Milltronics TASS is a compact low-profile, wheel-driven return belt speed sensor, ideal for use on mobile crushers and in constricted spaces. Milltronics TASS speed sensor operates in conjunction with a conveyor belt scale, providing signals to an integrator which computes the rate of material being conveyed. The trailing arm speed sensor monitors conveyor belt speed, with the output signal transmitted by cable connection to the integrator. The TASS output can be applied to any Milltronics belt scale integrator.
