LAND Understrip Thermometer

The systems are easy to install and designed for trouble-free operation. A low cost sighting tube/purge unit houses a readily demountable modular fiber optics probe. The associated electronic amplifier unit, located remotely, is linked by a sealed fiber optics light guide. An air line, connected to the sighting tube, to provide a purged sight path for the thermometer, is the only service required by the thermometer optic head. The electronics unit is provided with electrical power from the associated System 4 Landmark Graphic signal processor. The processor provides electronic signal treatment of the thermometer output allowing averaging, peak picking or sample and hold outputs and temperature display. An optional serial communications facility gives digital RS232C or RS422A outputs and allows access for system parameter adjustments from a remote computer.
