Principles of operation of torque power (absorbing) dynamometers. An absorbing dynamometer acts as a load that is driven by the prime mover that is under test (e.g. Pelton wheel).The dynamometer must be able to operate at any speed and load to any level of torque that the test requires.
More MessageWhat is a Weigh Feeder Instrumentation Tools
The load cell measures the weight of a fixed-length belt section yielding a figure of material weight per linear distance on the belt. A tachometer (speed sensor) measures the speed of the belt. The product of these two variables is the mass flow rate of solid material "through" the weigh feeder

required to measure two variables. The first variable is the actual weight on the conveyor belt and the second variable is the actual belt speed or belt travel. The weight of material on the conveyor belt is obtained by measuring the load on one or more idlers. This load can then be expressed in terms of kg/metre (W) of belt.
