The MB-UB1 M185 Counter weight assembly facilitates mounting the wheeled encoder under the conveyor belt (or roller). It provides a single pivot point so the wheels maintain contact and alignment with the belt, compensating for up/down and some sideways movement of the belt. The 2 weights doubles the force of the measuring wheel against the conveyor belt. No Rod.
Wheeled Encoders: R21, R21-P, R22, R22-P, RH and RH-P
