Vibration-based Level Sensing

The sensing element includes two prongs or vanes. When the prongs on the fork are free to vibrate, they are driven to their resonant frequency by piezo ceramic elements. As the level of the material to be sensed rises, the material blocks the movement of the fork. The electronics in the unit sense this change and produce an output that can be used for indication or control. A remote amplifier option is available. The probe can be separated from the amplifier by up to 500m. A high temperature extension allows the unit to handle process temperatures up to 150°C. Smart communications options include GosHawk, DeviceNet, Modbus, Hart and Profibus DP. Hawk Measurementwww.hawkmeasure.com888.429.5538
