Sumedha Microware

We manufacture a wide range of Electronic Belt Conveyor Weighers (Belt Scale) and Weigh Feeders that are used to measure the flow rate of Bulky materials transported on a belt conveyor. This flow rate is received as a product of Belt Load & Belt Speed and integrated over time to derive the Total material delivered over the Conveyer.

• This integration is available in the form of impulses that are added up in a totalizing counter for read out.
• The Flow Rate is indicated on a 6 digit Bright Red LED Display.
• The weigh bridge {weigh frame) is a simple frame type structure which can very easily be incorporated into any existing conveyor.
• The weigh Frame is pivoted with fully sealed bearings.
• A single idler on one side of the frame takes the belt load the other side of the frame has an adjustable counter balancing weight that acts as a mechanical tare to offset the dead load of the Weigh Frame components & idler. This allows for a full range of measurement,increasing the sensitivity of the system.
• The loadcell is of precision strain-gauge type designed to utilize the full material load.
• The Speed Sensor is a high Resolution digital tachometer device that is fitted onto a wheel. The wheel rests on the belt and is driven by it - while in motion.
• The dc millivolts from loadcell and the pulse output from tacho are fed to the electronics for evaluation of flow rate & totalizer pulses.
• The Electronics multiplier unit is housed in a compact, modular 19' rack unit for determination of delivery rate & delivered quantity.
• All display & control elements are built into, the front panel Of the instrument, facilitating quick and easy functional checks, zero correction & span checks at anytime.

Features:

• Belt Conveyor Weigher designed to Client's specs.
• Precision strain-gauge based Loadcell.
• High resolution (pulse) Speed Sensor.
• Software multiplication of belt load & belt speed.
• Zero load monitoring and suppression.
• Modular construction with multiple displays and light touch membrane keypad.
• Auto Tare & Auto Cal.
• Isolated current O/p (4-20mA) for PLC.

Applications:

• Mining & Ore Industry
• Cement Industry
• Steel Manufacturing Companies
• Coal & Food Industries
• Specially designed for Hot Mix Plants with totalizers for individual materials plus cumulative total.

SM2618

We offer an extensive range of Weigh Feeder (SM 2619) that has Two Control Modes: Volumetric & Gravimetric. Weighing is of Single Idler Type. Provided with easy and highly user-frendly Auto Cal for Rate & Speed Calibration. The Flow Rate is closely tracked in a Closed Loop by a PID and the Flow Rate is maintained at a constant value by a Variable Frequency Drive (VFD). Closed loop speed control is achieved by using a state of the art IGBT Technology & the PID is a highly user friend lyand compact module. The Belt Conveyor is Direct-Shaft Driven to achieve very smooth running of Belt.
