The Honeywell model 705 high-temperature sensor detects flammable gases in high-temperature hazardous area locations. Applications include turbine enclosures and drying ovens used in solvent-based printing and coating machines.
The 705 HT incorporates a matched pair of Sieger poison-resistant flammable gas detection elements; the 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.
Aluminium explosion-proof assembly, fully encapsulated, designed for use in hazardous locations. Use a junction box for catalytic bridge output or with Sensepoint RFD transmitter for local display and 4-20mA output.
