Basics
16 Rev. E3 07/2013MP150
3Basics
3.1 Measurement of Infrared Temperatures
Every object emits an amount of infrared radiation (IR) according to its surface temperature. The
intensity of the infrared radiation changes with the temperature of the object. Depending on the
material and surface properties, the emitted radiation lies in a wavelength spectrum of approximately
1 to 20 µm. The intensity of the infrared radiation (”heat radiation”) is dependent on the material. For
many substances this material-dependent constant is known. It is referred to as ”emissivity value”, see
appendix 10.2 Typical Emissivity Values on page 57.
Infrared thermometers are optical-electronic sensors. These sensors are able to detect ”radiation of
heat”. Infrared thermometers are consist of a lens, a spectral filter, a sensor, and an electronic signal
processing unit. The task of the spectral filter is to select the wavelength spectrum of interest. The
sensor converts the infrared radiation into an electrical signal. The connected electronics process this
signal for further analysis. The intensity of the emitted infrared radiation is thereby used to determine
the temperature of the target. Since the intensity of the infrared radiation is dependent on the material,
the appropriate emissivity can be selected on the sensor.
The biggest advantage of the infrared thermometer is its ability to measure temperature without the
need to be in contact with the target. Consequently, surface temperatures of moving or hard to reach
objects can be easily measured.
3.2 Emissivity of Target Object
For accurate temperature readings, the sensor must be set to the appropriate emissivity value for the
target material. Determine the emissivity of the target object as described in appendix 10.1
Determination of Emissivity on page 57.
When measuring materials with low emissivity, the results could be effected by interfering infrared
radiation from background objects (such as heating systems, flames, fireclay bricks, etc. near to or
behind the target object). This type of problem can occur when measuring reflective surfaces and very
thin materials such as plastic films and glass. This error can be reduced to a minimum if particular
care is taken during installation, and the linescanner is shielded from reflected infrared radiation.

System Overview
MP150 Rev. E3 07/201317
4System Overview
The following figure shows the principal structure of the system. It shows a solution with one scanner,
one Digital Output Module and one Analog Output Module. The system can be expanded by adding
more Output Modules to the RS485 network, see section 7.9 Output Modules, page 44.
Figure 6: Principal structure of the system
Instead of outputting the temperature data by means of output modules also an OPC server capability
or a serial communication port can be used for forwarding the data to other control systems, e.g. a
PLC.

Installation

5Installation
Linescanners are able to measure temperature values along a line through the use of a rotating mirror.
For 25% of its revolution, the linescanner scans the field of view (FOV). This corresponds to a scan
angle of 90°. The remaining 75% of its revolution is used for the internal operation of the sensor. The
rotating mirror views the scene and reflects the infrared energy striking it onto a system of lenses
which focuses the radiation onto a thermoelectrically cooled detector. The incoming signal is scanned,
digitized, and then converted to temperature values by the internal microprocessor. For every
revolution of the mirror, up to 1024 measured values will be internally collected. An air purge system
keeps the scanner’s window free of dust, debris, and condensation.
5.1 Ambient Temperatures
Without water cooling, the linescanner is designed for ambient operating temperatures between 0°C
and 50°C (32°F and 122°F). With water cooling, it can be used in environments of up to 180°C (356°F),
see section 5.9 Water Cooling, page 26. The internal temperature is the determining factor for proper
operation of the linescanner. It is displayed in the DataTemp software. The difference between the
external ambient temperature and the temperature inside the housing also depends on the thermal
contact of the linescanner and its mounting hardware.
The temperature inside the housing must be between 0°C to 60°C (32°F to 140°F) during
operation and never more then 65°C (150°F) at any time, including non-operation!
5.2 Environment
The linescanner complies with class IP65 and is therefore dust and splash resistant. The linescanner’s
window is made of a material that is resistant to thermal stresses and it is equipped with an integrated
air purge system which protects the window against contamination. Air supply for the air purge
should be oil free, clean “instrument“ air.
5.3 Electrical Interference
To minimize electrical or electromagnetic interference, follow these precautions:
•Mount the sensor as far away as possible from possible sources of interference such as
motorized equipment producing large step load changes!
•Ensure a fully insulated installation of the sensor (avoid ground loops!).
•Make sure the shield wire in the sensor cable is earth grounded at one location!
•To avoid potential differences use a single power circuit to power both the linescanner and the
PC running the software!
5.4 Geometry
The smallest possible object which can be measured depends on two conditions:
1. The area measured must be no less than 90% (90% energy response).
2. Hot spots must be clearly detected, when in front of a cold background (50% energy response).
Remark: The measured area for 50% energy response is approximately ⅓ of the area size of the
measured spot for 90% energy response.

Installation
MP150 Rev. E3 07/201319
Refer to section 2.2 Optical Specifications, page 9, for basic versions of optical resolution values for the
various models.
Figure 7: Relationship between scan line width and distance to target
The relationship between the scan line width (L) and the distance (D) to the front side of the
linescanner housing is defined as described above. For long distances, the scan line width is about
twice the measurement distance (90° FOV).
5.5 Mounting
The linescanner can be installed as follows:
•on a tripod with a standard 1/4-20 UNC (photo equipment) thread. This type of setup requires
the optional tripod mounting plate (XXXTMP50ACCC) and is recommended if the linescanner
is to be used only for temporary or mobile measurements.
•with the mounting holes of the linescanner housing. This type of setup is recommended for
permanent installations where higher stability is desired.
Prevent all contact between heat sources and the linescanner to protect the linescanner from
overheating.

5.6 Communication Interfaces
The MP150 can communicate via Ethernet interface or RS485. During system configuration the user
selects either Ethernet or RS485. You cannot use Ethernet and RS485 communications for the data
transfer at the same time!
The Ethernet connection between linescanner and the PC has a maximum speed of 100 MBit/s and
permits real-time data transfer for all temperature pixels. For multi-scanner systems you can use a
standard Ethernet Switch to connect to the PC network adapter.
5.6.1 Ethernet Wiring
The linescanner is shipped with an Ethernet cable specified to NEMA WC-63.1 Category 5e, UL
verified to Category 5e, Ethernet/IP Compliant. This standard cable is 7.5 m (24.6 ft.) long, free from
Halogen, and withstands ambient temperatures up to 180°C (356°F).
The connector on one cable end (scanner wiring) is an M12 plug-in connector, 4 pin D-coded, suited
for industrial Ethernet with IP67 protection rate with a screw retention feature.
The connector on the other cable end (field/PC wiring) is an RJ45 connector.
