Level Transmitter

Product Details:

The principle of Operation:
Top mounted level switches work on permanent magnet reed switch basis. The floats which contain permanent magnets move freely between their stops rising or falling with liquid level movement. Hermetically sealed within the tube are reed switches, completely isolated from the medium. The magnets field actuates the reed switch as the float moves while the stoppers restrict overrun and prevent the reed switch returning to its original position. Stopper positions should not be changed.

Salient Features:
Reed - Switch actuated level switches work on the principle of magnetic flux linkage and therefore they are glandless and leak-proof instruments.
No Power Consumption.
Contacts are potential free, NO, NC or changeover contacts can be provided.
Practically no maintenance is required except periodic cleaning.
As reed-switches are inside a metallic tube-guide pipe, they are protected from mechanical damage.
As the reed switches are "hermetically sealed-in-glass," under an inert gas atmosphere contacts are protected from contamination.
Reed switches, due to their low contact resistance are generally recommended for low voltage application. Reed switches have Rhodium contacts.
Wherever Low Voltage are available 24V or less Reed-Switch actuated level switches may be used directly, Otherwise, it should be used in conjunction with our "Electronic control Unit." This ensures the enhanced life of the level switch.
Reed-Actuated level switches are ideal where vibration is involved.
In a single level switch, we offer a maximum of 5 level sensing.
For highly viscous liquids heavy floats with teflon coated guide pipes are available & also our VMT-EXT models can be used.

Product Details:

The principle of capacitive level measurement is based on change of capacitance. An insulated electrode acts as one plate of capacitor and the tank wall (or reference electrode in a non-metallic vessel) acts as the other plate. The capacitance depends on the fluid level. An empty tank has a lower capacitance while a filled tank has a higher capacitance.
A capacitance is formed between the probe and the vessel wall.As the level of the measuring medium rises or falls capacitancebetween the probe and vessel wall changes proportionately. Ahigh frequency sine wave is applied between the probe andtank wall. A change of medium level will induce a change in thecurrent of the applied sine wave. From when thecapacitance in the vessel increase, impedance will decreaseand current will increase and vice-versa

Head mounted electronics converts the capacitance variation to 4-20mA signal for long distancetransmission. It is provided with trimpots for SPAN and ZERO adjustments. With no moving partsit is free from wear and tear, rugged and robust in construction. No dead zone like float basedinstruments.It must be ensured that the probe is parallel to the tank wall throughout it's length.
