessary, the switching outputs (see Figure 9).
XThe pyrometer is ready for use and can be switched on.

6.2.2 Align pyrometer
The pyrometer is equipped with an LED pilot light for accurate alignment of the sensor with the object to be
measured. Align the pyrometer with the object to be measured as follows:
1. Switch on the supply voltage to the pyrometer.
2. Allow a starting time of approx. 1 minute for thermo-stabilization (dependent on the coolant temperature).
Note:
In the display, the indication of the cooling performance is given in per cent. On reaching the ready status,
the instrument switches into the measuring mode.
3. Switch on the pilot light by pressing the [OK] key. Make sure that there is nothing in the path of rays.
Note:
In order to avoid measuring errors, the area of the pilot light must not be larger than the object to be
measured.
4. If you have a pyrometer with Vario optics, adjust the necessary measuring distance (see Setting the Vario
optics (section 7.1) at page 17).
Note:
The macro-optics cannot be adjusted.
XThe pyrometer is thus aligned and ready for the temperature measurement.
