FTCT-3M Infrared Temperature Sensor

Ideally suited for employment in low-temperature measurements of metals and composite materials

About the FTCT-3M Infrared Temperature Sensor

Due to its short measuring wavelength and a temperature range from 50°C (122 °F) on, the pyrometer FTCT-3M, is ideally suited for employment in low-temperature measurements of metals and composite materials. The quick response time of only 1 ms allows for a problem-free use of the metal thermometer in fast processes.

The electronics box of the measuring device allows a flexible terminal device through selectable analog outputs as well as various optional digital interfaces.

The IR thermometer optris FTCT-3M has a measuring wavelength of 2.3 µm and is thus employed in temperature measurements of metallic surfaces and composite materials in processing. Especially its low temperature range from 50°C (122 °F) on make the temperature sensor a popular measuring device for every kind of low-temperature measurement of metals.

Features FTCT-3M

  • Miniaturized Infrared Thermometer with 2.3µm wave length range for measurements of metals, of secondary metal processing, metal oxides and ceramic materials
  • Very small sensing head of 14mm diameter and 28mm length fits everywhere and is usable up to 85°C ambient temperature without cooling
  • Temperature measuring ranges from 50°C to 1800°C and exposure times starting from 1ms
  • Short wave length range of 2.3µm to reduce error of reading with measurements on materials with unknown emissivity
