Infrared Pyrometer Tackles Diverse Temperature Applications

Fluke Process Instruments introduces the Thermalert 4.0, a versatile infrared spot pyrometer for automatic, noncontact temperature measurement in harsh industrial environments. Intended for use with temperatures from -40°F to +4,082°F (-40 °C to 2,250 °C), the pyrometer series comprises 13 models with varied spectral responses, including sensors for metals, glass, plastics, paper and food products. The device offers a choice of optics for long and short focal distances, and its exceptional ambient temperature range of 68 °F to 185 °F (-20 °C to 85 °C) enables measuring points to be set up without any extra cooling.

 

The IP65/NEMA4 instrument employs real-time background temperature compensation and laser aiming, and its DataTemp Multidrop system software supports remote configuration, monitoring, field calibration, and firmware updates. These functions can significantly lower service costs and time spent on setup and troubleshooting. Plug & play operation further facilitates installation and maintenance.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

Two-wire loop-powered, RS-485 and analog outputs are available to meet diverse user requirements. In addition, galvanic insulation ensures correct readings. Up to 32 devices can be connected as part of an RS485 network. Additional fieldbus options are planned. Moreover, retrofit of existing measuring points has been made as easy as possible.

 

A wide variety of options and accessories are available to customize the installation of Thermalert 4.0 sensors. Lens protectors and air purge collars offer protection under severe conditions. Water- and air-cooled housings can be specified for operation in ambient temperatures up to 315 °F (175 °C). For extremely challenging environments, the ThermoJacket is recommended. This rugged cast aluminum housing protects the sensor in ambient temperatures to 600 °F (315 °C).

 

The Thermalert 4.0 page. is backwards compatible with legacy Raytek and Ircon; sensors, and can be equipped with fixtures for Endurance, Thermalert TX, and XR pyrometers. Adapters are available for use with Modline 4 and Marathon MM fixtures. For more information, visit the Thermalert 4.0 page.
