May 31, 2018 -- Fluke Process Instruments announced the Thermalert 4.0, an infrared spot pyrometer for automatic, noncontact temperature measurement in harsh industrial environments. Intended for use with temperatures of -40 °F to 4,082 °F (-40 °C to 2,250 °C), the pyrometer series comprises 13 models with varied spectral responses, including dedicated sensors for metals, glass, plastics, paper and food products.
The Thermalert 4.0 is a smart, integrated sensor providing temperature measurement suitable for factory automation applications. The device offers a choice of optics for long and short focal distances, and its 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 Thermalert 4.0 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. Plug & play operation further facilitates installation and maintenance.
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 for the future.
A 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 challenging environments, the ThermoJacket is recommended.
This cast aluminum housing protects the sensor in ambient temperatures to 600 °F (315 °C).
The Thermalert 4.0 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.
