Pyrometers for high temperatures and various fieldbuses
Published: 18 November 2019 - Sarah Mead
Fluke Process Instruments extends its Thermalert 4.0 spot pyrometer series, adding new shortwave versions and various additional interface options.
The compact, extremely robust infrared thermometers provide noncontact, automatic temperature monitoring. Three new spectral models measuring at wavelengths of 1 µm, 1.6 µm, and 2.3 µm have been primarily designed for high-temperature applications and are particularly suitable for monitoring metal, steel, and glass. The full Thermalert 4.0 lineup covers measuring temperatures between -40 °C and 2300 °C and offers various different spectral models and focus distances.
All models are now available with connectivity options for Ethernet, EtherNet/IP, and PROFINET IO, in addition to analog or RS485 interfaces. Voltage can be supplied via Power over Ethernet (PoE). The Thermalert 4.0 series features an outstanding high maximum operating temperature of 85 °C. Users can therefore save costs by setting up many measuring points without cooling.
