Description

SITRANS WFS300 and WFS320 sensing heads are used in applications such as product ratio, batch load-out and process feed rate control. The WFS series of sensing heads has been field-proven in thousands of applications, with some units providing over a quarter-century of reliable performance.

 

The  WFS sensing heads use only the horizontal force created by impact of product upon the sensing plate and then apply the horizontal deflection to a highly reliable Linear Variable Differential Transformer (LVDT). Friction-less pivots exclude the vertical force from the sensing process and the LVDT travel range is controlled by a coil spring selected for the specified full-scale flow rate. A viscous fluid damper provides mechanical damping in the event of pulsating flows.

 

The LVDT converts the horizontal movement, proportional to the impact forces into an electrical signal, which is converted by the integrator to time-based flow rate indication and totalling. This method of sensing material flow has been proven best in thousands of applications all over the world.
