LTM Level Probe
Overview
The LTM-2 Level Probe works on a potentiometric measuring principle that measures the change in the voltage ratio between the electrode rod of the sensor and the metallic wall of the filled tank. An electric flow field arises in the medium due to the conductivity of the medium and its capacitive properties. This gives rise to a voltage ratio that is proportional to the immersed part of the rod.
Benefits
- Accurate slurry level monitoring, effectively finds the pulp-frot interface
- Conductive working principle, instead of capacitive that is affected by froth buildup
- 1% measurement accuracy
- 1% measurement linearity
- Near instantaneous measurements (100mS)
- Extremely stable operation
- Easy to understand and use
- Little maintenance is required on the system, much less than conventional systems
- Instrument rating is IP 69K so very impervious to water, slurry and dust
- Easy to mount in place
- Less hardware to install and manage
- Complete 316 S/S rod constructions and 304 S/S head construction
Function Principle
This system analyzes electrical resonance properties to detect foam and suppress it in the results, and to reliably prevent erroneous measurements due to adhesions.
Benefits
- Effective Process Control
- Data available for existing PLC, DCS or SCADA
- Additional Parameters available (froth stability, bubble burst rate, froth texture)
- Web based Trending and Reporting
- Simplicity
- High Quality Hardware
- Robust – industrialised for plant conditions
- Remote Support
- Continuous level measurement in metallic vessels up to 3 m in height
- Ideal for adhesive and pasty media
- Level measurement of foaming media
- Minimum product conductivity 1 µS/cm
- Substitute for float sensors
- For media with homogenous conductivity
Examples
- Level control in first running vessels of dosing plants
- Suitable for measuring the level in small vessels with overpressure
- Flotation cell level control
- Sump level control
