2 Introduction The MC320 represents another milestone in innovative infrared thermal imaging. Designed with advanced maintenance-free electronics and industrial protective packing, the MC320 offers unparalleled accuracy for demanding industrial and scientific applications. With an unmatched array of protective accessories, the MC320 demonstrates LumaSense’s commitment to long-term trouble-free operation of these instruments.
Integration with other devices in the process or other systems (PLCs, computers, SCADA and Distributed Control Systems (DCSs), other sensing devices, actuators, etc.) Housings and enclosures matched to the harsh environment (explosive, hazardous, outdoor, etc.) Custom-designed mechanical hardware Communication links Startup support LumaSense engineering staff and sales consultants follow a system approach to online thermal processing control.
2.3 Lenses Caution: Do not use thinners, benzene or other chemicals to clean the lens as these will damage the lens coating. The MC320 is a process camera that has a full array of optional lenses available to meet the needs of most applications. However, because of the extreme and application-specific nature of the camera system, it is necessary that the appropriate lens be fitted and calibrated at the LumaSense Factory according to the application requirements.
Before shipment, each camera is assembled, calibrated, and tested at the LumaSense Factory. If you note any damage or suspect damage, immediately contact the carrier and LumaSense Technologies, Inc. 2.6 Storage In case the instrument is not put into service immediately, it should be tested in the application or simulated application as promptly as practical to reveal any hidden damage. Unpleasant surprises can be avoided by briefly trying the instrument before putting it in storage.
2.8 Shipments to LumaSense for Repair All RMA shipments of LumaSense Technologies instruments are to be prepaid and insured by way of preferred carrier. For overseas customers, ship units air-freight, priority one. The instrument must be shipped in the original packing container or its equivalent. LumaSense Technologies is not responsible for freight damage to instruments that are improperly packed. Clearly indicate the assigned RMA number on the shipping package exterior.

3 Getting Started The MC320 camera is configured to operate under certain conditions according to user-defined specifications. As such, the camera is assembled, calibrated, and tested at the LumaSense Factory and is delivered with the necessary components to create a fully-operational system. Assemble the system by connecting the cables as shown on the System Configuration and Wiring drawing supplied with the system.
3.4.1 Connecting the Camera to a Dedicated Computer Connecting the MC320 to a computer using a crossover cable To Connect the Camera to a Dedicated Computer: 1. Connect one end of the RJ45 (Ethernet) crossover cable to the Ethernet port on the camera and the other end to the computer. 2. Connect the camera power supply to the camera. 3. Turn on the computer to connect the camera to the computer. 4.
3.4.2 Connecting the Camera to a Network Device Connecting the MC320 to a computer using a patch cable To Connect the Camera to a Network Device: Note: The MCL320 requires a Gigabit Ethernet network adapter. An appropriate adapter will be supplied with the camera. All cabling should be Cat 5e or Cat 6. MC320 Thermal Imager Manual 1. Connect one end of an RJ45 Ethernet patch cable to the Ethernet port on the camera and the other end to the switch. 2.
3.5 Installing the Software If your system was delivered with LumaSense’s thermal imaging software, then you have available all the necessary executables and support files needed for remote camera control operations. For information on installing and using the software, refer to the software manual that came with your system. 3.6 Working with the Camera System Your LumaSense software was shipped with preconfigured camera settings based upon the system you purchased.
4 Principle of Thermal Imaging All materials above 0 degrees Kelvin (-273 degrees C) emit infrared energy. The infrared energy emitted from the measured object is converted into an electrical signal by the imaging sensor in the camera and displayed on a monitor as a color or monochrome thermal image. The basic principle is explained in the following sections. 4.
4.2 Emissivity Infrared radiation is energy radiated by the motion of atoms and molecules on the surface of object, where the temperature of the object is more than absolute zero. The intensity of the emittance is a function of the temperature of the material. In other words, the higher the temperature, the greater the intensity of infrared energy that is emitted. As well as emitting infrared energy, materials also reflect infrared, absorb infrared and, in some cases, transmit infrared.
Note: A blackbody is a theoretical surface, which absorbs and reradiates all the IR energy it receives. It does not reflect or transmit any IR energy. Perfect blackbody surfaces do not exist in nature. Where, Wo = total radiant energy emitted by a body at a given temperature T. Wbb = total radiant energy emitted by a blackbody at the same temperature T. If all energy falling on an object were absorbed (no transmission or reflection), the absorptivity would equal to 1.
Where in (1) to (3), In radiation of a normal object, as the emissivity is (<1) times of the blackbody, multiply above equation by the emissivity. The following figures show the spectral radiant emittance of a blackbody. (a) is shown by logarithmic scale and (b) is shown by linear scale. Spectral radiant emittance of a blackbody The graphs show that wavelength and spectral radiant emittance vary with the temperature.
Absorptivity equals emissivity, thus emissivity can be described by reflectivity and transmissivity. e+t+r=1 In order to obtain the true temperature of an object, it is necessary to obtain the emissivity correctly. Therefore, the emissivity of the object has to be measured by using a blackbodytype source which is closest to an ideal blackbody as possible.
1. By means of a printed table Various books and literature carry physical constants tables, but if the measuring condition is not identical, the constants may not usable. In such cases the literature should be used only for reference. 2. Determination by ratio — Option 1 A contact-type thermometer is used to confirm that the measured object is in thermal equilibrium and that the blackbody-type source is at the same temperature.
4.6 Background Noise Note: For low temperatures, masking tape or cornstarch can be used. When measuring the temperature of an object by a radiation thermometer, it is important to take into consideration the above-mentioned emissivity correction as well as the environmental conditions where the measurements will be performed. Infrared rays enter the thermal imager from the measuring object as well as all other objects nearby.
4. Thereafter when measuring the same type object, it is unnecessary to change the emissivity setting. 2. Method of direct measurement of emissivity If a hole cannot be made as in method 1, then apply black high emissivity paint and carry out the same procedures to obtain the emissivity. Since the black paint will not provide a perfect blackbody, first set the emissivity of the black paint and then measure the temperature. 3.
