ATEX/IECEx/CCC-IS Certified Rugged Pyrometers with HART interface integration
ATEX/IECEx/CCC-IS Certified Rugged Pyrometers with HART interface integration

Fluke Process Instruments expands its Thermalert 4.0 pyrometer series, adding intrinsically safe models and HART protocol as an additional interface option. The rugged, intelligent and compact infrared temperature sensors in an IP65-rated stainless-steel housing are easy to connect via 2-wire installation. The series provides a future-proof, Industry-4.0-ready solution for non-contact, automatic, real-time temperature monitoring. Various spectral models cover a large measured temperature range from -40 °C to 2300 °C and all kinds of industrial applications, such as primary and secondary metals, glass and plastics manufacturing. The new intrinsically safe models rated Ex ib now add infrared thermometer options for use in hazardous environments with potentially explosive gas or dust atmospheres (zones 1 and 21). Accordingly, all models are optionally available with an ATEX/IECEx/CCC-IS certification, with the only exception of sensors with plastic lenses.

Higher operating temperature without need for cooling 

The IR temperature sensors feature galvanically isolated analog and RS485 interfaces. Up to 32 devices can be connected within an RS485 network. All models are also available with connectivity options for Ethernet, EtherNet/IP, PROFINET IO and HART protocol as the latest addition. Voltage can be supplied via Power over Ethernet (PoE). A large choice of optics is available for long and short focal distances. The IR sensors achieve outstanding optical resolutions and provide high-precision data for efficient process control and quality assurance. The Thermalert 4.0 series features an exceptionally high maximum operating temperature of 85 °C, which allows users to save costs by setting up many measuring points without cooling. Moreover, the sensors can be read out, configured, calibrated and fitted with firmware updates remotely via the internet. This minimizes service costs per measuring point. An integrated laser focus facilitates alignment. The easy installation additionally facilitates commissioning and maintenance.
