The Sensepoint 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. Utilising a specially matched pair of Honeywell poison resistant combustible gas detection elements, the Sensepoint 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 -55°C to +150°C (-67°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 an 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
