Features

  • Temperature range: 0°C to 500°C (32 °F to 932 °F)
  • Accurate to ±(0.3% of reading + 2°C)
  • Repeatability: ±(0.1% of reading + 1°C)
  • Temperature resolution (display): 120 mK
  • Ultra-fast 90 µs exposure time
  • The miniaturized head is just 14 mm (diameter) x 28 mm (length) allowing it to fit almost anywhere
  • Usable up to 70 °C (158 °F) without cooling
  • Short wavelength range of 2.2 – 6 µm makes it suitable for measurement of metals, metal oxides, ceramics or materials with unknown or changing emissivity
  • Response time: 300 μs
  • IP 65 (NEMA-4) rated
  • Analog and digital output

The Optris CT 4M infrared temperature sensor is designed for high-speed, low-temperature measurements.

Due to its short measuring wavelength and a temperature range from 0°C to 500 °C (32 °F to 932 °F), the CT 4M, is ideally suited for measuring the temperature of metals, metal oxides, ceramics, or materials with unknown or changing emissivity. The quick response time of only 300 μs along with the ultra-fast 90 μs exposure time allows for problem-free use in fast processes.

The electronics box of the CT 4M allows a flexible terminal device through selectable analog outputs as well as various optional digital interfaces.
