Impac ISR 320 Series Pyrometers

Active

Compact, digital ratio pyrometer with fixed optics and LED targeting light for non-contact temperature measurements on metals, ceramics, graphite, etc. Temperature ranges between 700 and 2500 °C.

The Impac ISR 320 is a stationary, digital, compact, and fast two-color pyrometer for non-contact temperature measurement in temperature ranges between 700 and 2500 °C. The pyrometer measures in the two-color method (ratio method) in which two adjacent wavelengths are used for the temperature determination. Using the two-color method, temperature measurement is largely independent of the object’s emissivity. And in wide ranges, measurement is unaffected by dust and other contaminants in the field of view. The measuring object can be smaller than the spot size. Measurements can be made through dirty-viewing windows up to a certain contamination point.

Features

  • Small housing dimensions for easy installation 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

Benefits

  • Use like a conventional pyrometer when needed by switching to the one-color mode
  • Measure objects smaller than the spot size
  • Store measurement values
  • Easily set up pyrometer parameters
  • Make measurements through dirty-viewing windows
