  • Choose from options of analogue and digital communication protocols




Fluke Process Instruments has launched the Thermalert 4.0 spot pyrometer series for automatic noncontact temperature monitoring between -40 °C and 2,250 °C. The series currently comprises 13 models with varied spectral responses, including dedicated sensors for metals, glass, and plastics products. A large choice of optics is available for long and short focal distances.

Smart pyrometers for plug & play factory automation

Due to the outstanding ambient temperature range of -20 °C to 85 °C, more measuring points can be set up without cooling accessories and without installing cooling media supplies. Accordingly, there is no danger of leakage and contamination of critical processes. The rugged IP65 infrared thermometers come as standard in a stainless steel housing and exhibit best-in-class repeatabilities, response times, and accuracies. These functions can significantly lower service costs and time spent on setup and troubleshooting. The sensors feature galvanically isolated analog and RS485 interfaces. Up to 32 devices can be connected within an RS485 network. The manufacturer will keep on adding fieldbus and feature options in future. Retrofit of existing measuring points has been made as easy as possible. The new sensors can be fitted in fixtures for Endurance, Raytek Thermalert TX, and Raytek XR pyrometers. Adapters are available for use with Ircon Modline 4 and Raytek MM fixtures.
