3 Controls and Connections

3.1 Electrical 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 doesn’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 Chapter 7, Reference

Numbers).

Example for wiring using a digital display with integrated power supply:

Example for wiring using an external power supply:

Note: Additional analyzing instruments, e.g. controllers, recorders, etc can be

connected in series as shown in drawing above.

3.2 Pin assignment at the pyrometer

3.3 Optics

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 D of the optics.

*Data based on the IN 5/5, MB 25.

Note: Please note that the optical profiles show nominal dimensions. The spot size
diameter or the focal distance may be slightly different due to lens tolerances.

3.4 Alignment 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 measuring a hot object in front of a cooler background, it usually suffices to
align the pyrometer to achieve the highest temperature reading.

4 Settings / Parameter Descriptions

4.1 Factory settings

Emissivity (EMI) = 100%

Exposure time (t

90

) = 0.08 s

4.2 Instrument 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 following 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).

Note: Please make sure that the pyrometer is not contaminated while open.

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.

4.3 Emissivity (EMI)

For a correct measurement it is necessary to adjust the emissivity. This
emissivity is the relationship between the emission of a 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.

IN 5/5 Operating Manual Settings / Parameter Descriptions • 18

Setting examples:

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

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 unpainted area of the object and adjust the
emissivity until the pyrometer displays the same temperature.

IN 5/5 Operating Manual Settings / Parameter Descriptions • 19

4.4 Response time / 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 (t

90

= 0.5 s, 1 s, 2 s or 5 s) select the respective jumper position.

Longer exposure times are useful when measuring objects with fluctuating temperatures.

4.5 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 3.3, 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 pyrometer as well. In this case the location of the pyrometer
should be changed, or, if the background radiation 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 object 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.

7 Troubleshooting

Before sending the pyrometer for repair, try to find the error and to solve the problem with th e
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 3.4).

• Measuring object smaller than spot size.

⇒ Check measuring distance, smallest spot size is at nominal measuring distance (see 3.3).

• Emissivity set too high.

⇒ Set lower correct emissivity slope corresponding to the material (see 4.3).

• Lens contaminated

⇒ Clean lens carefully (see 6.2)

Temperature indication too high

• Emissivity slope set too low.

⇒ Set lower correct emissivity slope corresponding to the material (see 4.3).

• 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 2.6, 6.2).

• 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 3.1).

• Instrument overheated

⇒ Use cooling jacket with air or water cooling (see 2.6).

• Temperature Indication is fluctuating, probably caused by changing emissivity

⇒ Wrong pyrometer type, use of ratio pyrometer recommended
