SC35 Tuning Fork Level Switch

SC35 Tuning Fork Level Switch is ideal for level control of powders and fine grained solids, especially those with a low bulk density. The SC35 incorporates a piezoelectric crystal that vibrates the fork at its natural frequency. When the fork comes in contact with material, the vibration is dampened and the switch changes state. As the fork becomes free of material, the switch changes back to its normal state. Featured in the SC35 is user-selectable fail-safe operation of the contacts. Unit is not affected by vibration from conveying systems, motors, or the movement of material. It can be mounted in any position and is available with factory built extensions for mounting on the top of the storage vessel.

  Features

No Calibration Required. Vibrating Fork Design: Great for low bulk density and low dielectric constant products. Will detect products down to 155mm min ≧0.01 g/cm3. Universal Power Supply: One model works with 19~253 VAC and 28 VDC Adjustable Sensitivity: Can be set to ignore lighter bulk density products and only detect heavier products, such as sand in water. Status Indication: External LED indicator, and internal indicators for normal and alarm status. Failsafe Setting: Output switch can be set for Normally Open or Normally Closed condition on loss of power. Time Delay: Prevent false alarms from material surges. No Maintenance Required. Any Position Mounting: Available with factory built extensions for mounting on the top of the storage vessel
