Series TFLS Tuning Fork Level Switch is ideal for level control of powders and fine grained solids, especially those with a low bulk density. The TFLS 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 TFLS 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.

The Model TFLS2 Compact Tuning Fork Level Switch is an ideal choice for level control of powders. The TFLS2 incorporates a piezoelectric crystal that vibrates the fork at its natural frequency. When the fork comes in contact with a 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 TFLS2 is user selectable fail-safe operation of the contacts. The unit is not affected by vibration from conveying systems, motors, or the movement of material. Its compact size allows for mounting in places a larger tuning fork level switch may not fit, providing great versatility.

The Model VRLS Vibrating Rod Level Switch is an economical choice in level detection of powders and bulk solids. The VRLS utilizes a piezoelectric crystal that vibrates the rod at a natural frequency. Once the rod comes in contact with the material, the vibration will be dampened and the switch will change state. Once the rod is uncovered by the material, the switch will revert to its normal state. Perfect for silo or hopper applications, its probe design allows for self-cleaning, ensuring no build-up or bridging of material and accurate detection. Sensitivity is adjustable for detection ranging from large granular material to small powders with low bulk densities. The failsafe mode can be set for failure on high level or failure on low level using a selector switch in the enclosure.

Model CLS1 Capacitance Level Switch provides reliable point level measurement of solids, liquids and slurries in metallic or non-metallic tanks and vessels. Model CLS1 detects the presence or absence of material in contact with the probe by sensing a change in the capacitance. Electronics provide highly sensitive measurement detection (requires less than a 1 picofarad shift from ambient). State of the art technology ignores material build-up on the vessel sidewall or along the probe assembly. One time calibration is simple with a single multi-turn potentiometer. Red LED on housing indicates sensor status. Unit features an adjustable 1-30 second time delay and a 5 amp, SPDT fail-safe relay output. Model CLS1 can be mounted vertically or horizontally.
