 The Milltronics MD-256 speed
sensor is a high resolution shaft driven speed sensor that operates in
conjunction with a conveyor belt scale, providing a signal to an
integrator which computes the rate of material being conveyed. At only
1.22 kg (2.68 lb), it is one of the lightest and most durable units ever
developed for monitoring conveyor belt speed. With its rugged cast
aluminium housing, it is suitable for outdoor installation, and its low
weight prolongs bearing life.
It is directly coupled to a
rotating tail or bend pulley shaft to ensure accurate belt-travel readout,
eliminating problems caused by belt slippage or material build-up. The
MD-256 converts shaft rotation into a pulse train of 256 pulses per
revolution using a high precision rotary optical encoder. The digital
signal is transmitted as speed input to any Milltronics integrator for
calculation of belt speed, flow rate and totalized weight.
This high resolution speed
sensor provides a frequency signal proportional to the shaft speed,
enabling low or varying shaft speeds to be read accurately. The quadrature
type shaft encoder prevents erroneous speed signals due to vibration or
shaft oscillation. The MD-256 is easily mounted and is bi-directional for
either clockwise or anti-clockwise belt travel.
