Switching inputs Supplementary lenses Both switching outputs can also be operated as switching inputs for: • Control memory reset command • Activate the laser spot light Interfaces The CellaTEMP® PA features a USB interface and a network compatible RS-485 bus interface. The pyrometer can be parameterized via both interfaces. The RS-485 interface is suitable for transmitting measurement data over long distances to a central data acquisition system. An English communication software is already integrated into the CellaTEMP® PA. This allows the pyrometer to be operated from any PC or terminal, regardless...

L aser spot light As a further option, the CellaTEMP® PA features an integrated laser spot light. The laser dot marks the center of the target spot and is well visible even from a distance of up to 10 m. The laser is activated either directly by push-button, via interface or by an external switch. ideo camera V Alternatively, the pyrometer can be equipped with a built-in colour video camera to view the target. The HDR (High Dynamic Range) camera features a novel, automatic exposure control with a very large dynamic range. This ensures the video image is always optimally illuminated without over-exposuret....

The measurement starts automatically upon detection of the hot object. The measuring time adapts dynamically to the dwell time of the object in front of the pyrometer or can be manually configured. At the end of the measurement, the determined measured value is available at the outputs for further processing. Diagnostics feature Via the diagnostics feature, a temperature value or a current value can be output via the analogue output during setup or running operations for simulation purposes. Without requiring a hot object, the correct function and scaling of the downstream transducers or PLC...

>>> Pyrometers for special applications_ CellaTEMP" PA 13 for flame heated furnaces_ The CellaTEMP" PA 13 was especially developed for temperature measurements in flame heated furnaces. Thanks to the selective spectral range of 3.9 pm, water vapour and CO2 existing in the pyrometer's field of vision have no effect on the measuring results, even when measuring from large distances. This allows precise measurements through flames and combustion gases. CellaTEMP" PA 15 for glass measurement_ In the range of 4.6 - 4.9 pm glass has an emissivity of almost 100%. Above 5 pm, atmospheric influences,...

CellaTEMP" PA 35 for high-temperature processes and silicon wafers The CellaTEMP" PA 35 features a very short-wavelength, narrow-band spectral response. As a result, the pyrometer is less sensitive to interference caused by dust, steam, or smoke within the field of view, contamination of the protective window, and variations in the emissivity of the target object. This ensures highly accurate and stable temperature measurement of metals and other materials in high-temperature processes. In addition, the CellaTEMP® PA 35 is ideally suited for temperature measurement of silicon wafers. In the short-wavelength...

The two-colour pyrometer detects the infrared radiation emitted from an object's surface simultaneously at two separate wavelengths using a dual sandwich detector. The temperature is determined based on the ratio of these two radiation intensities. The advantage of the two-colour technique is that the pyrometer will still produce a correct measurement value, even at signal attenuation of up to 90%. The two-colour pyrometer is far less sensitive to contaminants in the line of sight such as steam, dust or smoke than a conventional single-colour pyrometer. Even if the pyrometer's optics or the furnace's...

The Panorama pyrometer" of the CellaTEMP” PA 43 series features a rectangular measurement area. This is realized purely optically, i.e. without moving parts. Within the measurement area, the target object can move freely. This makes it possible to reliably capture the temperature of moving objects such as swaying wires. A rectangular measurement field is also more advantageous when the position of the target object varies, for example when measuring billets or metal rods on a roller table. For very small objects, aligning the pyrometer with a rectangular measurement field is much easier. The...

fibre optics pyrometer_ A pyrometer with fibre optics has the sensor head housed separately from the electronics assembly. A fibre optic cable transmits the infrared radiation from the measuring head to the electronics. The measuring head can withstand ambient temperatures up to 260 °C without cooling. The fibre optic pyrometer is also used in high electromagnetic fields or cramped, hard-to-access locations. Three different focusable optical heads are available, depending on the required target size and measuring distance. To check the measurement position and adjust the focusing, the pyrometer...
