Infrared pyrometer.

The Thermalert® 4.0 is a versatile infrared spot pyrometer for automatic, noncontact temperature measurement in harsh industrial environments. Launched by Fluke® Process Instruments it is 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.

Backed by 150 years of industrial experience, the Thermalert 4.0 is a smart, integrated sensor providing temperature measurement performance suitable for demanding factory automation applications. 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.

Compact and rugged, the Thermalert 4.0 provides best-in-class repeatability, response time, and accuracy. The advanced 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.

Reliable and easy to operate, the new pyrometer delivers outstanding optical resolution. 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. 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 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.
