Fisher 249 Series Caged Sensors
Fisher 249 caged level sensors provide more stable operation than do cageless sensors for vessels with internal obstructions or considerable internal turbulence. These sensors are designed to measure changes in liquid level, liquid interface level, or density/specific gravity inside a process vessel using Archimedes’ Principle.
- The torque tube can be replaced without removing the torque tube arm.
- Fisher 249 caged level sensors few moving parts are used. A knife-edged driver bearing in the sensor helps to provide low-friction operation.
