surfaces or painted, coated or anodized metals with temperature ranges between -32 and 900°C.
IN 5/5: The IN 5/5 is a stationary pyrometer especially for non-contact temperature measurement of glass
surfaces and quartz surfaces with temperature ranges between 100 and 2500°C.
For optimal match of the instrument to the application the pyrometers are equipped ex works with the desired
optics (for every instrument 3 different optics are available).
3.2 Scope of delivery
Instrument with selectable optics, allen key 2.5 mm, works certificate, user manual.
Note: A connection cable is not included with the instrument and has to be ordered
separately (see section 13,Reference numbers).
4Safety
Each person working with the pyrometer must have read and understood the user manual before operation.
Also this has to be done if the person already used similar instruments or was already trained by the manu-
facturer.
The pyrometer has only to be used for the purpose described in the manual. It is recommended to use only
accessories offered by the manufacturer.
4.1 Electrical connection
Follow common safety regulations for mains voltage (230 or 115 V AC) connecting additional devices operat-
ing with this mains voltage (e.g. transformers). Touching mains voltage can be mortal. A non expert connec-
tion and mounting can cause serious health or material damages.
Only qualified specialists are allowed to connect such devices to the mains voltage.

5Electrical installation
The pyrometers are powered by 24 V DC nominal (possible range: 10 ... 30 V). When connecting the device
to the power supply ensure correct polarity. The power consumption (in this case 4 - 20 mA) is also the
measuring signal. The instrument don’t need any time for starting or preheating and is immediately ready for
operation.
To switch off the instrument, interrupt the power supply or unplug the electrical connector.
To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used. The shield of
the connecting cable has to be connected only on the pyrometer’s side. On side of the power supply (switch
board) the shield must be open to avoid ground loops.
IMPAC offers connecting cables, they are not part of standard scope of delivery (see section 13,Reference
numbers).

7Optics
The pyrometers are equipped ex works with one of the following optics. These lenses are focusing to certain
distances. In these distances each lens achieves its smallest spot size. The spot size will enlarge in any
other distance (shorter or longer). Please notice that the measuring object must be as least as big as the
spot size.
The name of the optics (e.g. optics 300) shows the measuring distance in mm (e.g. 300 mm, measured from
the front of the lens) in which it has the smallest spot size (e.g. 6 mm).
The following drawings show the size of the spots in mm in dependence of the measuring distance. Values
between the mentioned data can be calculated by interpolation. The spot size for measuring distance 0 is the
aperture diameter Dof the optics.

8Alignment of the instrument
For exact measurement of the object temperature the pyrometer must be aligned correctly onto the object.
The instruments are not equipped with a sighting so that the aligning must be done thermally. When measur-
ing a hot object in front of a cooler background, it usually suffices to align the pyrometer to achieve the
highest temperature reading.
9Instrument settings
The emissivity of the measuring object and the and instrument’s exposure time can be set via controls in the
pyrometer housing.
The controls can be accessed by
removing the rear panel in the follow-
ing way:
1. Disconnect the electrical
connection
2. Unscrew the rear screws with a
2.5 mm allen screw
3. Take the cover off, making sure it
remains straight (without bending
or twisting it).
Assembling:
When reassembling the cover, insert it carefully into the guide pins and then fasten it with the screws. The
connector cable can now be plugged in.
9.1.1 Emissivity (EMI)
For a correct measurement it is necessary to adjust the emissivity. This emissivity is the
relationship between the emission of an real object and the emission of a black body
radiation source (this is an object which absorbs all incoming rays and has an emissivity
of 100%) at the same temperature. Different materials have different emissivities ranging
between 0% and 100% (settings at the pyrometer between 20 and 100%). Additionally the emissivity is
depending on the surface condition of the material, the spectral range of the pyrometer and the measuring
temperature. The emissivity setting of the pyrometer has to be adjusted accordingly. Typical emissivity
values of various common materials for the two spectral ranges of the instruments are listed below. The
tolerance of the emissivity values for each material is mainly dependent on the surface conditions. Rough
surfaces have higher emissivities.
Note: The minimum emissivity setting for the pyrometer is 20%!
The settings will be done via the rotary switch.
Setting examples:
EMI =100%: EMI = 85%:
Note: If the emissivity is set to an incorrect value (below 20%) the instrument will
automatically utilize an emissivity value of 100%. The setting 00 is interpreted as
EMI = 100%.

