SMARTsaa offers Radar Level Transmitter for monitoring levels of solids, powders, granules and liquid by non contact way. Radar Level operates on the principle of Time domain reflectometry principle. A wave is emitted by the antenna. As soon as the pulses reach the surface of the medium, it is reflected back to the electronic module. Level distance is directly proportional to the flight time of the pulse. The measured Level data is converted into 4-20 mA DC analog, isolated output. With reference to the time taken by the pulses to travel from transmitter and to reflect back from the material to the receiver, we can determine the material level. This series of radar level meter adopted 26G high frequency radar sensor, the maximum measurement range can reach up to 70 meters. Antenna is optimized. Further processing is done by new generation microprocessors which have higher speed and efficiency. This transmitter can be used for level measurement of reactor, solid silo and very complex measurement environment.

Salient Features:

• Small antenna size, easy to install; Non-contact radar, no wear and tear, no physical contact with material
• Almost no effect of corrosion, bubble, water vapors. It is also not effected due to change in the temperature and pressure of the medium.
• No effect of dust. Works well in highly dusty environment.
• Due to short wavelength, the reflection of solid surface inclination is better.
• As beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
• High signal-to-noise ratio, the level measurement in fluctuating state can obtain better performance.
• Product can also be used in hazardous area
• Radar level transmitter find applications in level monitoring of liquids and powder, granules and solid material. It is suitable for highly dusty environments such as cement industry and is less affected by environment effects like dust, wind and rain.

SMARTsaa make Vibrating Fork Level Switche find application in food , packaging cement, steel & power generation industries for monitoring level of free flowing products like fertilizer, food grains, coal, sand, chips, granules etc. Switch is Ideal for products that do not have heavy build-up on fork. Can sense dense materials like cement. It also senses extremely light products like styrene. Not recommended for mud, slurry, sticky material or water with high turbidity.

Operating Principal:
Vibrating Fork Level switch contain Piezo-electric crystal in the probe, which causes the fork to vibrate at a frequency of 125 Hz. It detects the presence or absence of material and actuates a relay. It gives point output, indicating high & low level alarm. It is having compact and robust design, suitable for side & top mounting. The constant vibration of the fork provides self-cleaning characteristics. The change in vibration is detected by circuit which causes the relay to change state after few seconds delay ( about 2-3 seconds). When fork is free from material relay reverts to its normal condition

Features:

• No calibration required, simple to install.
• Performance independent of material characteristics i.e. change in conductivity, di-electric constant.
• No moving parts, hence no wares and tears.
• Weatherproof enclosure, SS 316 for food industry.
• Field selectable operation logic: configurable high or low point switching.

SMARTsaa offers range of RF Level Switches with special ceramic and Teflon insulation for measuring level of fly ash in ESP hoppers and level of coal ash in silos. As fly ash has bulk density of approx 1000 Kg/ m3, level measurement is very critical. By using SMARTsaaRF, level of coal ash is monitored effectively and accurately. Special sensors with Ceramic coating for areas where temperature can reach up to 450 degrees and Teflon coating where temperature can reach up to 200 degrees are developed.
The protective coating makes it abrasion resistant and enhances life of probe. Special Coat guard circuit makes this probe immune to the deposition of thin layer of material on probe.
