Product Overview

The Thermalert TX infrared temperature sensors are available with remote addressability, easily installed in multidrop configurations.

TX Series Smart Sensors communicate over a simple loop-powered 2-wire cable using the HART (Highway Addressable Remote Transducer) protocol. This signal combines industry-standard 4-20 mA output with simultaneous digital communications. They include Raytek DataTemp® Multidrop software, providing an easy-to-use interface for configuration and monitoring. Temperatures can be archived or exported to other applications for analysis and process documentation. 

Smart TX sensors feature remotely adjustable temperature and output subranges, adjustable emissivity, ambient temperature check, and a user-defined alarm output. Averaging and Advanced Peak/Valley Hold algorithms are provided for accurate measurement of complex discrete processes.