Water 95% Aluminium (anodized) 90%
Measuring object EMI (at 5.14 µm)
Glass / quartz glass 97%
One way to determine an accurate emissivity value for a material is to make a comparison measurement as
follows: If possible, coat a portion of the object with dull black paint or carbon soot. Paint and carbon soot
have high emissivities (95%) and take on the same temperature as the object. Measure the temperature of
the painted area with the emissivity control set to 95%. Then measure the temperature of an adjacent un-
painted area of the object and adjust the emissivity until the pyrometer displays the same temperature.
9.1.2 Exposure time t90
The exposure time t90 is the time interval from the start of measurement up to the respective change in the
output signal (4 ... 20 mA) which is the time taken to reach 90% of the recorded temperature difference.
The exposure time is changed by adjusting the jumper position. In the open position shown in the diagram
on the left, the response time is 0.08 s.
For alternative settings (t90 = 0.5 s, 1 s, 2 s or 5 s) select the respective jumper position (see diagram on the
right).
Longer exposure times are useful when measuring objects with fluctuating temperatures.

9.3 Avoiding reading errors caused by faulty assembly
To avoid reading errors, please note the following points when mounting the pyrometer:
1. The diameter of the measuring object cannot be smaller than the pyrometer’s spot size (see section 7,
Optics).
2. A source of radiation behind or around the measuring object can influence the result. If the object is
transparent or partly transparent another material behind the object could transmit its radiation to the py-
rometer as well. In this case the location of the pyrometer should be changed, or, if the background ra-
diation remains constant it can be compensated for by changing the emissivity setting respectively.
3. Please take into account that radiation, from other hot materials around the measured object, can be
reflected by these materials and influence the result. If the measured object has a low emissivity, the
temperature measured will be mainly that from the reflected object - not from the intended measured ob-
ject itself. To prevent ambient radiation from reaching the spot area, a mounting tube should be used.
The mounting tube should be placed as near as possible to the measured object so that the tube’s
shadow blocks out all the ambient radiation from the side.
10 Transport, packaging, storage
With faulty shipping the instrument can be damaged or destroyed. To transport or store the instrument,
please use the original box or a box padded with sufficient shock-absorbing material. For storage in humid
areas or shipment overseas, the device should be placed in welded foil (ideally along with silica gel) to
protect it from humidity.
The pyrometer is designed for a storage temperature of -20 … 70°C with non-condensing conditions. A
storing out of these conditions can damage or malfunction the pyrometer.
11 Maintenance
11.1 Safety
Attention during pyrometer services:
Should the pyrometer be integrated in a running machine process the machine has to be switched off and
secured against restart before servicing the pyrometer.
11.2 Service
The pyrometer does not have any parts which require regular service, only the lens has to be kept clean.
The lens can be cleaned with a soft cloth in combination with alcohol (do not use acid solutions or dilution).
Also standard cloths for cleaning glasses or photo objectives can be used.
The Germanium lens of the IN 5 has an anti-reflective coating which appears slightly colored. Be extremely
careful - this layer can easily be rubbed off - this will greatly affect the measuring results!

12 Trouble shooting
Before sending the pyrometer for repair, try to find the error and to solve the problem with the help of the
following list.
Temperature indication too low
•Incorrect alignment of the pyrometer to the object
⇒New correct alignment to achieve the max. temperature signal (see 8)
•Measuring object smaller than spot size
⇒check measuring distance, smallest spot size is at nominal measuring distance (see 7)
•Emissivity set too high
⇒Set lower correct emissivity corresponding to the material (see 9.1.1)
•Lens contaminated
⇒Clean lens carefully (see 11.2)
Temperature indication too high
•Emissivity set too low
⇒Set lower correct emissivity corresponding to the material (see 9.1.1)
•The measurement is influenced by reflections of hot machine parts
⇒Use mechanical construction to avoid the influence of the interfering radiation
Measuring errors
•Indicated temperature is decreasing during the use of the pyrometer, contamination of the lens
⇒Clean lens. Recommendation: use of air purge (see 11.2, 6.1)
•Indicated temperature is decreasing during the use of the pyrometer, although the air purge unit is used.
Probably compressed air is not clean or air failed
⇒Clean the lens and use clean, dry and oil free compressed air
•Air contamination in the sighting path between pyrometer and object
⇒Change position of the pyrometer with a clean sighting path (if necessary use a ratio pyrometer)
•HF-interferences
⇒Correct the connection of the cable shield (see 5)
•Instrument overheated
⇒Use cooling jacket with air or water cooling (see 6.1)
•Temperature Indication is fluctuating, probably caused by changing emissivity
⇒Wrong pyrometer type, use of ratio pyrometer recommended
