1 GENERAL DESCRIPTION
Infrared thermometers measure the object surface temperature without touching it. They calculate the surface
temperature on the basis of the emitted infrared radiation from an object. The most important feature of
infrared thermometers is that they enable the user to measure objects contact less. Consequently, these
products help to measure the temperature of inaccessible or moving objects without difficulties.
As the infrared sensor Eurotron IRtec Rayomatic 14 consists of two pieces (miniature sensing head with
separate electronics) it can easily be installed in a variety of applications, especially if industrial environment
requires space-saving installation. The stainless steel sensing head as well as the teflon-coated cable are
standard equipment for ambient temperatures up to 180 °C. The labeling of each sensing head with the
according calibrating code allows the exchange of head or electronic box without additional calibration.
The sensor electronics of the IRtec Rayomatic 14 is placed inside a rugged die casting box. Various analogue
outputs (0/4 – 20 mA, 0 – 10 V, thermocouple type J or K) and optional digital interfaces (USB, RS232,
RS485) are available.
Easy accessible programming keys and a back-lit LCD display permit a Smart Panel-Operation to set
and adjust essential parameters on-site.
Report of Calibration
IRtec Rayomatic is delivered, on request, with a Report of Calibration, traceable to the International Standards
stating the nominal and actual values and the deviation errors.
RS232 & Software
An optional RS232 PC adapter allows the changes of the configuration parameters (emissivity, response time,
measuring span, average, peak-picker, decay, etc) and digital communication for remote PC display of
temperature. The software LogMan let the operator to monitor the temperatures in real time mode with a
graphic visualization too. The measured values can be stored and afterward re-managed on the PC for your
future needs.

Instruction manual MM850618 ed. 01e
3 PRINCIPLE OF OPERATION
Basics of Infrared Thermometry:
Depending on the temperature each object emits a certain amount of infrared radiation. A change in the
temperature of the object is accompanied by a change in the intensity of the radiation. For the measurement
of “thermal radiation” infrared thermometry uses a wave-length ranging between 1 µ and 20 µm.
The intensity of the emitted radiation depends on the material. This material contingent constant is described
with the help of the emissivity which is a known value for most materials (see enclosed table emissivity).
Infrared thermometers are optoelectronic sensors. They receive thermal radiation and transform it into
measurable electrical signals. Infrared thermometers basically consist of the following components:
lens
spectral filter
detector
electronics (amplifier/ linearization/ signal processing)
The specifications of the lens decisively determine the optical path of the infrared thermometer, which is
characterized by the ratio Distance to Spot size.
The spectral filter selects the wavelength range, which is relevant for the temperature measurement. The
detector in cooperation with the processing electronics transforms the emitted infrared radiation into electrical
signals.
Maximum Distance and Spot Size:
The size of the measuring object and the optical resolution of the infrared thermometer determine the
maximum distance between sensing head and measuring object. In order to prevent measuring errors the
object should fill out the field of view of the optics completely. Consequently, the spot should at all times have
at least the same size like the object or should be smaller than that.
Ambient Temperature:
The IRtec Rayomatic 14-high-temperature sensing heads are designed to measure temperatures while
tolerating ambient temperatures ranging between -20°C and 180 °C (25:1 head) or from -20°C to 120 °C (HS
14:1 and 2:1 heads). The cable between head and electronics is teflon coated and also usable for this ambient
temperature range. Therefore measurements in the specified range can be done without a cooling of the
sensing head.
Air Purity:
The lens must be kept clean at all times from dust, smoke, fumes and other contaminants in order to avoid
reading errors and damage to the lens. For that purpose an air purge collar is available as an accessory part.
Make sure to use oil-free, technically clean air, only.

5 INSTALLATION
IRtec Rayomatic installation is quite easy. The cylindrical stainless steel case is externally threaded and
allows quick installation of all available accessories.
The following procedure should help you during the installation procedure of your IRtec Rayomatic
thermometer.
• The emissivity is standard set to 0.95 and the temperature span is set as required in the ordering table. If
you need different values, read the configuration of the thermometer by using the configuration software
and the Smart/RS232 converter. Connect the IRtec Rayomatic 14 to the PC and set the mathematical
function, the emissivity and the temperature span.
• Connect, if necessary, all accessories such as air purge, support, sighting tube, etc. Install and align the
IRtec Rayomatic to the process.
• Connect the signal cable to the receiver (controller, indicator, etc.) paying attention to the polarity.
• Aim accurately the thermometer to your target. Refers to Target vs. distance table on the relevant section
1. Be sure that your target is well inside the measuring area.

Power supply:
Please use a power supply unit with an output voltage of 8 – 36 VDC/ 100 mA.
Cable connection:
The cable gland M12x1,5 allows the use of cables with a diameter of 3 to 5 mm.
To prevent electrical and electromagnetic faults and variance of measuring values keep to the following
precautions:
Please install the measuring head and the electronic box in a distance as far as possible from any source,
which may cause electromagnetic interference (e.g. modules with electromotor-impulse).
If necessary, mount the head insulated to prevent ground loops.
CAUTION: Use shielded cables only. The sensor shield has to be grounded.
Preparation of the cable:
Remove the isolation from the cable (40 mm power supply, 50 mm signal outputs, 60 mm functional inputs).
Cut the shield down to approximately 5 mm and spread the strands out. Extract about 4 mm of the wire
isolation and tin the wire ends.
Installation of the cable:
Place the following components one after the other onto the prepared cable end:
The cap, the clamp ring, the rubber washer and one metal washer of the cable gland. Spread the strands and
fix the shield with the second metal washer. Insert the cable into the cable gland until the limit stop. Screw the
cap tight. Every single wire may be connected to the according screw clamps according to their colors.
Sensing head/ -head cable:
The standard delivery includes the connected cable of the sensing head to the electronic box. You may
shorten but never lengthen the cable. To shorten the cable may cause additional measuring errors of about
0,1 K/ m.
The head is exchangeable.

Instruction manual MM850618 ed. 01e
Fig. 5-1: Dimensions IRtec Rayomatic 14 head and electronic box
In order to align the bracket with the target, look through the support hole (without the thermometer) and find
the best position. It's important for the optic path to be free from any obstruction (steam, dust, etc.). In
particular, when the surface is targeted through a hole, the hole diameter has to be big enough according to
the distance from the instrument. The thermometer has to be installed in an accessible place for any further
maintenance operation, and it hasn't to be exposed to excessive heat, smoke and steam.
