T3-390
Temperature Range: 300°C to 1400°C
Highly Accurate On-Line Infrared Non-Contact Pyrometer in Two Wire Technology
T3-390 PL IR Pyrometer model provides the advantage of noncontact temperature measurement of metallic surfaces and in flame heated furnaces i.e through flames and flue gas. At a wavelength of 3.9um hot furnaces gases and clean burning gas flames are quite transparent and therefore permit temperatures of substances to be measured as well during heating up process in industrial furnaces with the use of infrared Pyrometer T3-390 PL. This format combines the high accuracy of digital signal processing with the simple connection.
T3-390 PL IR Pyrometer is used for target temperature ranging from 300°C to 1400°C. The electronic assembly is protected by IP65 rugged stainless steel housing. The parameters like Emissivity can be adjusted directly at device. Other parameters like Analog Sub Range, Response Time, Peak Picker etc can be preset ex-works or adjustable via Software Infrasoft. T3 Series is provided with TTL output. Using the USB interface Infralink and Software pyrometer can be connected to PC for parameter setting and data logging.
