New pyrometer with fiber optics for temperature measurement from 100°C

The long-standing, proven PYROSPOT pyrometer series 44 from DIAS Infrared has now been expanded with another fiber optic device, the DGEF 44N, for non-contact temperature measurement from 100°C to 1200°C. With its spectral range of 2.0 µm to 2.6 µm, the pyrometer is particularly suitable for measurements on metals and ceramics.

A compact optical heads connected via a fiber optic cable enables ambient temperatures up to 250°C without additional cooling. Several types of optical heads with fixed and vario optics are available for different measuring distances and measurement field diameters from 1.3 mm. Combined with the pyrometer electronics in a stainless steel round housing, this results in a robust device that can be used even in harsh industrial environments.

Like all pyrometers in the PYROSPOT series 44, the device features a temperature linear output 0/4…20 mA, an RS-485 interface (galvanically isolated, Modbus RTU), and a maximum/minimum value storage. An integrated LED or laser aiming light serves as a sighting device. With a minimum response time t₉₅ of 5 ms, the pyrometer is also suitable for fast temperature measurements.

The new devices, among with other PYROSPOT pyrometers and PYROVIEW thermal imaging cameras, will be presented for the first time at the Hannover Messe (booth E54, hall 6) from March 31, 2025.
