The Honeywell Analytics 705 high-temperature sensor has been specifically designed for the detection of combustible gases in high-temperature hazardous area locations. Typical applications include turbine enclosures and drying ovens used in solvent-based printing and coating machines.

These applications require a sensor that provides reliable and stable detection allowing low-level alarm settings across a wide temperature range. Utilizing a specially matched pair of Sieger poison resistant combustible gas detection elements, the Model 705 High Temperature Sensor has a very stable baseline allowing alarm trip points to be set as low as 5% LEL across a temperature range of -25°C to +150°C (-3°F to +302°F). The gas measuring range can be configured from 0-20% LEL up to 0-100% LEL depending on the type of controller used. 
The detector elements are housed in a UL hazardous area approved explosion proof assembly, and provide an industry standard 3 wire mV bridge output which can be connected to a suitable control device or converted to an analog output signal via a field transmitter.
