bi-color pyrometer / digital / fixed
Min.: 700 °C (1,292 °F)
Max.: 1,700 °C (3,092 °F)
Small, stationary, digital ratio pyrometer for non-contact temperature measurement between 700 and 2500 °C mA to 20 mA. In addition, its working temperature is 700 °C to 1700 °C.
Small housing dimensions for easy installation, suitable for use in confined spaces
Fast 10 ms response time for dynamic processes
RS485 interface for long transmission networks for connection to a PC via USB converter or machine control (PLC)
Analog output adjustable to 0 to 20 mA or 4 to 20 mA for connection of standard analyzing instruments
Internal digital signal processing for high accuracy
Built-in LED targeting light for easy alignment to the measuring object
Thermal intensity alignment using intensity indicator LEDs at the backside of the instrument
Integrated Dirty Window warning
The pyrometer ISR 320 measures in the 2-color method (ratio method) in which two adjacent wavelengths are used for the temperature determination.
This technique offers the following advantages compared to standard 1-color pyrometers:
The temperature measurement is largely independent of the object’s emissivity and in wide ranges unaffected by dust and other contaminants in the field of view.
The measuring object can be smaller than the spot size and measurements through dirty viewing windows are possible up to a certain contamination.
The pyrometer can also be switched to 1-color mode and used like a conventional pyrometer in a spectral range near 0.9 μm.
The included InfraWin software enables graphical display and storage of measurement values, as well as easy set-up of all instrument parameters.
