Ash Level Sensor For Esp Hoppers

Approx Price: Rs 3.5 Lakh / Unit 
Minimum Order Quantity: 1 Unit
Product Details:
  • Model Number: SMARTsaaCAS
  • Supply: 85 -260 V AC
  • Out Put: 2 C/O relay Contact as well as 4-20 mA
  • Mounting: From outside the hopper

SMARTsaa, an associate group company of Protocontrol Instruments offers new concept of level measurement of coal ash in ESP hoppers.
It eliminates use of RF level switches which fails at site and 3 D Radars which are costly and non affordable. By using this product the operating efficiency of ESP hoppers improves drastically as proper level management for effective removing of ash is now possible. Special models with wireless remote and control unit make it easy for centralized data collection of plant hoppers at one place.
  • No radioactive Source Coal Ash Sensor: For fly ash level measurement of ESP hopper
  • Naturally Occurring Gamma-ray Sensor (NOGS) Technology
  • Do not require use of an artificial radiation source
  • Non-Contact Solution for Fly Ash Level Detection
  • Unique design that withstands harsh environments
  • Positioned completely outside the hopper unit having absolutely no contact with the coal ash materials
  • Easy to install, no need to drill a hole in the hopper or pressure tank
  • Long lasting, the sensor will not be damaged by falling ash
  • Accurate level measurement, do not get affected by ash built up on the wall or high temperatures
  • Installation and maintenance can be performed during regular plant operation so no shut down time required
  • Able to differentiate between the ash sumps built up on the container wall and the actual accumulated ashes inside the container to provide accurate ash level readings
  • Able to function very well in harsh working environments

SMARTsaa , an associate group company of Protocontrol Instruments I Pvt.Ltd,offers an innovative way of ESP hopper monitoring. SMARTsaa CAS PT is new product introduced for measuring fly ash level in ESP hopper and monitoring condition of ESP hoppers by non contact way.

Salient Features

  • Portable Model
  • Gives ash quantity % in ESP hopper
  • Indicates rat hole formation
  • Indicates ash deposition on the inside walls of hopper

Application :

Fly ash storage silos are used to store the fly ash removed by the ESP system. These silos are very large and hold hundreds of thousands of pounds of ash. Because the ash is very dusty and the conveying system is pneumatic, a large amount of airborne dust is created inside the silo environment. These dust clouds are so severe that they can “blind” Radar and Ultrasonic sensors. CAS has proven to be a reliable and accurate level measuring device for this application.

HOW SMARTsaa CAS PT works:

Uses Naturally Occurring Gamma-ray Sensor (NOGS) Technology based Product introduced First Time in India by SMARTsaa!!

Do not require gamma ray source, hence no approval formalities

Detects gamma rays from coal ash from outside the hopper

Coal Ash Sensors CAS does not require the use of an artificial radiation source. They make full use of the naturally occurring trace amounts of radioactive nuclide in the environment. Mounted in a fixed position, the ash sensor is able to measure changes in the strength of the gamma rays present as the quantity of ash material fluctuates. CAS sensors have a dedicated signal handler that can distinguish gamma ray signature given off by the ash material from naturally-occurring gamma ray present as background noise in the environment. This provides an extremely accurate reading of the level location of the ash material present.

You need to tare the hopper initially only once to get the reading and output

SMARTSaa CAS gives additional information like:

  • Ash quantity in hopper at the particular time
  • Rat hole formation
  • Ash Deposition on the wall
  • Advance indication about hopper condition
