VITAL- Vibrating Fork Level Sensor/Switch for Solids
Item Code: VITAL
- Application Temperature Range : up to 200° C
- Fast Switching: 0.5s , 0.8s options available
- Calibration Free, independent of material's dielectric properties
- No moving parts, longer running life
- Outputs: DPDT Relay, Open Collector PNP Output
- Certifications: Flame Proof Housing IIC, IP-68 Housing
Principle
A specially shaped tuning fork is kept vibrating using piezo-electric elements. The oscillation of the fork damps when in contact with the material. The loss of oscillation amplitude is detected and used for switching a relay. The output contacts of the relay are in turn used for annunciation and/or control.
Benefits
- Better immunity to external vibrations
- Polished finish for hygienic applications
- Shorter Probe Lengths
- Self Diagnosis
