Switching inputs Supplementary lenses Both switching outputs can also be operated as switching inputs for: • Control memory reset command • Activate the laser spot light Data communication The CellaTemp® PA features a USB interface and a network compatible RS-485 interface to enable remote pyrometer configuration. Beyond that, the RS-485 also provides network communication capabilities and permits long distance data transmission. Because of its integrated software, the CellaTemp® PA can communicate with all commonly used operating systems at any PC or terminal, regardless of language. The...

Control keys Laser spot light The third sighting option available for CellaTemp® PA is 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 or remote by means of an external switch or via interface. Video camera As an option, the pyrometer can be equipped with a built-in colour video camera to view the target. Based on the latest HDR (High Dynamic Range) technology, the camera provides a higher dynamic range from the imaging process and automatic...

With ATD, objects moving across the pyrometer‘s field of view at undefined intervals are automatically detected. Examples include rolled steel slabs at a rolling mill stand or billets discharged from an induction heating system. ATD (Automatic Temperature Detection) is an optional feature especially useful for temperature control at discontinuous processes. With ATD, CellaTemp® PA automatically recognizes a hot object and starts measuring the temperature. The measuring cycle either adapts dynamically to the duration of the object in the sight path, or it can be custom configured by the...

The CellaTemp PA 35 features a narrow-band, short wavelength spectral response to minimize the effect of interferences which lead to measurement errors. Detectors which respond to narrow wavebands at short wavelengths are far less susceptible to dust, steam, smoke or a dirty lens. Metal surfaces, for example, exhibit higher emissivity at shorter wave-lengths and at higher temperatures. Due to the special wavelength, it is especially suitable for temperature detection of metals and high-temperature applications or thin semiconductors. The CellaCrystal PA 45 two-colour pyrometer is...

Compact two-colour pyrometer TQ ≈ spectral specific radiation The two-colour pyrometer detects the infrared radiation emitted from an object‘s surface at two separate wavelengths. The dual sandwich detector uses a two-element photo-diode to capture both radiation intensities simultaneously from the exact same spot. The pyrometer produces temperature data based on the ratio of these two intensities. The advantage of the two-colour or dual wavelength technique is that the pyrometer will still produce highly accurate temperature data, even at signal attentuation of up to 90%. The two-colour or...
