FSG15N1A Contact force sensor For Blockage Detection Hemodialysis Machines

Working Principle:

When a silicon piezoresistive element is bent by external force, its resistance increases proportionally. The external force is directly transmitted to the silicon sensing element via a stainless-steel plunger, causing the element's impedance to increase in proportion to the force. The resistance changes in the bridge circuit generate a corresponding mV output signal.
