The tried-and-tested pyrometers of the PYROSPOT Series 44 from DIAS Infrared have recently been expanded to include another fibre optic device, the DGEF 44N, for non-contact temperature measurements from 100 to 1200 degrees Celsius. With its spectral range of 2.0 to 2.6 micrometres, the pyrometer is particularly suitable for measurements on metals and ceramics, according to the developer.

A compact attachment connected via an optical fibre allows ambient temperatures of up to 250 degrees Celsius without additional cooling. Several types of attachment optics with fixed and variable optics are available for different measuring distances and measuring field diameters from 1.3 millimetres. Together with the pyrometer electronics in a stainless steel round housing, the result is a robust device that can also be used in harsh industrial environments.

Like all pyrometers in the PYROSPOT 44 series, the device has a temperature-linear output of 0/4...20 milliamps, an RS-485 interface (galvanically isolated, Modbus RTU) and a maximum/minimum value memory. An integrated LED or laser pilot light is available as a sighting device. With a minimum response time t95 of five milliseconds, the pyrometer is also suitable for fast temperature measurements.
