SKU: DM401
Highlights
- Measuring Principle/ sensor type: Non-contact infrared temperature sensors
- Measuring/Operating Range: DM 1ML: 485 to 1800°C; DM 2ML: 250 to 1600°C; DM 1MH: 650 to 1800 °C
- Accuracy: ±(0.3 % of reading +2°C)
- Short response time of 1 ms
- Spectral range: 1 or 1.6 μm
Fields of application
- Temperature measurements requiring short measuring wavelengths
- Precise and reliable measuring of metallic suraces in metal processing (e.g. welding, sintering) as well as metal oxides and ceramics
Details
Due to the short measuring wavelength and the high temperature range of up to 2200°C the pyrometers of the DM401 series are ideally suited for high-temperature measurements of metals, metal oxides, and ceramics. The small sensor head allows for easy installation in limited and cramped spaces. Moreover, it reliably measures temperatures even in ambient temperatures of up to 125°C.
