1. 2010 Teddington Valid Until 18 July 2020 Middlesex TW11 0JZ Reference No T1147 0006 United Kingdom Descriptive Annex 1 INTRODUCTION This pattern of an automatic continuous totaliser belt weigher designed to weigh large quantities of loose material from bulk to bulk is designated the IPC 14 It comprises awelghing platform aspeed sensor an integrator type IPC 14 2 FUNCTIONAL DESCRIPTION 2 1 Mechanical 2 1 1 Weighing platform The weighing platform is designed to react only to forces perpendicular to the line of the conveyor belt It consists of a fixed support frame static and a live frame dynamic and may include a ramp section bridging the static and dynamic parts The static frame is the main support between the conveyor stringers which in turn supports the dynamic frame including the pair s of load cells The dynamic frame supports the scale idlers and transfers the weight of the material to the load cells As the material travels along the conveyor belt a force is exerted through the suspended idlers to the dynamic frame The movement in the load cell is sensed by its strain gauges when excited by voltage from the electronic integrator and produces a signal proportional to weight which is returned to the integrator 2 1 2 Load cells Any compatible load cell s may be used providing the following conditions are met There is a respective OIML Certificate of Conformity R60 or a test certificate E2.
