Flexible gauge
Flexible intrinsically safe gauge for tank level measurement Master Level serie CPT05510
CPT05510 Flex is a level and environmental sensor which is especially designed for large storage tanks.
When the installation of the CPT05510 Flex level sensor has been completed, the corrugated tube is positioned vertically and both the product and the water floater can freely move up and down.
The CPT05510 Flex sensor works according to the magnetostrictive measuring principle. A wire made of magnetostrictive material has been integrated into the flexible tube.
The special design of the sensor allows the sensor body to bend so the CPT05510 Flex can be packed compactly and shipped at low cost. Another advantage is the easy installation. A weight at the lower end of the sensor stretches it out to its full length, and a magnet placed below the weight secures the sensor to be in place. When the magnet is in contact with the bottom of the tank (after installation) any unintentional movement of the CPT05510 Flex is avoided.
