Such is basically the static devices which do not have any moving parts. A sine-wave is given to liquid by making use of a reference rod or electrode and such sine wave is triggered by low voltage.

 

Sensing rod or the electrode is being constantly scanned by the electronics, so as to locate the presence of any of sine-wave signal on it and as liquid bridges the 2 electrodes, the signal starts to make the appearance onto the sense-electrode.

 

Finally, the switching output is being given by the device, when it analyses the signal received at the sensing electrode.

Electronics of LSV excites the piezo-electric-crystals inside tuning fork, which makes the fork tines vibrate.

Working Principle:
LSV electronics simply invoke the peizo-electric crystals which are present inside of the turning fork and which enable fork tines to vibrate at their precise resonance frequency while in the free air.

Further, when tines are free to vibrate, the amplitudes of vibration remain above the threshold.

Likewise, when material flows on and touches the fork tines, this event stops vibration since the disturbance in the resonance takes place.

ApplicationIndustrial
Supply Voltage80-260 V AC
Frequency50-60 Hz
Ambient Temperature-10 to 70 deg C
Ingress ProtectionIP65
Relay Output2/3 SPDT

Capacitance is constituted by the probe with the help of metallic tank-wall. Simply put, the capacitance is sum of three capacitance:
  • C(air)=ε(air) × P × (H – L)
  • C(material)=ε(material) × P × L
  • C(residual) is due to device itself.

where ε(air) is the dielectric constant of air ≈1. ε(material) is dielectric constant of material.

P remains constant of probe and installation, H denotes the actual length of probe, while L refers to level of material. Translation from Capacitance to level is done with the aid of on-site calibration, which is also known as “wet calibration”.

There is put a low level capacitance in the device as level for 4mA while the high level capacitance is put to level for 20mA and this is as defined by the user.

Product Details:

Frequency50-60 Hz
Wetted PartsSS-304

Ambient Temperature-20 Deg C to 60 Deg C
Sensor CableRemote electronics with std 10 meters
Relay Rating5 A each @ 24VDC or 220VAC
Process ConnectionNPT / BSP 1", 1 1/4", 1 1/2", 2" etc
Output Limit250mA max. Short Circuit Safe

Working Principle:

RF Admittance is a static level sensor with no moving parts. Its sensing parts are:
  • Earth Extension (body)
  • Compensation Shield
  • Sensing Rod

These parts form three capacitances:
  • Shield Earth Capacitance
  • Shield Sense Capacitance
  • Sense Earth Capacitance

A Sine wave of high frequency is fed into both Sensing Rod as well as Compensation Shield. Voltage at shield is equal to voltage at sense, no effective current flows between sense and shield.

This removes shield-sense capacitance from the measurement. Shield-earth capacitance is ignored by circuit.This removes the effect of material coating on probe.

Bulk is considered as fill-level and “wet” signal is issued
Coating is ignored as insignificant capacitance and “dry” signal is issued.

Compact Vibrating Fork Point Level Switch:

Electronics of LFV11 excites the piezo-electric-crystals inside tuning fork, which makes the fork tines vibrate.
Working Principle

Electronics of LFV11 excites the piezo-electric-crystals inside tuning fork, which makes the fork tines vibrate at their natural resonance frequency in free air.

When fork tines are immersed in liquid, the frequency of fork vibration falls due to the density of liquid.This change in frequency is detected by electronic circuit.Liquid presence is thus detected.

Vibrating rod is a single element tunned mechanical element-type level sensing device.

Electronics of LSV-R excites the piezo-electric-crystals inside tuning rod, which makes the rod vibrate at it’s natural resonance frequency in free air

When material touches the rod, vibration stops as resonance gets disturbed.Amplitudes of vibration are above threshold when rod is free to vibrate Amplitudes of vibration, as seen by the electronics fall below the threshold, Material presence is thus detected by observing the amplitude of vibration.

Application:
  • Free flowing powders and granules.
  • Suitable for side as well as top mounting.
  • Minimum and maximum fail safe field selectable
